 ground categories where the development in biomedical engineering is viable and necessary. First of all the educational, even if it's academic, either it's professional, advertisement or marketing, you can promote your stuff in system installation in a medical environment, so you don't make any grand mistakes with a topology. And engineering design options in industry, you don't waste money, you can try out different setups and geometries, so it's kind of useful. And in the education, probably using a 3D virtual reality environment as a part of training in mythology allow students or application specialists, the workforce of every country, to experience entirely new side of training. And real-life scenarios can be implemented as normal functioning, maintenance and probably the quality control which is the most important part. Education, the biomedical engineering students or application specialists can be trained and evaluated on the physical principles which the functionality of the medical equipment is based. This type of technology breathes life back into traditional computer-based learning and reawakens the enthusiasm in users who are used to this technology in other circles outside of the training. About the marketing, it combines the high-end technology and creativity of the graphic designers and the technology that already exists and can give an opportunity for them to reboot the marketing problem that many companies and corporations are already facing. The interactive combination of the 3D geometries, the internet marketing is an effective commercial strategy. And about the system installation, you can simulate the motion either of the location so you can avoid the inexpectable errors in the biomedical engineering field. And as an example you could have collisions so you could break something and if it's an MRI, a magnetic resonance imaging machine, we're talking about a 5-ton machine so you could kill somebody. About the design, simulation modeling gives you the opportunity for system designers to test different design options so you can have a better placement. So the design specifications are met by using virtual prototypes rather than having just physical experiments that can show you particle collision. You just need to see the proper geometry in the proper space. Let's see some biomedical engineering systems to get a better picture of how complex it is and why do we need to build it. This is an x-ray scanner from Commutic Tomography. This is the show-off of the company. It's rather complex. It's consisted of many different parts inside this machinery. In biomedical engineering we always have three basic parts. The first one is the primary effect. We might have a human body which might get a radio-nuclide so it can get to the cancer, let's say. The radio-nuclide might get farons outside. We must trace them so we must have a detector. The detector will get an analog signal. The analog signal will be turned to a digital by us and a lot of computations come in order. So this is a demonstration of a company. But this is a real-life engineering maintenance of a Greek hospital. That's the real situation. The basic problem in this era is that an engineer cannot possibly come and pay a visit to any hospital or find an engineering system in need to learn how it's inside. And the students almost never find out how a machine really is inside. Even the application specialist doesn't know how it's inside. That's why we need to invest in creating what's happening. Nothing probably. Connection is lost. Oh, here we are again. So the most difficult part in the biomedical engineering education is to show them how the system is really, how it really works and how it is practically inside. The problem is that in the most facilities, in the most systems, you cannot operate inside the machinery. I'm a biomedical engineer and I've been to hospitals. It's very difficult to see the system from the inside. So this is another one, modality. It's the post-transmission tomography. As you see, it's very complex. It's very complex and it has many different modalities inside. You have the things that square around there, the detectors, the electronics are from the inside where nobody really understands how they work and why they have all these cables. You have to be in electronic technician about that thing only. So you combine four or five different people to consist one system. This is another realistic photo of a pet. So what's the aim of this project? The development of a virtual laboratory which describes 10 medical instruments of biomedical engineering and their related physical processes. So what do they require from us to have an educational tool to be easy to use, not to download something that I will, so the user will make a setup of something, an installation of something, something very easy. So they ask us a web application. You just click and the browser plays, something like that. Accessible via internet for every student, self-guidance through the 3D world so you cannot make him, you can restrain him, let him guide himself through interaction with the system environment of course. And let's see the advantages of blender and why I did this in the blender. We have compatibility with other applications. Let's say you can export your dot blend to a dot 3DS or a colada or something like that. You have Python, a very very good language because it's all object oriented and you can connect different modalities. Let's say you can connect an Arduino or a CNC or a 3D printer with Python. It's open source. So everyone can use it and there is no company coming to RST with handcuffs if you do something or ask for money for that. You can invest as much as you want to it and you can upgrade it the way you want it and you can bring it to your own shape. It's user friendly GUI and it's really easy to learn how to use it since I'm eight, nine months graphic. I'm trying to be an amateur graphic designer in blender. And the blender community is pretty interactive. You can ask them questions, they can respond you back and this is a big thank you. And also blender gives you high end capabilities to make realistic models. So it's the software for the job. So what was a workflow? A workflow was achieving a well-in-depth knowledge of biomedical engineering machines since they're composed from a large variety of different parts, different scale. That means that you have to contact four different scientists or four different engineers or many different persons. So and achieving a well-in-depth knowledge of the biomedical engineering and starting with a smaller and the most complicated parts. The first geometrical approach was done in blender. I made the 3D structure in blender using basic meshes curves. I was an amateur so it was the most easy part. The most difficult part except taking the knowledge of the machine in the system was to export from blender to 3DS because most of the geometries tools and stuff don't work in 3DS. The 3DS is an old one, is an old expert and you cannot make a big script. It's going to be very large. So you can't make very many a giant amount of curves, you cannot make a giant amount of meshes, you must be restrained. But this is also good because if you make a web application you cannot put tons of data in it. So everyone can open it easy and it can run smoothly in any computer. That's very useful because we're talking about students they cannot all students cannot afford a Mac. Finally the complete mesh is exported as I said in 3DS. So it can be applied as a class .as3. I used flash code in order to make the web application. So I made the interactions in .as3. I developed the flash code but the geometry was from blender. And let's see now. Let's see this one here. We have a workflow how it was properly done. You can see by the left side a proper clinical MRI. You can see in the center it was created in blender in a native form. And we have a simple very simple GUI in the right side which is the browser part. It's just a browser. You click the external link. It connects you to the server which I've uploaded all this stuff. And you see the GUI of our application. What you really can do in the in the most right part you can walk through the MRI. You can see any part you wish. And in the bottom right in the bottom right section you have the ability to take off parts. I made that in in the flash code. You can delete parts and you can insert parts. You can you can have a guide before you put them inside there. You can have a guide which will guide you through what he should erase first so it can get the skin part by part and understand what he's taking out and what he's seen. Imagine if you have a car and suddenly the cylinders come out. If the mesh is outside still you cannot see the cylinders. So you take it part by part. Well we can see some results here. This is an optical microscopy system. It's it's a general bio emission system but there are many modalities in that. We can see in the center the numbers two one three five six. This is the main modality of this system. The bottom structure at the five is where the mice is coming. And there is a very simple engineering mechanism of how to proper hold the mice when it is in anesthesia. This is a very simple machine to hold the mice but still an engineer must make it. So it's very useful to construct something that can go from a system that's meters to millimeters with just one roll mouse roll. That's the nice thing about blender in 3v. This is the top view of the implementation. The top view if you see it from the from the above from the tube you see from above. This is the top view from the implementation. So you can probably understand why if you if you play this you can understand why fixing the rotor in the islands is you can understand why it zooms out and zooms in what really changes why these things are moving. And this is a static photo I've taken which shows the the smaller minimal parts that hold the mice. So you can go you can go zoom in and understand how it's made. These things we're talking about are microbes. Micros comparing to the to the whole system which is about something less than a meter. Microns are very small so you cannot understand how it's made. And a photograph doesn't really help if you don't see it operating you can understand that this is a speck. The speck is used in nuclear medicine. It's one of the most basic parts of the hospital when we're talking about medical sciences and nuclear medical sciences and that's a 3d prototype I've made in blender. And then I took it to the crap environment of 3ds so I can make it aware of publication. And this is how probably you can see it. The good thing with most devices and systems is that you can see it operate. So you see the cameras they can rotate you can see a maintenance problem the rotors are not rotating that means that probably something is not going out something is going wrong why should it have that happened. So you can implement more things in the educational process you can make probably some questions. So while the simulation is done you can pop up a question you can have an answer for possible answers from the downside keep all these save them in a database and maybe evaluate the student or the engineer it's pretty interactive. Some of the most complicated machines of our science are now interactive by being separated to partitions because when you have the whole speck machine system you saw before we also have the detectors the power supply we have made it in parts and partitions you cannot only see the whole machine and rip things off the ripped things off are also separately demonstrated if you wish. So we separated them in partitions you can peer through the exterior in the interior you can take you can take a sneak peek where it's in reality you cannot. In addition there's a turn-based disappearing tool which it's kind of nice and you can also make some exercises on them so you can prove your educational part. So what are the future plans we make it we want to make it a standalone blender project because in 3ds and in flashcode you don't have much flexibility as in blender you can make tons of things and I'm still an amateur I can learn a lot of stuff yet for instance I couldn't make very complex meshes because 3ds is not it's not it's not being extracted in 3ds and we can all we can also expand the variety of the systems that requires feedback from the students that requires feedback from engineers from the scientific community we also need the knowledge basis from the engineers because it's very difficult to open a system I made one year to find an open MRI because the magnetic resonance imaging machine because the magnet the force field it never it's never down you have 3 tesla all the time up you cannot go close the magnet will pull the camera and make an accident it's not that easy. So if we have a funding maybe we can we can improve that and at this stage the virtual laboratory is an educational tool but it can be upgraded to a professional maybe a commercial maybe a specific implant and implementation for a facility they want to make something to educate or either promote something for anyone's needs but for for universities there can always be a elite aversion so they can use it to educate students since I made for education and I learned from open source so I want to give I want to give to the open source community so let's make some acknowledgments here my let I want to thank my my professor George Ludus he was the organizer of this of this project the blender community for the tutorial guides and it's and it's person that has volunteered in creating something to educate someone the creators of blender because they made a terrific job so far and they still do my institution who was the establishment where we made all this and of course you for your patience I left many minutes for questions because all the scientific experiments and applications mostly are useful where when there are questions and discussion so I'm waiting for your proposals but you're not able to get some original plans for the machines because I think these are close commercial products this MRI machines or whatever so you are basically doing something like reverse engineering that's that's the job you're not doing you can do either reverse engineering either you can do with engineering from the start build something from the start but not in this project blender gives you the opportunity to create meshes to create ask what you do that's what I do basically I create meshes and objects but in this project we wanted to make a standard version of a system so somebody can educate himself and guide himself through this software to learn the most basic structures of a system which is very complex and he cannot interact with in real life only as a patient and still as a patient unfortunately you don't have many opportunities to see the environment you're very you have other things to think about what you've broken your leg for example so any more questions just to follow the the question before could you not get the plans from the from the manufacturer no because we building and also at what point is the the simulation of the of the functions like can you do you have all the the controls and can you simulate the amount of information you get and all the other things that you actually do when you operate these machines I can gather data I can make data and since it's python controlled I can probably store any information or apply any mathematical or physical model that can be applied in python and that's quite nice the point is that it's not physically verified so I cannot make simulations of physics experiment that's my background I used to do simulations for nuclear medicine and interactions of photons and subatomic materials the thing is that it can be interactive with the students you can get data from the students so you can learn if the educational course was useful and you can implement anything you wish but it requires good programming skills and a high educational status because you cannot use everything in blender and in blender in python and to be and it can be related to the physical process uh for instance you can make something look realistically good but it doesn't mean also that it will operate in real life the same way you cannot predict everything it's a lot of different the different worlds the visualization with the real structured data yes so could you could you in in in detail yes tell me what's the different to blender so what what do you offer do you offer models of uh crts or uh what what's the framework oh what's the framework um so what what everything is shown I could do in blender if I have these models but what what you did what where I can I can join in or my point is I I got it my point is that everyone can do it the problem is that the companies of biomedical engineering they're not giving away their the structures because this is the commercial you as zeemans for example or philips or general electric cannot give away their their structures and the and the inside of the machines because this is the way they build it if they if they give it away uh someone else will build it and maybe cheaper and there will be a marketing problem uh the problem is that you also have to know what you're making so you have to combine the scientific community with the blender artists uh so you have a better result either either educative even uh promotion even in marketing and this is a call for every uh scientist and everyone with scientific background if you ever made something in blender it would be nice to introduce it to the community of blender so uh we can possibly work out we can work something out it's uh it's really nice to see people cooperating in uh in an environment as blender and uh i'll personally make a call through blender artists uh to make uh in these in this conference to have a small i don't know one hour whatever ton is uh wants us to have just a small talk flash talks of scientists that they've made or they want to make something in blender so people can have job opportunities maybe or um they can improve their um they can improve their skills and uh you know imagine it's a different thing imagining things and uh making a very not so well illustration and it's a different thing understanding how to make it the how to make it is a very difficult thing how to create a mesh how to create uh but in order to be educational not just to create it if you make lots of details like shadows and lights and things it distracts you it's an educational tool so so you said you built some kind of like web application uh uh could you could you present this to us if there if there is some time left sure what what it looks like and how you can maybe take apart your i am your your your machine your your imaging machine sure you and we have one minute left so is there any question i will search it while i agree that it's probably quite difficult to get the real plans from companies but they're also in too much detail so you need to explain the different functions and different parts of it and these are known because they are the same for all the machines so you have to implement not a specific machine you have to implement the concept of an MRI machine so that's different so i think you can do quite a lot if you understand how an MRI machine works or or a CT machine or whatever it's the most difficult part to understand what it is consisted of and how it works it's the most difficult part in every display in every virtual world i think the most difficult part as an amateur it's my personal opinion it's most difficult part is till you reach to the point that you know what you want to build still there are medical physicists at the operating machines and they are very well trained and they know how the machine works and they know conceptually what is going on and that's what you want want to convey so you have to talk also to those people medical physicists most of the times don't know how it's inside they know how it works but they don't know how it's inside but there may be different green the nettles and the other ones but then you have to buy medical engineers and that's my group yeah that's the problem you have to combine many people for a big project so i think i found the site so we can see let's see we can check which one the MRI here we go yes this is flash you just click we would just make one click and and the flash initiates it says loading please wait it was a greek software so of course i will translate it if an institute wants it i will translate it i don't know why the model is not loading i can go to another one maybe stop close the torrents the fluorescence was going before oh it it was going oh okay no problem no problem oh okay sure sure sure i think i got fluorescence somewhere like here here we go i think this one's this one should be normally functioning so i hope they don't have server problems back in Greece because this is embarrassing that's nice that's very nice so this is one setup of a basic of a very basic orthogonal laser which probably can give you a laser beam which will touch a very special chemical solution which will be urea which will go to a state which photons comes out why photons comes out this is 30 minutes talk so this is a very easy way to explain why this chemical solution by this laser pointer source gets photons out because people cannot understand why but basically engineers cannot understand why biomedical biomedical engineering also has the chemistry part and the biology part but we don't need to know in explicit detail why these things happen we just need to know how photons get out something happens photons get out that's it we just need to visualize it we got it that's it we need to make the machine we don't need to make the chemistry you have to be you have to be quite simple about it so oh a state one of course sorry for that i just want to you know you know i want to flash between some different projects it's okay i want flash this is a photomultiplier it's basic concept is to when photons struck in the photosensitive area which is up here the photosensitive area which is at the top electrons come out sure sure okay there was a call so i could show something so it's okay i can i can shut it down right now photons can come struck to this photosensitive area if i had a mouse i could probably show you a lot more we can we can use the GUI to disappear to disappear some basic geometries to show when the photon strikes the photosensitive area when the photons hit the photosensitive area we'll have the electrons coming out from the from the from the other spot so the electrons can be stacked up to the cathode there's a very tiny slit where they will all pass through this is a very difficult thing to get all the electrons together stacked up together this is the the blizzard like multiplying electrons state where they bounce from one side to the other and we collect them at the end so this is our analogical signal as i said it's not difficult to make the big mesh it's difficult to understand how it works because they don't let you understand it since time it's the standard i'm i'll think again for your patience i'll think also time
