 So thanks a lot for the introduction and thanks for having me as a speaker here. I'm the CEO of Exyscope. Exyscope is a young company based on research from KTH and Stockholm. And we build what's called the next generation X-ray microimaging. I'm going to tell you more about that. But first a few examples, a little teaser about what we do. We do imaging with face contrast technology to get better contrast for low sea samples. So basically anything organic. What we have been working the most on and where we have a lot of experience is in the biomedical applications. But we're also exploring a lot of other fields. For example, we have tried polymer technology, archaeology, and the applications I'm going to show you today is of course food and packaging. The samples that we can study with our technology are from a few millimeters to a few centimeters. And the observable resolution that we get is one to 30 microns. And this is the take-home message today that if you need good contrast in centimeter-sized samples with micron or tens of micron resolution, I might have something for you. But first, before I go into the applications, I would like to tell a few words about X-scope. Since we are a very young company, I would guess a lot of people don't know about us yet. So everything started at the KTH Royal Institute of Technology in Stockholm, where we did research on propagation-based face contrast imaging technology. We have been using and still use excellent metal jet sources for our imaging. And as I said, we have been working a lot on biomedical imaging applications. And our work has been focused on making good algorithms for how to acquire images and how to process the images to get good image quality, specific to the face contrast technology. In 2019, we founded X-scope, which today has five employees. We just got our in-house imaging system prototype ready. And we are continuing the development on this one. And we will be ready to make our first customer deliveries in 10 to 12 months. And I would also like to mention that we're opening up an imaging as a service. For those of you who don't want your own instrument, you can send samples to us and we image them for you and you get the results back. So I guess some people here don't know about face contrast technology and some people know a lot. So I'm going to go through a little bit about the basics. The propagation-based face contrast is quite similar to conventional imaging, where you have an X-ray source, you have a sample, and you have a detector. The difference is that we keep the distances here marked as R1 and R2 a bit longer than in conventional imaging. And this gives the radiation the ability to propagate. So tiny refractions in the sample give rise to contrast, which can be detected. To do this, we need to have a bright X-ray source with small focal spots and a high flux. This can of course be done at synchrotrons, but we use X- elemental jet sources and put this into a compact X-ray system. For the detectors, there are several options. You can use either a medium resolution or a high resolution detector. In the system that we build, we make space for several detectors so you can shift between large field of view and high resolution quickly. We do tomography, and for that we of course need a rotation stage. And we also use six linear stages to move things around and make it an automated process. So why would you use face contrast? Of course, the obvious benefit is that you get much better contrast, especially for low C materials, which is often the case in food and packaging. It's a dose efficient method. The scan process is very simple. Similar to conventional tomography, just take images and rotate. And the scan times are fairly short. So I'm going to show you a couple of application examples within food and packaging. These examples are on a proof of principle level where we wanted to test our technology and the ability to use it in food and packaging. So it's been made on material that is widely available in the grocery store. So my first example is tomography of extruded foods. Here it's a cheese cruncher. And to the very left you see a single slice from the tomography where the total tomography was taken in three minutes. So this is for a compact X-ray system. It's fairly fast. If you zoom in, you can see that there is clearly sufficient contrast to differentiate between fat and carbohydrates. And of course the salt gives very strong contrast, so that appears on the top of this image, very bright over here. So we also made a little comparison to confocal laser scanning microscopy in the same or in a similar sample, the same type. The downside with the light microscopy is of course that you need much more sample preparation. For the X-ray tomography, we didn't need any preparation at all. So we don't use any staining or any other contrast agents. Looking instead at two-dimensional projection images, we examined the same sample, but in much shorter exposure times. So what we have left here, it's a 150 millisecond exposure. And what we can see in these images is that, again, the salt grains appear very clearly. And you can easily follow the both size distribution and distribution of salt within the sample. We can also analyze the pore structures. And for that, perhaps the three-dimensional images are even better. If we zoom in in this little box, we can see that even though we had very short exposure time, 150 milliseconds, the observable resolution is between 10 and 15 microns in this image. This was a stationary sample. As a little experiment, we also did imaging while the sample was moving to simulate inline inspection. And this was our first try. We moved the sample at 40 millimeters per second. And I know this is not enough to compete with many production lines, which are much faster. But we did this as a test. To do this, we used a photon counting detector to give very fast readouts and high image quality. The detector is much smaller than the sample, but has the full width of the sample. And then the sample was moving past the detector while imaging. And even though it's moving at 40 millimeters per second, we can see very small details. This salt grain is between 20 and 25 microns, but you can see even smaller ones, which are between 15 and up to 20 microns somewhere like that. This is just an example of that. In a compact system, we can still get pretty high resolution even though exposure times are short. So what's even more interesting than a moving sample is of course a dynamic sample. And thinking about dynamic samples within food. And bread dough is the first thing that we could come up with. So we tried imaging very fast tomographies of this sample. So what you see here is a plastic tube with the bread dough inside. We took seven tomographies. Each tomography was 57 seconds. And then we could compile a video of how things were moving inside. So what you see here is the segmented air bubbles inside the dough. And you can follow them that in each time frame, they grow a little bigger and rise a bit upwards. These bubbles that we can see here are 25 to 30 microns. I also promised to show you some examples of packaging. This is a milk package, which we first imaged in two dimensional projections. This is the image of the opening of this milk package. And zooming into this box, we can clearly see that the paper fibers are easily visible with good contrast. We also did tomography to get three dimensional images. And here I'm sure there are other people here who know this sample much better than I do. We also have a background in the imaging technology. But what we can see here is that small fibers down to three microns can be seen. We can also identify different layers of polymers and aluminum. We can find a little breakage over here. There are probably more details that those who are experts in this can see that I don't see. So to summarize what we do, since we have a background in the imaging technology and the long experience, we decided to build X-ray systems. So it's an integrated system with all the equipment you need and software to make face contrast imaging. And the benefit of this is, of course, much better contrast where it's not sufficient with conventional micro CT. Since we use a very bright X-ray source, it's about a factor 10 brighter than conventional solid anode sources. This translates directly into faster imaging. So it's about a factor 10 faster. For some applications, we can bring them from the synchrotron to the lab. Of course, we cannot compete with all synchrotron applications. And as I mentioned in the beginning, we also start offering imaging as a service if you want to send your samples for imaging. I would like to thank a few people. So this work was done in collaboration between X-scope, RISE, and KTH. My colleagues, Jakob Larsson and Jenny Romel from X-scope. From RISE, it's Amanel Larsson and Camilla Ögge and Hans Hertz from KTH. And my very special thanks goes to Amanel Larsson because he was the one who introduced us to all these food science imaging applications. And he has been very helpful in this. He was at RISE at the time we did this. And he's now at Lund University and I know he's here at this conference. So thanks to him. I would like to encourage you to visit our webpage or follow X-scope on LinkedIn. And if you have questions, feel free to ask them now or send me an email. So thanks a lot for your attention. Thank you, William. Yeah, I have the same question as Tommy. What about the maintenance of the liquid jet source? People say it requires some effort. It requires more effort than a solid anode tube. It does. So you have to exchange cathodes and nozzles every now and then. Typically, it can run for several months without maintenance. So it's pretty okay. And Simone is asking, put your comment on the available incident energy range. Acceleration voltages are up to 160 kilovolts. Emission lines of the gallium indium and tin, which is in this alloy are at around 10 KV and around 25 KV. So the efficient X-ray energies are around 10 up to 30 KV. Okay. Could you, in a forum like this, could you give a rough estimate of the cost for one of your instruments? Is that allowed? It's, of course, I would like to discuss with everyone of you. It's not much more than the micro city systems available on the market. Very similar in price. So if I start chopping off my fingers now and for each million Swedish krona, do I lose a whole hand? You lose a whole hand, but you don't lose both. You're good. Any more questions? There is a raised hand. Oh, sorry, I didn't see that. I think it's just faster if I interject right like this. So thanks for your presentation. It was very interesting. I'm curious also about the range of imaging techniques you rely on. So you mentioned face contrast. Do you mean single propagation or multi propagation? Or do you do any typography, this kind of things? We do single distance propagation based imaging. We don't do typography.
