mouth cancer radiation therapy - CLINAC - clinical linear accelerator

[TypesEvilAspieEyes]

What's the agility of the linear accelerator , leaf position to fit the tumor that it's targeting . I been looking at teletherapy, radiation therapies from Elekta and it's software

[TypesEvilAspieEyes]

Subscribed to you . @bionerd23 u cool

[javordrnasin]

And you people still believe this is actually helping people...

The jerky movements of a twenty-year-old LINAC gantry. Does this have an MLC?

[bionerd23]

@douro20

yes. cheaper than casting lead blocks for each patient, i suppose.

[Dembadomba]

ok no video.. ive seen one now.

[Dembadomba]

do he shake or is it something else? it looks scary... man i aint going to smoke. or try it. plzz make a vid about that "mask".. wanna take a look.

[bionerd23]

the mask as well as many more pictures are on my flickr photostream, anyway; the link is on my youtube channel page. just search for mouth cancer on my flickr, and you'll find them.

@bionerd23 If only you had a linac at your home

[SuperVikingwarrior]

How is your friend (the cancer patient) doing at this point?

[bionerd23]

not too good; he had to undergo chemotherapy in combination with this radiotherapy, but the cancer seems to have come back (he's got a lump / mass on his neck). he's currently not getting it treated, though; guess he's sick of all those treatments... however, he goes to check-ups, which is good.

5/5! I smoke, and I'm into radiation (studying it, that is), and I do know that in nature, Po-210 and Pb-210 atoms have been known to attach themselves to the fibers on tobacco leaves. I've heard of this a long time ago, but radioactive isotopes are capable of many strange behaviors... It's hard to quit smoking... The best way is to NEVER START! I should really take this seriously! Today is my 26th Birthday. Right now actually, 1:00 PM! I need to quit smoking! Thanks Bionerd23!

[bionerd23]

happy birthday, now you're as old as i am... :P ;)

...and good luck with quitting smoking!!

[kjarlsn]

There is no radiation when its rotating:)

[Zardas11]

i would like to learn more about radiation in general, any good sites to suggest or have any pointers?

[bionerd23]

wikipedia is always a good start... or get some books from the library, very good start, too.

[Zardas11]

thank you.

6000 Rads????

I thaught that 1000 reds was LETHAL

[bionerd23]

as a full body dose, about 400 rad can be lethal already. however, this is NOT a full body dose; the patient receives the absolute majority of radiation bundled onto his mouth and neck area.

@bionerd23

Ok thx im watching this because my 43 yr old mom is under going radtion theropy i hope shes ok...

[bionerd23]

i'm sure the doctors know what they're doing, and are not putting her at unnecessary risk with the therapy. good luck to your mum!

[sanitary103]

its fractionated over a period of 5-6 weeks typically; not 6000 in one shot

[bionerd23]

yeah, of course. 6000 in one shot would cause his face to die off.

[Zardas11]

Love your vids

(i couldnt help but feel like it was a rave)

[JayandJenn07]

I do agree about the beauties in this technology, but I am kinda surprised at how jerky the rotation is. I operate and Program CNC Mills and Lathes, and the accuracy they MUST have is in the .00005 of an inch. the human hair is .005, But those machines have an average cost of about 100k and i can safely assume this machine is well over a 1mill. It would just make since to me to have the same quality of axial rotation as My machines.

The photons cam was crazy. wouldn't want to be in their.

[bionerd23]

yeah, i noticed that, too - well, i still hope it's accurate enough to do its job... this machine seems to be from 198X something though, maybe that has to do with it.

[coilgunman]

yes!!!! today arrive my gamma-scout

and congratulations for your videos are very interesting, you are my idol

[cyclenut]

Yes, tabocco and smoking is BAD!

You flashed important information that I could not read.

This must not be America, 40 and not obese.

Bionerd23, your are so cool!

[bionerd23]

they were not really "important", they just tell what everybody should, in theory, know... or at least is in the description, anyway. you could press pause to read it, though. :)

as a sidenote, this patient is german. not that it matters much, but, well.

[LechuCzechu]

The whole machine looks like a mysterious device from a Sci-Fi movie :) . The red lights indicating whether the radiation is on or off are the best - HAL9000.

I've got a question: since this machine is a liniac its basically acclerating and emmiting electrons - which are almost like beta particles - ist that true? Are the photons cought on the CCD of your camera, result of Bremstrahlung of the betas (and therefore some portions of gamma) or are those just scattered betas reflected by the floor?

[bionerd23]

well, the red lights actually tell info about the rotation of the linear accelerator itself, collimator, gantry, etc. - but they do always turn off when the radiation is on for some reason. :)

as far as i know, the produced electrons in this CLINAC hit a target, resulting in a high-energy photon beam that is used for the treatment. thus, i guess my camera is recording scattered photons. :)

i'm quite glad he's not being treated with protons, that's for sure, that'd ruin my camera CCD. ;)

[Ch3mG33k]

This is one of the most epic videos I've ever seen. Best of luck to your friend : /

[bionerd23]

thanks a lot... and stay tuned, as i will document further steps.

those will often be photos, though, so check out my photostream, if you want (link is in the description or on my channel page).

[enotdetcelfer]

wow that's pretty cool haha

[enotdetcelfer]

it would be cool if you could catch all the impacts in one long exposure. still cool tho thanks for posting. :)

[bionerd23]

that's true, but i cannot set my cam to record more than a few pictures for the next ~3-4 minutes automatically, and that is too short... the machine only starts radiation treatment after adjusting for a few minutes, and nobody can enter the room once that progress begun, so... i suppose it's impossible, at least with my camera.

[bionerd23]

however, i did record a black video (lens covered) of the process by having the patient wear a "box on a belt", and the results are quite cool. results will be up on my youtube soon... ;)

[alin0steglinski0]

i can agree the machine is beautiful but i definitely do not want to be on the patient end of it...

[bollywoodmusical]

Your friend is very courageous. I hope your videos will help some peope to stop smoking.

[bionerd23]

thanks a lot - i hope so, too.

[shadowthewedgehog]

that machine is so intimidating.

[sciencoking]

waah, 60 Grey o_O
