- Have you ever wondered how a linear accelerator works and what it does?
A linear accelerator is a device that produces a beam of either electrons or very high energy X-rays that can be used to treat cancer. In this video, you will see an Elekta Synergy, an accelerator that is used for radiation therapy.
Radiation therapy is a treatment that uses high-energy radiation to kill cancer cells or shrink tumors. The radiation beam can be shaped and directed to match the tumor shape, so that it can target the cancer cells while sparing the healthy tissue. The beam of radiation is delivered with an accuracy of 2mm, which means that it can hit the tumor precisely and avoid damaging the surrounding organs.
How does a linear accelerator shape and direct the radiation beam?
There are three ways to do that:
- Using the primary and secondary collimators. These are large tungsten blocks that can shape the X-ray beam into the appropriate square shape.
- Using custom blocks. These are cast blocks that are made specifically for an individual patient to shield sensitive tissue or structures. They can be made to the exact shape of the tumor.
- Using a Multileaf Collimator (MLC). This is a device that has fine leaves (usually 1cm wide) that are computer-controlled to move in and out of the X-ray beam. The MLC can create complex shapes that match the tumor shape. This is the most common method used in many countries.

Thank you so much - I'm currently undergoing treatment with one of these very machines, have a science background, and I'm the kind of patient who feels much better when they understand what's going on. This really helped me.
How did your treatment go?
@@wass006 I guess not that good...
A terrible thing to assume. A Google search shows Mr. Finnis is, thankfully, alive and well.
Me too... I don't think the technicians in the room know who clever the machine is... I guess the folk in the back-ground on the PC have a good knowledge...
@@flyduck1 he is a lecturer in computer science in Wales and as of 2023 is still posting answers to questions on Quora, so I'd say that's a successful treatment!
love how this was so educational, even though it's just a big ad for elekta
I'm a cancer patient visiting this machine every day. I barely notice any side effects, I have another 1/2 month to go, 10 minutes a day. This machine is amazing!
The animation or whatever you call it is amazing, the animation really help with understanding how the machine works, if I only would of heard the lady speak I would be completely lost, amazing animation guys, awesome.
On a scale of 1 to 10, this video is an easy 9.
Good job.
This is such a great video! The explanation is simple and precise. I had 38 daily treatments with this machine. 5 years out and still cancer free. The technology is amazing.
Good for you!!!
Thank you so much for providing this information. As a family physician, I understand the basic principles of radiation therapy for cancer, but was really clueless as to what my radiation oncologist did when 'planning' my treatment and how the machine actually worked.
I am a cancer patient and this machine has been used daily on my tumour and the site of the lymph nodes in the arm pit. I am grateful for this video presentation.
i imagine this is expensive but nonetheless, the care it must have taken to make each marvellous engineering decision must have been laborious. I can't believe the amount of care one must have to have such precise measurements and such a high level of safety. It makes me happy to know that there are people who dedicate their lives to making these life-saving machines
question is if those people would try it on their own
This is an excellent presentation. If you are being treated with a Varian linear accelerator there are a few small differences (klystron vs magnetron, placement of focus and steering coils & other components, type of bending magnets) but the principles are all the same. Bravo Elekta!
Each person undergoing Radiotherapy,really needs to watch this important presentation, Without these wonderful machines, and the people behind them,many would be clutching at straws to get help. Thank You
I am currently being treated with this device on my armpit. I was scared and knew not what to expect. This video has gave me more clarity. Thanks
I have 34 years of hands-on experience working with high vacuum systems, high powered radio frequency generators (including magnetrons), scanning electron microscopes, ion implanters (industrial particle beam accelerators used for doping semiconductors) and, industrial real time microfocus X-ray systems. I'd really enjoy working with this piece of equipment because it appears to be very well-designed and because it is used to help people in need.
Explain is fantastic and easily understand even not in a medical educated viewer like me i am in india at tamilnadu state ,my father age 63 affected in throat cancer grade 3 and lungs also damaged by TB and having more fibrotic tissues in lungs (because tb patient and long time smoker) so doctor prescribed RT/CH and they are say anything will happen while on treatment even dead so I need your suggestions for linac RT and my family is very poor family but our government started yesterday linac treatment in chennai with free so I need your suggestions please please please.....
It is nice to see the details of what is zapping me every day. Thanks for the video!
Did you make it? Still with us?
@@russellhamner4898 Yes, I'm now 7 years out on one cancer and 6 years out on another, so I'm still here and doing great! Thanks for asking!
A tip of the hat to the folks at Johns Hopkins in Baltimore and a myriad of other doctors spread around DC & MD. A big thanks to them!
Very well explained! The animation further helped to visualise and understand the concept. I really liked the addition of magnets near the end of the waveguide to further pinpoint the electrons on the target which is also unique with elekta.
What an excellent video. This answered pretty much every question (and I had a lot) I had about the machine and also the process being used to treat me for prostate cancer. Every radiation oncologist should know about this video for the education of any curious person like me with a lot of questions.
The video is so so so informative that I just loved looking at so many applications of what I have been taught in my class XII.
Thank you - this is very clear. I'm a current patient of radiation therapy, and it really helps me to understand how the technology works. This is a big help, thanks!
if only my teacher explained it like that i would've passed the test
Excellent animated presentation. I have been keen to know how this machine works as it rotates around during my therapy visits. The variable focusing system is really smart.
Incredible video. Thank you
thanks for this worthy animation its's really helpful for understanding the working concept of this complex machine
think you so much this really help me understand my assignment about the linear accelarater.
Great video. My wife is undergoing whole brain radiation under an Elekta. We are half way through her treatments.
Wow just what I was looking for!
Crystal clear and very interesting!!
I was trying to find an anime and Instead, I learned something.
Thanks. We're happy to hear this.
AWESOME!!!! THE GENIUS OF MAN FOR THOSE AFFLICTED WITH CANCER!
Now I know what they're doing to me on a daily basis, and how this machine works. Animation makes understanding easier.
went from aducating to advertising so smoothly i almost wrote about Elekta on my test bout radiotion therapy
I learned something today , teach this video teaches me a lot about how Electronic beam machines works thanks for the video :)
Nice presentation. I was wondering, to bend the electron beam you would normally use a dipole and not a quadrupole? Is that something to do with off-axis acceleration? I am assuming that the magnets near the delivery point are dipole/septum magnets. Also, are you by any chance looking into ion/proton therapy? Thanks
AMAZING ANIMATION,WELL UNDERSTOOD
Awesome
simple illustration
I am also undergoing treatment. UNC Rex has a few of these Electa machines. They’re so cool, I had to find out how they work. This was extremely helpful.
Ooooooosh thanks for this vid. it just made me to understand the primary function of this device.
Thank you so much for the clear explanation.
2021 and this is so good!
This video is very informative and easy to understand great job
i am having this treatment now. what a clear video. thank you for making it! oh, p.s. the music with mine, at guys london, is similar too.
Best wishes on your treatment. We're cheering for you.
Very interesting, the animation is really well done. Was looking for an electromagnetic explanation of a Linac, found an awesome inspiring video on medical engineering, still worth though! Thanks a lot!
+Daniele Borando Thanks, Daniele. We're happy we could help.
Can i use the video in one of my presentation ?

Bestest explanation dat could ever b had !!! Its vei realistic ,amazing..☺
Amazing work.
Great video. Lets me know what to expect when undergoing radiation treatments for brain cancer.
Thanks for the video...clear and understandable
The Society for Applied Microwave Electronics Engineering & Research (SAMEER) MEiTY exchanged MoU on Magnetic resonance imaging (MRI) and technology transfer of Linear Accelerator with industry.
About Linear Accelerator or LINAC
It’s the device used for external beam radiation treatments for patients with cancer.
It uses microwave technology to accelerate electrons which collide with a heavy metal target to produce high-energy x-rays.
Then the high-energy x-rays are directed to the patient's tumor to destroy cancer cells
Thank you so much, very understandable explanation...
So helpful! Thank you!
Thank you so much.
Excellent presentation
1:40 - The thermionic effect, very similar to how a vacuum-tube version of a diode works. A diode is also called a thermionic valve.
Why aren’t more patients offered this treatment?
Very nice and simple presentation
Wow! This video is very interesting. Recently, I study about LINAC. And I watch this video about its application. Thank you for providing this information.
Great video as i am undergoing radiation theraphy.
The best Exaplaination
Thanks for this wonderful video... I'm currently recieving radiation treatment and as someone else said in the comments I feel much better knowing how this thing works. Also just curiosity as I have an engineering background. Amimation is superb and the narrator is great with her clear voice.
nice video presentation.very informative.thank you!
Thank you so much! The video is very great!
thanks for the info
Thank you, still helping out 10 years later:)

Thank you 👍
Good information for students of Medicine
Does anything here remind you of the train in the Nation of Wakanda? If "yes", you are observant. This presentation is very accurate and very easy to understand for a lay person. As a certified Radiation Therapy Technologist,, and an Engineer, I strongly recommend.
This video rly helped with my physics exam - on my final year now to become a radtech!
Thanks for explaning
Thank you
great and unique
excelente video informativo
I remember doing a project on this in 9th grade. Memories
Very well made video, with excellent explanations. What is the maximum delivered radiation power at the treatment site?
Thank you so much
Well explained and animated. Thank you. :)
You're very welcome!
gud presentation...it is a gud presentation to know the valuable information about the machine working...
thank You
I know I'm going to get some hate for this. But essentially it looks like it's a highly advanced CRT (like an old school TV) that has a cavity magnetron (like you find in a magnetron from a a microwave) pumping RF into it. But instead of phosphors at the end its tungsten (like in a enhanced radiation nuke)
CRT is an accelerator
Thank you......
machine of elegant design
how obtain the schematics diagrams of-The apparatus ??
I'm in LA5, James Cook University Hospital, UK, at this moment
Interesting to see the mechanics of the machine
Wow it boggles the mind how well they can deliver the correct beam and power.
Oh I start on December 17th 2020 9 weeks 5 days a week for prostate cancer
How wonderful
What kind of program you used to realize this animation?
Fascinating
Hello! Can someone explain to me what would happen if this specific machine has a general failure in the LINAC, also in the backup center, and they find lost IP directions?
Nice video. I think I know where the idea came for this resource ;)
where
1st of all gamma radiation consists of high energy photons. It's true that healthy cells are more sensitive to radiation than cancerous cells. But they have very different recovery rates. That means that if these different types of cells take a sublethal radiation dose the healthy cell will recover faster than the cancerous cell. That's why we do radiation therapy in sessions.
awesome
what is the enrgy consumption of this machine?
Love This video... I am a BMET 3 and I also work High Explosive Detection Cat Scans at EWR with aspirations of working on these systems one day.
Please let me know the treatments number required to treat prostrate cancer.
Why did I spend 9 grand on lectures when I could've watched this and bought a book?
We're glad you learned from this. Thanks.
What book do you recommend?
@@0hold Linear Accelerators For Dummies.
@@TheSarcasticEngineer Thank you!
@@TheSarcasticEngineer Thanks! Can you provide me the link to the book? Could be from any website, it's just that I couldn't find the book online
and let me be clear. All the above apply to radiotherapy with photons (X-rays and γ-rays). When it comes to radiotherapy with hadrons (protons, neutrons, heavy ions or even pions) the process differs a little bit.
workded on versa HD for two months
these informations are helpfull but i need a simular articul or pdf that explain the same thing if you might help me and thank you
Amazing
thanks. It is nice.
Why is simulation the most critical and challenging process in preparation
for radiation therapy?
Thanks
