I have lots of anxiety about radiation I received from CT scans. abdomen pelvis. 35 age

Finally someone with knowledge on the subject. I really loved the explanation on the regular daily DNA breaks vs those that occur after radiation exposure. Sub well deserved 👍

😂

Surprising!!

Wow

Just fantastic - thank you so much! So helpful.

This has to be one of the best explained and most concise videos I've watched on this topic. You really should make more videos. Thank you sir - it's much appreciated.

Don't agree with. This

It's scary to consider how many researchers were badly injured by x-rays before they knew how dangerous they can be. Around 1950 I was in a shoe store in Dallas where they had a machine to x-ray your feet to show how shoes fit.

Good presentation! And it blinked.

great video !

Very interesting!!

Sounds like a good life mission. Nice discussion and very informative

Prezado Doutor! Boa noite! Quais os riscos para uma Radioterapia no Nono Arco Costal, metastase de Cancer de Mama lado direito? Pode prejudicar o pulmão? Agradeço sua atenção! Simone - Brasil. Dear Doctor! Goodnight! What are the risks for Radiotherapy in the Ninth Costal Arch, right sided Breast Cancer metastasis? Can it harm the lungs? Thank you for your attention! Simone - Brazil.

nothing about cobalt 60? I was treated with at age 12, c.1970 & age 60 c. 2023... know lots of people, but can't find a word about it

there is same mistakes in those interpolations

nice

That was a great video. Thanks! Please share videos about proton radiotherapy.

Thank you for making videos again. Keep it up please.

Interesting video, however, as someone who experienced vaginal vault brachytherapy for Endometrial Cancer with 66% muscle penetration. I would have to say, it was more than disturbing to call the Radiation Oncologist's office only to be told, that no, I could not have Radiation Disease, because I was 'X' number of weeks past my treatment dates, so that could not possibly be the case. Obviously,. I was lied to when Radiation Disease can happen at anytime, even years after treatment. Having one's insides literally toasted, comes along with several really nasty issues, that make day to day living seriously challenging. So far, I have tried medication, and having a Metronics Interstim implant, botox injections, and more recently Bulkamid which has proven totally useless for stress incontinence. The risk of incontinence accidents in social situations can be, and is very stressful. To say nothing of the humiliation and distress caused by actually having the vaginal vault brachytherapy procedure, which felt like being raped, as the doctor literally shoved the cylinder into me, without first checking the shape of internal anatomy. To say it was a horrible degrading and humiliating experience would be an understatement. After that, I told him, I would be the one to place the cylinder, which he then custom made for me. After changing my diet from vegetarian to plant-based high fiber, whole foods, low fat, low protein, no processed foods, sugar or alcohol and using filtered water, my beloved Oncologist rates my risk of recurrence at only 3%. She is totally impressed, I also used fasting before, during and after treatment, and lost 40lbs, still need to lose more. In hindsight, I would not have had radiation treatment, though of course, it was recommended at a 7 on a scale or 1-10. The problems I am now left with two years later, are actually far worse than cancer, and impact my life every single day. Next step is likely a surgical mesh, which may or may not work. My advice to anyone considering Radiation Treatment would be to think first, do your research, and be fully informed before ever embarking on something that can impact your life for good or ill, in ways you may not have, in your wildest dreams considered. By the way, my favourite coffee mug at the moment is one from Seattle Opera depicting, Wagner. During my Radiaiton Therapy, I chose to listen to Ballad for Adeline, an Andre Reiu recording, which brought peace to my soul and one of life's most difficult times. A piece the staff treating me also loved, and asked the name of. Truly beautiful!

That's the good educational video :)

Thank you. That was very helpful. so I have a question. I was wondering why in clinical measure PDD at 10 cm and 20 cm and look at the ratio.

Why have you stopped making videos. ??? Your explanation is awesome. Can you make a video on Therma, and kernels. Explaining the basics of it. 🙏

Are we all going to ignore Marie Curie again?

Pls for the scatter factors, a 15 x 15 field gives 1.019 and 1.012 for Sc & Sp respectively. And for the 20x20 cm field size, we have 1.030 and 1.021 for Sc and Sp respectively. So how did you get 1.025 as Sp for your MU calculation

Thank you sir. I would like to talk to you in your inbox

BEST EXPLANATION EVER....GOD BLESS

in the OAF session, the label on the graph is swaped.

Great videos

Thank you sir for the great video. Now what happens if the beams arent equally weighted ???

Please write a textbook for us its so helpful. There are so many med Physicists out there who can not teach despite being competent at their job.

More videos for MU calculations

4.50 pierre curie died in a road accident.

Yeah, I've read that the majority of the DNA damage from ionizing radiation overall is indirect as you mentioned which makes sense given that water is a much bigger (more abundant) target to ionization than DNA itself. en.wikipedia.org/wiki/Radiation_damage#Effects_on_water

Nice presentation sir.

Thank you for amazing videos! So easly understanding 🍀 Everything you posted is so useful! Please share more content. Greetings from Bosnia❤

Thanks for your sharing and very clear it.

Thank you sir

Thank so much for taking your time explaining each step , before this video I was so lost, I looked for medical physics tutors but no luck, Best of luck in your channel. Here is an idea to increase the channel content, what if you can make a video for each chapter on Medical Physics Book i.e Khan’s The Physics of Radiation Therapy

A comprehensive video.

very nice explanation, easy to understand.

Great thank you....sir... can you make video on isodose distribution and related topic

Pl upload more vedioes on radiotherapy like isodose curves and wedge factors wedge angle and planning

Thank you so much I need your presentation please

I want to resolve many exercises about this topic, can you share me a book or pdf?

Hey! how can I to know at wich depth/distance I need to calc the equivalent square field of 20x18? At surface or at isocenter?

As a first year Resident in Clinical oncology, this information is priceless,I truely appreciate it.

Great job Jerimy!

Hi, are you running any course to cover whole subject ? Thank you

Thank you. This is a real great explanation and one of the best I have seen so far.
