I doubt that much adaptive planning is taking place with mri/prostate. And I have plenty of experience with calypso to know the intrafraction motion is not signficant. (Extreme drift is few and far between and very short lived. Beam was almost never stopped)
Did Dan the man buy one of these magnificent machines? Brachytherapy (LDR or HDR ) makes intrafraction motion moot. Charlatanism
MRI linacs are also the proton problem, just on a smaller scale... 3-4x the cost of a Linac without any data to support routine use
You're hilarious. We're going to continue to see proliferation of protons and MR-Linacs and if anyone questions why:
Which when anybody says that we have to refute it strongly with data (studies) that did compare. It’s one of rad onc’s most insidious lies.
"You allow your patient to wear deodorant during breast radiation? You clearly own stock in the deodorant companies. Or bill the deodorant gel as bolus and a complex treatment device. I smell a rat!"
When early to mid career academics, who have extensive experience with these tools, require them for consideration of a next job, I'll feel confident that there is real value here.
Ah, my friend! Let me introduce you to my new product:

Magnetic resonance imaging-guided stereotactic body radiotherapy for prostate cancer (mirage): a phase iii randomized trial - PubMed
Clinicaltrials.gov identifier: NCT04384770. Date of registration: May 12, 2020. https://clinicaltrials.gov/ct2/show/NCT04384770 PROTOCOL VERSION: Version 2.1, Aug 28, 2020.
The primary endpoint is rather ...amusing. The trial wants to show that MR-Linac treatment will reduce acute grade >1 GU toxicity by 14%.
I find no words to stress out the vast importance of this endpoint. 😛 😛 😛

If given half a chance, I would happily compare my collections for a 44 fraction VMAT prostate against a Sloan/DFCI/Anderson SBRT prostate, and MOST CERTAINLY against an MRI-guided SBRT prostate at UCLA.
Agree. Need wordle thread?
whoa back story?
