Thanks for your opinion.
I am leaning towards the mri guided sbrt over cyberknife due to the mri function. It appears that the cancer center I go to is not doing adaptive radiology with each fraction. I have been in contact with a patient on another site who had to convince the RO at this site to use the mri linac daily for his prostate cancer. I asked AI to prepare a list of mri linac sites. I would have to validate each site listed prior to posting. Looks like I would have to travel out of florida to get mri guided. There are cyberknife experts in my area though that have done cyberknife for PC for 20 and 30 years.
