I have received some messages from DS users that makes me want to clarify this issue.. hang in there for some details (it is really interesting)

1) A newer method of delivering radiation is stereotactic FOCUSED radiation
2) These include a linear accelerator based system: Gamma Knife, X knife, or Cyber knife 3) CYBER KNIFE is a robotic arm attached to a linear accelerator.
3) These stereotactic (precise positioning in three-dimensional space) methods of radiotherapy most commonly involve a single treatment with delivery of a high dose of radiation to a small focused target resulting in decreased radiation exposure to the brain, particularly to the temporal and frontal lobes.

Hope this helps
Stereotactic radiotherapy is a very interesting emerging part of medicine

" Thanks Dr.O. It is very confusing. We were considering this and when we asked our radiology oncologist---she said we has already done it. But the different names are confusing. I am also wondering about cryoablation for spinal tumors for palliative treatment for pain relief. Joan "
