TomoTherapy is a registered trademark for a instrument which combines IMRT and CT to better target the area to be radiated, and to reduce damage to surrounding tissues. It is used particularly for cancers in areas where important organs/tissues lie close to the tumor, e.g. prostate, brain, head/neck. Most of the top HNC centers have or are getting TomoTherapy -- Johns Hopkins, Sloan-Kettering, etc. It is considered the next development up from IMRT.

We are going up Tuesday to consult with rad onc at Hopkins (Dr. Lee) and to find out more about TomoTherapy which is on-line there, and will post more when we return.

Btw, the JH web site has a page on TomoTherapy.
