"Borrowed these directions from another one of Brian's posts. He describes finding things better than I do" Thanks Brian - hope you don't mind.
Here is one link in the site for IMRT radiation
http://www.oralcancerfoundation.org/facts/imrt_radiation.htm But you can always go to the word “search” on the bottom of all of the navigation bars and type in words that you want the site's search engine to find in the site for you… in this case I typed in IMRT. You can also clink on "site map" on all of these same navigational pages, and you will see a complete list of page links of everything that is currently in the site. Lastly, the search engine for the message board is a stand alone feature. If you want to search the hundreds of postings on the message board for something, the word search appears under the message boards title on the first page of the message board.
