ABSTRACT:
A volume phantom for radiation therapy verification employs film held in a spiral configuration within a equalizing ring of attenuating material. The ring provides improved uniformity in radiation measurement and may be extended, for example, to a hemisphere to provide improved modeling and simulation of treatments in the region of the head.
