Confirmation of a speculation concerning average tissue-air ratio determinations for rotational Co-60 radiation therapy treatment planning
- 1. Department of Radiological Sciences, University of Oklahoma Health Sciences Center, Oklahoma City
Description
The question of the number of radii which are necessary to accurately determine the average tissue-air ratio (TAR) to be used in 60Co rotational radiation therapy treatment planning was studied using actual patient contours. It was found that 12 radii adequately determine the average TAR for clinical purposes
