title: Dose uniformity from a computerized three-dimensional tissue compensating system.
abstract: A verification of dose uniformity of the Huestis Compu-Former, a three dimensional megavoltage tissue compensator, is presented. Tissue compensators were built for three different anthropomorphic phantoms: a head and neck, a mantle, and a breast. Film densitometry was used to evaluate the effectiveness of the tissue compensators by comparing isodose curves generated for a compensated and an uncompensated field. Evaluation of the isodose distributions for the three regions confirmed the use of the Compu-Former as a reliable tissue compensating system.
