Abstract
A film dosimetry system for use in calculating the surface dose delivered by a CT [computed tomography] scanner was described. Film was wrapped around a cylindrical water-filled phantom, and dose distribution was recorded. This system was easier to use than thermoluminescent dosimetry (TLD) and provided a detailed map of dose distribution. Comparison with TLD measurements for a variety of CT scanners indicated that an accuracy of .+-. 15% can be achieved using this system. Dose distributions obtained with several scanners were shown.This publication has 0 references indexed in Scilit:
