Examination of the consistency and accuracy of computerized brachytherapy dose predictions
Four brachytherapy test cases were sent to representatives of commercial and non-commercial, computerized radiation oncology treatment planning systems. Four commercial systems are represented herein. The non-commercial, state-of-the-art systems represented are (in alphabetical order) BRACHY, ISODOS and RADCOMP. Mutual comparisons were made to examine consistency and a comparison with experimental measurements around a single source was made to examine accuracy. The systems represented are most consistent within 5 cm from the center of a single source, and within rays from the center making angles of greater than or equal to 20/sup 0/ relative to the source axis. Taking into account tissue absorption and scatter, the spatial uncertainty in the location of a particular isodose rate value is less than or equal to 0.7 mm for commercial systems and less than or equal to 0.5 mm for non-commercial systems.
