title: A modified dose monitoring system in remote afterloading therapy of carcinoma of the uterine cervix using semi-conductor dosimeter.
abstract: A dose monitoring system in high dose rate intracavitary remote afterloading therapy of carcinoma of the uterine cervix using semi-conductor dosimeter was developed in July 1979 at our department. During early experience with the above system, extremely high values of mgh as well as high doses to rectum and bladder were encountered in the cases with poor local anatomy or unsuitable application. Solving this problem, such limitations as to the mgh as well as point-A dose were added to the computerized rapid processing system for the pretreatment dose calculation and correction of the treatment parameters to adjust the point-A dose to within +/- 5% of the planned dose. In the majority of the cases treated with Ralstron, this modified dose monitoring system brought considerable success in the optimization of point-A, mgh, rectal and bladder doses, in a simple manner.
