Individualized Perspex treatment shell technique with fixed treatment distances from irregular surface topography for HDR selectron tubes was developed for irradiating recurrence along the surgical scars or skin nodules of breast. Simulation technique was evolved to localize pellet sources for generating data input for computerization of dosimetry. Selectron of prescription planne and the optimum orthogonal radiographic views for identification of each individual pellet were the problems surmounted. Computed dose rate distributions in different planes were then used for dose prescription. HDR dose-time schedules employed were evolved through a normalization constant for LDR-HDR equivalence derived from a modification of radiobiological evidences projected by Turesson and Notter (1979, 1984) and Morrison (1979). Fifteen patients treated by this dose time relationship facilitated the evolution of a HDR-surface application system by the present investigators.
