Dosimetry in teletherapy in Cracow

A dosimetry procedure is described used as standard by the Institute, based on the use of an automated water phantom system for beam data acquisition and a dedicated minicomputer system for individualized treatment planning. An approach is also characterized to fractionated radiotherapy based on the time-dose and fractionation (TDF) concept introduced by Goitein. The program for iso-TDF distribution assessment considers both electron beam and 60Co radiation parameters. An example is shown of the application of the program in abdomen treatment using the moving strip technique. Some constraints are outlined of routine practice. (L.O.). 10 figs., 2 tabs., 13 refs
