An indigenous microprocessor controlled Radiation Field Analyzer has been in use for the last one year in this hospital. It has completely replaced the laborious manual procedure of beam data collection. This paper describes the improvements carried out in the mechanical system for the detector movement, the on-line data acquisition and beam data analysis software developed for an IBM compatible personal computer and the results of the measurements carried out on teletherapy units. Beam profiles and central axis depth dose measurements for open, wedge and shaped beams carried out on teletherapy units and the isodose curves generated with these data are also presented in this paper.
