INTEGRATED SOFTWARE TOOLS FOR THE CALCULATION IN RADIOTHERAPY

Abstract

To enhance quality and readiness of treatment with radiation at division of radiation oncology, Chulalongkorn Hospital, we have invented the integrated software tools for various calculation in radiotherapy. The program was written on personal computer and Microsoft Access was chosen as a programming environment because of its powerful data- base management, calculation and graphic capabilities. There are several separated modules for each calculation. The modules consist of the radiation isoeffect dose module for radiobio- logical dose calculation, the monitor unit module for double-checking of monitor unit for a linear accelerator, the percentage depth dose module for quick finding of percentage depth dose of single field radiation treatment, the craniospinal technique calculation module, the gap between adjacent fields module, the body surface area module for quick calculation of body surface area, the activity of radioisotope module for calculation of residual activity of radio- isotope after known time interval and tangential breast technique module for calculation in simulation of breast irradiation.
