[Use of the EC 1010 computer to calculate dosimetric parameters for irradiation procedures in gamma teletherapy]

An ever growing flow of patients requires a good deal of time for the planning of irradiation procedures of patients and causes errors during manual calculations. A small-size computer EC 1010 is proposed for the calculation of dosimetric parameters of irradiation procedures on gamma-beam therapeutic units. A specially designed program is intended for the calculation of dosimetric parameters for different methods of moving and static irradiation taking into account tissue heterogeneity: multifield static irradiation, multizone rotation irradiation, irradiation using dose field forming devices (V-shaped filters, edge blocks, a grid diaphragm). In addition to the main calculated values, the listing contains in a suitable form all necessary information: the patient's name, date of calculation, a unit type for irradiation, irradiation procedure parameters. The computation of output parameters according to each preset program of irradiation takes no more than 1 min. The use of the computer EC 1010 for the calculation of dosimetric parameters of irradiation procedures gives an opportunity to considerably reduce calculation time, to avoid possible errors and to simplify the drawing up of documents.
