[Control of the main radiation parameters of a gamma teletherapy apparatus]
Abstract:
In radiotherapy a dosimetric method is used nowadays to control the magnitude of the radiation axis deviation from the isocenter (RL) of a gamma-beam therapeutic apparatus (gamma BTA). However, the use of the method requires special costly equipment. Besides, it is fairly laborious. The dosimetric method does not permit the measurement of the distance between the isocentre and the virtual source (DISvirt) A gamma-metric method of the RL and DISvirt control in the gamma BTA is described. It is based on the photogammametric treatment of a gamma-picture of a special test object. The method is marked by high accuracy and safety. In addition, the gamma BTA can also be used in operation of accelerating therapeutic units.
