A method for calibrating a positrons - transmit - tomographs a radiation therapy device, as well as on the radiation therapy device

摘要

The present invention relates to a method for calibrating a positrons - transmit - tomographs a radiation therapy device, whereby at least a defined exposure dose is applied in a specimen, in that the generated by the radiation dose activity was determined with the positrons - - emission tomography apparatus is measured and in that the positrons - - emission tomography graph is calibrated with the aid of the measured activity. Furthermore, the invention relates to a for carrying out the method radiation therapy device, which is constructed with a positrons - transmit - tomographs.
