The method involves applying a defined radiation dose in a sample body (29) e.g. polymethylmethacrylate phantom, and/or at a predetermined site in a treatment chamber. An activity generated by the defined radiation dose is measured with a positron emission tomography (PET) scanner. The PET scanner is calibrated as a function of the measured activity, where a response performance of detector elements of the PET scanner, local resolution and local coding of the PET scanner are calibrated as the function of the measured activity. An independent claim is also included for a radiation therapy device comprising a radiation source. |
