Abstract
A method for calibrating a positron emission tomography scanner of a radiation therapy device is provided. The method includes applying at least one defined radiation dose in a sample body; measuring the activity generated by the radiation dose using the positron emission tomography scanner; and calibrating the positron emission tomography scanner based on the measured activity.
Claims20
A method for calibrating a positron emission tomography scanner of a radiation therapy device, the method comprising:
- applying, using a radiotherapy device, at least one defined radiation dose in a sample body to induce a defined activity in the sample body, the at least one defined radiation dose being applied by irradiating the sample body with a treatment radiation beam of the radiotherapy device;
- measuring the activity generated by the at least one defined radiation dose with the positron emission tomography scanner;
- and
- calibrating the positron emission tomography scanner as a function of the measured activity.

A radiation therapy device, comprising:
- a radiation source that is operable to apply at least one defined radiation dose in a sample body, the at least one defined radiation dose being applied by irradiating the sample body with a treatment radiation beam, the defined radiation dose inducing a defined activity in the sample body;
- a positron emission tomography scanner in at least one treatment chamber, the positron emission tomography scanner being operable to measure radiation activity generated by the at least on defined radiation dose;
- and
- a control unit that is operable to calibrate the positron emission tomography scanner based on measured radiation activity.
