METHOD AND DEVICE FOR CHECKING AN IRRADIATION PLANNING SYSTEM, AND IRRADIATION SYSTEM
First Claim
1. A method for monitoring an irradiation planning, the method comprising:
- providing an irradiation planning data set that is created for irradiating a moving target volume;
providing a motion signal that simulates a motion of the target volume;
irradiating, using an irradiation system, a phantom using control parameters stored in the irradiation planning data set and the motion signal, the phantom being configured for detecting a dose distribution deposited in the phantom during or after the irradiation;
ascertaining the dose distribution deposited in the phantom;
calculating an expected dose distribution on the basis of parameters that are related to the control of the irradiation system during the irradiation; and
comparing the ascertained dose distribution deposited in the phantom with the calculated expected dose distribution.

Abstract
The invention relates to a method for checking an irradiation installation in which a dose distribution is deposited in a target object by means of a treatment beam, said method comprising the following steps: an irradiation planning data record optimised for the irradiation of a moving target volume is provided; a movement signal that reproduces a movement of the target volume is provided; a phantom is irradiated, said phantom being formed for detecting a dose distribution deposited in the phantom during or after the irradiation, using the control parameters stored at the irradiation planning data record and the movement signal; a dose distribution deposited in the phantom is determined; a dose distribution to be expected is calculated on the basis of parameters that are related to the control of the irradiation installation during the irradiation; and the determined dose distribution deposited in the phantom is compared to the calculated dose distribution to be expected. The invention also relates to a corresponding device and an irridation installation comprising such a device.
