Problems solved by technology

[0004] Especially in irradiation methods in which several irradiation doses are to be delivered consecutively at different positions in the target volume, it is difficult to achieve the desired uniform dose distribution in the target volume if the target volume moves during irradiation

Embodiment Construction

[0079] figure 1 A schematic diagram of the structure of the particle therapy device 10 is shown. The particle therapy device 10 is used to irradiate an object 14 mounted on a positioning device 12 with a beam of particles 16 —labeled below as particle beam 16 —. In particular, tumor-bearing tissue of a patient is irradiated with a particle beam. The particle beam device 10 is likewise provided for irradiating non-living objects 18 , in particular water phantoms 18 . Irradiation of the water phantom 18 is performed, for example, before irradiating the patient 14 and / or after the patient 14 has been irradiated, for checking and validating the irradiation parameters. It is also conceivable for research purposes to irradiate other objects with the particle beam 16 , in particular test devices, such as cell cultures or bacterial cultures. In all cases, moving or stationary objects 14 , 18 may be involved.

Abstract

The invention relates to a device for determining the control parameters for an irradiation unit, by means of which a number of radiation doses are serially administered to differing target points in a target volume. The device comprises an input device, for recording a target region and the movement of the target region and analytical unit for determining control parameters to control a beam such that, by means of the control parameters a beam may follow the movement for the target region and administer a defined dose distribution to the target region, wherein the analytical unit is designed that on determining the control parameters at least one first selectable control parameter is determined such that the beam only follows the movement for the target region orthogonal to the beam direction or on determining the control parameters at least one first selectable control parameter and a further control parameter representing an energy modulation for the beam are determined, wherein the determination for the at last one first control parameter and the further control parameter occurs taking into account the movement following in the beam direction.

Description

technical field [0001] The invention relates to a device and a method for determining control parameters for an irradiation installation. Such a device or method is used in particular in the context of particle therapy, for example in the context of treatment planning, in which control parameters are calculated in the preparation phase of the irradiation, which allow subsequent irradiation according to a specific predetermined Specifies the subject to be irradiated. Furthermore, the invention relates to an irradiation device and an irradiation method. Background technique [0002] Particle therapy is an established procedure for the treatment of physiological tissues, especially neoplastic diseases. However, the irradiation methods used in particle therapy are also used in non-therapeutic areas. This includes, for example, research work, i.e. product development, within the scope of particle therapy performed on non-biological organ models (Phantom) or objects, irradiatio...
