First Claim
1. A method for determining and using an irradiation plan for a particle irradiation system, the method comprising:
- defining a target volume within a test object and a predetermined dose distribution;
determining the irradiation plan in order to apply an energy of a particle beam in accordance with the predetermined dose distribution in the target volume, wherein the irradiation plan specifies a number of particles of a specific energy to be applied at a point in the target volume within the test object; and
irradiating, with the particle irradiation system, the target volume within the test object with the particle beam as a function of the irradiation plan,wherein the irradiation plan is determined as a function of a defined maximum irradiation time at an isoenergy layer in the target volume and as a function of an efficiency factor of the particle irradiation system, the efficiency factor being based on a ratio of a measured intensity of the particle irradiation system to an intensity of the particle irradiation system prescribed in the irradiation plan, andwherein determining the irradiation plan comprises determining the irradiation plan such that the irradiation time is minimized.

Abstract
The device relates to a method and a device (10) for determining an irradiation plan for a particle irradiation unit (20). In the method, a target volume (6) within a test object (14; 18) is irradiated with a particle beam (16) using the particle irradiation unit (20) according to the irradiation plan. The radiation plan is determined in order to apply the energy of the particle beam (16) according to a predetermined dose distribution in the target volume (6), the target volume (6) and the predetermined dose distribution being pre-set. When determining the irradiation plan, irradiation duration is also taken into account, the irradiation plan being determined such that the irradiation duration is as short as possible.
