Abstract:
1. A method for controlling the dose application during irradiation of a moving target volume in a body with an energy beam using a scanning method, the method comprising creating an irradiation plan including a plurality of grid positions (i, 1<=i<=N) of the target volume for one or more irradiation cycles (j, 1<=j<=J), wherein N and J are positive integers; defining a grid-position-dependent nominal particle fluence in the irradiation plan for the irradiation of each of the grid positions; capturing a motion of the body during the irradiation in order to determine a motion of the grid positions during the irradiation; and successively scanning the individual grid positions with the energy beam using a particle energy and a particle fluence that are controlled as a function of the grid position, so as to apply a grid-position-dependent dose at the corresponding grid position, the scanning including: steps i1) through i4) being carried out for the plurality of grid positions (1<=i<=N).
