Claim Text:
1. A method for treatment with a treatment particle beam aimed at at least one target region, planning parameters having associated predetermined parameter values and being for performing the treatment that is to be applied with the treatment particle beam, the method comprising: defining a first predetermined parameter value of the planning parameters, the first predetermined parameter value being for an irradiation of the at least one treatment region, the at least one treatment region comprising at least one target region; ascertaining, based on the first predetermined parameter value, a first probability distribution defining a probability with which a volume portion of the treatment region is enclosed by an isoline or an isoarea, the volume portion being prespecified based on deviations to be expected when carrying out the irradiation; and performing, by a therapy system, the treatment based on at least one of the predetermined parameter values, wherein the at least one predetermined parameter value is controlled in accordance with the first probability distribution so as to control a dose of the treatment particle beam, to form an isoline or isoarea that defines a contour that is a close match with the prespecified volume portion of the treatment region.
