Abstract: Provided is a computer-implemented medical method of irradiation treatment planning that includes an algorithm, which calculates irradiation treatment plans and at the same time considers the combination of the deliverability of the calculated RT plans, the relevancy of the calculated RT plans, and a reasonably distinctiveness between said calculated plans regarding their respective 3D dose distribution. The method automatically calculates and automatically pre-selects some of the calculated plans in steps S1 to S4, which can then be provided to the user. Moreover, in step S5 the method provides a beneficial way of automatically grouping together plans, such as by sorting the calculated and pre-selected plans. By visualizing these automatically calculated, pre-selected and grouped plans in a particular way to the user, the final plan selection by the user is facilitated in a fast, reliable and medically safe manner.

Abstract: The present application provides an initial, or first, packed arc setup to be compared with predefined arc setup constraints. These predefined arc setup constraints at least constrain the number of patient table angles per target volume, constrain the number of times the gantry moves along one arc per table angle, constraint the sum of gantry span per metastasis over all arcs, and constrain the minimum table span. Based on the result of the comparison between the first packed arc setup with the predefined arc setup constraints a second arc setup is automatically suggested. The automatically suggested second arc setup may then be compared with the first one by calculating a score for both setups. Several iterations of such a method can be carried out based on the comparison between an arc setup and the following, subsequent arc setup in the iteration.

Abstract: Disclosed is a computer-implemented method of determining a treatment plan, encompassing acquiring patient image data, acquiring target data describing targets, acquiring position data describing control points which define one or more arcs, and determining target projection data which describes outlines of the target in a beam's-eye view. Margin data is acquired. For the outlines, margins are applied to determine auxiliary outlines. Beam shaping device data is determined describing configurations of the collimator leaves so that irradiation of the auxiliary outlines is enabled. Based on these configurations, the irradiation amount is simulated for voxels of the patient image data. Constraints to be fulfilled by the treatment plan may be set. Configurations of blockings, arc-weights and margins are proposed. Only different combinations of these parameters are proposed while additional possible parameters are neglected. An optimization algorithm is used to minimize an objective function. The best configuration is selected as the treatment plan.
