Abstract: Method for determining a spatial distribution of element size values for geometric basic elements of a network display from a digital display of an object for a simulation of the object, wherein the network display contains interconnected geometric basic elements. The method including: determining a digital display of an object; determining, for at least one position of the digital display, at least one local maximum limit for the element size values that depends on at least one local geometric property in an area surrounding the position: determining, for the digital display, a predefined spatial distribution of an upper limit, independent of the maximum limit, for the element size values and a predefined spatial distribution of a maximum spatial change in the element size values; and determining a spatial distribution of element size values for the digital display based on the maximum limit, and the two predefined spatial distributions.

Abstract: The invention relates to changing a model geometry of an object by providing a target geometry and a model geometry for the object; using the model geometry to provide an actual geometry of the object; determining whether there is a deviation between the target geometry and the actual geometry; and changing the model geometry into a modified model geometry on the basis of the determined deviation; wherein determining results in a first non-rigid mapping, if there is a deviation, that associates two geometries with each other by using a parameter set and describing the determined at deviation, or at least the changing is carried out by a second non-rigid mapping that associates two geometries with each other by using a parameter set. Thus, correct values are provided in the event of deviations and deformation, and the corrected values reduce the effort in finding a model geometry for producing an object.

Abstract: A radiotherapy treatment plan for irradiation of an object to be irradiated is determined. The object to be irradiated includes a number of irradiation areas and the object to be irradiated is irradiated with a number of beams from different directions. The method includes determining a number of total dose conditions. One of the number of total dose conditions is assigned to a respective one of the number of irradiation areas. The method further includes determining a number of single beam dose conditions. One of the single dose conditions is assigned to a respective one of the number of beams and a respective one of the number of irradiation areas. The method also includes determining irradiation parameters for the number of beams as a function of the number of total dose conditions and the number of single beam dose conditions.

Abstract: A method for determining a 4D plan for carrying out intensity-modulated radiation therapy of a target volume subject to irregular periodic motion, with a radiation therapy apparatus is provided. The method includes selecting positions of a radiation source. The number of positions is selected to be identical in all 3D radiation therapy plans. The method also includes selecting a number of respective aperture settings assigned to a respective position of the radiation source to be identical in all 3D radiation therapy plans. A geometrical, temporal, and/or dynamic restriction that restricts a change of the aperture from one aperture setting to another aperture setting is predetermined, and the 3D radiation therapy plans are determined such that the 3D radiation therapy plans fulfill predetermined restrictions for aperture settings in each case.

Abstract: A device for determining control parameters for a particle irradiation system that deposits different dose values at different target points in a target volume through the selection of sampling points by a particle beam is provided. The device includes an input for receiving information relating to a predefined dose distribution via target points, and a determination component for determining a particle number distribution that is to be deposited during the irradiation via sampling points. The determining takes place using the predefined dose distribution and a variable, which takes into account differences in the particle number distribution between particle numbers of different sampling points.

Abstract: The invention relates to the quantitative analysis and/or visualization (virtual or real) of moving processes and to the detection, description, correction and the comparison of global movements inside the image space. The invention particularly relates to a method and device for precisely and, while being limited to few parameters, quantitatively describing the global and local movement occurring in the image space and for the single representation of the movement of the quantitative parameters with regard to the image space. A rough to fine recording and a detection of and compensation for global movements occurs whereby enabling a tracking and a corrected visualization. The detection of the movement, which corresponds as precisely as possible to the real movement occurring in the image space is effected by a splines a plaques minces recording technique that enables the number of movement parameters to be kept low. A fully automatic execution of all partial steps is made possible.
