A method for generating a volume-viewing image on the basis of three-dimensional image data of the interior of a body generated by way of a medical imaging system is described. In at least one embodiment, a plurality of different functional structures of the body are first of all segmented in the three-dimensional image data. Moreover, structure selection data for fixing functional structures to be visualized is determined. Then, at least one volume-viewing image is generated from the three-dimensional image data on the basis of the segmented functional structures and the structure selection data and the image is output. Moreover, in at least one embodiment, an image-processing system to carry out at least one embodiment of the method is described.

Method and image-processing system for generating a volume-viewing image of the interior of a body

A method is described for structurally individualized simulation of the introduction of a wall support element into a section of a tubular structure. To this end, image data of the interior of the section of the tubular structure are provided. A start point and an end point of the section of the tubular structure are then determined, and a lumen and a profile line of the tubular structure are determined between the start point and the end point. Furthermore, an individual elastic structure model for the section of the tubular structure is identified by adapting a tubular elastic initial model to the section of the tubular structure on the basis of the identified lumen and the profile line, and a tubular elastic wall support element model which is positioned inside the individual structure model is provided. In at least one embodiment, the wall support element model is then virtually expanded stepwise, a check for collisions between the wall support element model and the individual structure model being carried out in each expansion step. At the positions where a collision is identified, the wall support element model and the individual structure model are modified at least locally while taking into account the elasticity of the individual structure model. A method for driving an image display device, by using such a simulation method, and a simulation device are furthermore described.
