摘要： A method is disclosed for automatically determining the rectum distance in a patient's colon, the path in the colon between a selected site, preferably a lesion, and the rectum being determined by processing 3D image data records. At least two 3D image data records are recorded with the patient being differently positioned. Further, the path between the rectum and selected site is determined from the common perusal of the at least two 3D image data records.

摘要： A method and CT system are disclosed for recording and distributing whole-body CT data of a polytraumatized patient. In at least one embodiment the method includes producing a whole-body topogram including division and assignment of z-coordinate regions of the whole-body topogram to different body regions; performing a whole-body CT scan with the recording of CT raw data; assigning the CT raw data to the different body regions; reconstructing CT image datasets on a computer of the CT system; and sending only body region-specific CT image datasets to a number of remote workstations operated by technical specialists.

摘要： A method is disclosed for determining a 2D contour of a vessel structure imaged in 3D image data for a first slice plane of the vessel structure, wherein the 3D image data was generated using a medical imaging system and has a multiplicity of image voxels which are all assigned a respective image value. In at least one embodiment, the method includes providing 3D image data; determining a multiplicity of first initial 2D contours of the vessel structure, wherein the first initial 2D contours in the 3D image data are determined for slice planes of the vessel structure, which planes are arranged orthogonally in respect of a central line of the vessel structure and spaced apart from one another along the central line; determining a first initial 3D contour from the first initial 2D contours; determining a smoothed second 3D contour by applying an active 3D contour model to the first initial 3D contour; determining a second initial 2D contour as a slice through the smoothed second 3D contour including the first slice plane; and determining the 2D contour by iteratively fitting the second initial 2D contour to that vessel structure imaged in the 3D image data which results for the first slice plane.

摘要： 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.
