Abstract: A method includes determining a position of a local coil, a coil position, and a position of a body part of a patient, a body part position. Spacing between the coil position and the body part position is determined. An optimized MR sequence is determined. Based on the determined spacing between the coil position and the body part position, it is checked that in a subsequent MR examination of the patient, a predetermined loading threshold value (e.g., an SAR value) is not exceeded. The optimization of the MR sequence thus takes place under the boundary condition that the loading threshold value is not exceeded.

Finally, the synthetic 3D model image or a partial volume of it is visualized.

In the method, a starting point is initially set in the 3D image data, and at least one known anatomically significant point and/or at least one known anatomically significant surface are/is identified in the 3D image data. Subsequently, proceeding from the starting point the structure is subsequently segmented pixel by pixel with the aid of a multiplicity of segmentation steps in such a way that an instantaneous distance is determined automatically relative to the anatomically significant point and/or to the anatomically significant surface in each segmentation step. Further, segmentation parameters and/or a selection of adjacent pixels for continuing the segmentation are/is established as a function of the distance, taking account of a model topology. The method enables an accurate and reliable segmentation of the anatomical structure.
