Abstract
Methods and systems are disclosed herein for improved safer planning support during interventional procedures for inserting stents into a hollow organ of a patient by a guide device. One method includes: providing or recording a three-dimensional image data set of the hollow organ in a first position; segmentation or providing a segmentation of the three-dimensional image data set; providing or recording a two-dimensional image of the guide device introduced into the hollow organ; overlaying the three-dimensional image data set with the two-dimensional image; determining at least one corrected position of one or more section(s) of the hollow organ respectively using the overlaying of the three-dimensional image data set with the two-dimensional image; and determining the respective deformation energy of the hollow organ in the section(s) for the case of removal of the guide device using the previously determined corrected position compared to the first position.
