1. A method for deformation simulation of a hollow organ that is deformed by an introduction of a medical instrument or a medical object, the method comprising:
providing a pre-trained machine-learning algorithm, wherein the machine-learning algorithm is pre-trained by a plurality of known pairs of recordings from a first three-dimensional medical recording of an undeformed hollow organ and its surrounding tissue and a second three-dimensional medical recording of a hollow organ and its surrounding tissue deformed by a medical instrument or a medical object;
acquiring a three-dimensional medical recording of the hollow organ with surrounding tissue, wherein the three-dimensional medical recording was recorded before the introduction of the medical instrument or the medical object;
segmenting or acquiring a segmentation of the three-dimensional medical recording of the hollow organ;
forming or acquiring a three-dimensional model of the hollow organ;
providing information about the medical instrument or the medical object introduced or to be introduced; and
simulating, using the pre-trained machine-learning algorithm, a deformation of the hollow organ to be expected or brought about by introduction of the medical instrument or the medical object on a basis of the segmented three-dimensional medical recording of the hollow organ and the surrounding tissue and the information about the medical instrument or the medical object.
