1. A method for determining a biopsy position, comprising: receiving an image data set of an examination volume via an interface, the examination volume including a tumor; segmenting a tumor region in the image data set via a computing unit; determining a texture distribution of the tumor region via the computing unit, the texture distribution assigning a respective texture parameter to respective image points in the tumor region and each of the respective texture parameters being based on a spatial distribution of first intensity values of the image data set; and determining, via the computing unit, a biopsy position within the tumor region by applying an optimized position-determining algorithm to the texture distribution, the optimized position-determining algorithm being based on training texture distributions and first training positions, respective ones of the first training positions being assigned to respective ones of the training texture distributions.
