1. A computer-implemented method, comprising:
acquiring initial biomechanical model data which describes an initial biomechanical model of an anatomical body part;
acquiring workflow step data which describes a current step of a workflow of a procedure to be carried out on a patient;
determining status change data based on the workflow step data and the initial biomechanical model data, wherein the status change data describes a change in the patient's status;
determining imaging device guidance data based on the status change data, wherein the imaging device guidance data describes a position at which a medical imaging device is to be positioned;
acquiring model adaptation data which describes an association between the change in the patient's status and an adaptation to be applied to the initial biomechanical model;
determining adapted biomechanical model data based on the initial biomechanical model data and the status change data and the model adaptation data, and
wherein the adapted biomechanical model data describes an adapted biomechanical model which is determined by applying the adaptation to the initial biomechanical model.
