1. A computer-implemented method of determining a consensus plane usable for imaging an anatomical body part with a medical imaging device, the method comprising:
acquiring patient image data which describes an anatomical body part of a patient's body;
acquiring planned trajectory data which describes an orientation of a longitudinal axis of an elongate medical device and a position of the elongate medical device relative to the anatomical body part;
determining initial imaging plane data of the medical imaging device based on the planned trajectory data, wherein the initial imaging plane data describes a relative orientation between the orientation of the longitudinal axis of the elongate medical device and an imaging plane of the medical imaging device useable for simultaneously imaging the elongate medical device and the anatomical body part;
acquiring imaging device constraint data which describes a plurality of possible relative orientations between the imaging plane of the medical imaging device and an orientation of the longitudinal axis of the elongate medical device or the anatomical body part;
acquiring orientation condition data which describes a predetermined condition to be met by the relative orientation between the orientation of the longitudinal axis of the elongate medical device and the imaging plane of the medical imaging device;
determining consensus plane data based on the imaging device constraint data and the initial imaging plane data and the orientation condition data, wherein the consensus plane data describes a relative orientation between the imaging plane of the medical imaging device and the orientation of the longitudinal axis of the elongate medical device, which orientation is to be applied for imaging the anatomical body part and the elongate medical device with the medical imaging device; and
acquiring avoidance region position data which describes a position of an avoidance region, wherein the avoidance region is a region in the anatomical body part, wherein the region shall at least substantially not be intersected by imaging radiation during the imaging,
wherein the determining consensus plane data is further based on the avoidance region position data.
