Abstract

The present invention relates to positioning a patient's body part including a target relative to an imaging device that generates a radiation beam directed towards the target. Geometry data is received that describes the geometry of at least one structure located in the field of view of the imaging device. Tracking date is received that describes the spatial location and/or orientation of the at least one structure within the field of view of the imaging device. Position data is determined that incorporates the geometry date and the tracking data. The position data describes whether the location and/or orientation of the at least one structure with respect to an image trajectory is desirable. Repositioning data is determined that describes a desired location and/or orientation of the at least one structure with respect to the image trajectory. The repositioning data is output to allow repositioning of the at least one structure.
