A method of monitoring motion of an anatomical feature within a subject's body comprises the steps of providing a time series of subject images of a region of the subject's body comprising the anatomical feature, providing a plurality of reference images of the region of the subject's body, determining a displacement of the anatomical feature in each subject image using the plurality of reference mages, and monitoring motion of the anatomical feature based on the displacement of the anatomical feature over the time series of subject images. The plurality of reference images comprise a range of projection angles around an imaging axis and perpendicular to the imaging axis through the region of the subject's body. A computer program product for monitoring motion of an anatomical feature within a subject's body is also provided. A method of delivering therapy to a subject and a therapy delivery system is also provided.
