PATIENT MOTION DETECTION IN DIAGNOSTIC IMAGING

Abstract

A device (10), system, method and computer-program product are disclosed for detecting movement of a subject in a diagnostic imaging examination. The device comprises a camera/3D surface scanning system (11) and an input (14) for receiving a trigger to indicate that a current spatial configuration of the subject is to be maintained for the examination. The device comprises a processor (12) and an output (13), in which the processor (12) is adapted for acquiring reference data of the subject using the camera/3D system when said trigger is received, and for acquiring further data of the subject using the camera/3D system after acquiring said reference data. The processor is adapted to compare the reference data, which represents a reference state of the subject at substantially the time that the trigger was received, to the further data, which represents a more recent state of the subject. The processor is adapted to provide output data via said output (13), in which this output data is representative of the comparison of the further data to the reference data so as to indicate movement of the subject with respect to the reference state of the subject.
