A method for controlling a medical imaging examination of a subject, wherein the medical imaging examination comprises performing a medical imaging scan of a body region of interest (34, 44) of the subject using a pre-selected scan protocol, wherein the medical imaging examination is performed using a medical imaging system having a gantry, a patient table which is moveable with respect to the gantry and on which the subject is positioned, a control unit for controlling the medical imaging scan and having access to an image sequence of the subject acquired by a camera, and wherein the method comprises the steps of (a) receiving an image sequence (30, 32) of the subject from the camera during the medical imaging scan; (b) receiving the current position and/or velocity of the patient table during the medical imaging scan; (c) performing a motion tracking analysis of the received image sequence to extract a motion model, wherein the motion tracking analysis and/or the motion model is tailored to the body region of interest and takes into account the current patient table position and/or velocity; (d) analysing the motion model to detect subject motion and, for example if the detected motion is above a pre-determined threshold, adapting the medical imaging examination to the detected motion and/or issuing an alert to make the subject and/or an operator of the medical imaging system aware of the detected motion. wherein the medical imaging examination is performed using a medical imaging system having a gantry, a patient table which is moveable with respect to the gantry and on which the subject is positioned, a control unit for controlling the medical imaging scan and having access to an image sequence of the subject acquired by a camera, and wherein the method comprises the steps of (a) receiving an image sequence (30, 32) of the subject from the camera during the medical imaging scan; (b) receiving the current position and/or velocity of the patient table during the medical imaging scan; (c) performing a motion tracking analysis of the received image sequence to extract a motion model, wherein the motion tracking analysis and/or the motion model is tailored to the body region of interest and takes into account the current patient table position and/or velocity; (d) analysing the motion model to detect subject motion and, for example if the detected motion is above a pre-determined threshold, adapting the medical imaging examination to the detected motion and/or issuing an alert to make the subject and/or an operator of the medical imaging system aware of the detected motion.
