摘要： A system for accurately detecting a patient's movement during imaging procedures includes a camera for providing a stream of camera images of a part of a patient's exterior and a fiducial element mountable on part of the patient's exterior. The fiducial element is detectable in the stream of images. An image processor is configured to detect a displacement of the fiducial element based on consecutive images including in at least the stream of images and to generate an output signal indicative of the displacement. The fiducial element has an in-plane stiffness which is substantially larger than an in-plane stiffness of the part of the patient's exterior. In addition, the fiducial element and the part of the patient's exterior are provided with substantially equal outer in-plane dimensions.

摘要： The invention relates to a method, a device and a computer program product for tracking a movement of an object or of a person. Tracking the movement of a person or an object by means of electronic video frames is conventional but fails if the person of object experience a sudden significant change in its translational velocity. The suggested method comprises a first step of grabbing a sequence of digital video frames and thereby capturing the object or person. At the same time measurement values of a parameter are obtained, said measurement values being indicative for the movement of the object or person being tracked by the digital video frames. In the next step the video frames are processed by means of processing logic whereby the processing logic uses a block matching algorithm, said block matching algorithm defining a pixel block in a frame and searching for this pixel block within a search area within a next frame and whereby the location of the search area within the next frame is dynamically adapted on the basis of the measurement values. The invention provides the advantage that an electronic processing of digital video frames by means of a block matching algorithm can be carried out even in those cases in which there are large changes in the velocity of the tracked object or person.
