摘要:
A system for accurately detecting a patients movement during imaging procedures includes a camera for providing a stream of camera images of a part of a patients exterior and a fiducial element mountable on part of the patients 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 patients exterior. In addition, the fiducial element and the part of the patients exterior are provided with substantially equal outer in-plane dimensions.
