Abstract

Device for displaying a movement of a patient, preferably of a body part being diagnosed or treated by means of radiation. A modulated semiconductor laser (12) generating a punctiform or linear beam is provided, as is an optoelectronic receiving device (14) which receives the light beam reflected from a retroreflector element (18) attached to a patient, and generates a corresponding signal. A display and/or alarm device (24) is connected to the receiving device in order to generate a display and/or alarm signal. <IMAGE>
