Abstract
A medical examination installation for generating images of a patient for visual display has a mechanical oscillator which vibrates at least a portion of the patient, of which an image is to be obtained, during the exposure time. The image is obtained with a pick-up device at an image frequency, and the mechanical vibration may be matched to, or differ from, the image frequency. The image is then subjected to image subtraction techniques, or selective filtering, which permits body parts which differ in terms of mechanical vibration properties from the surrounding tissue, for example calculi, to be clearly imaged, particularly the borders of those body parts.
