Multi-laser beam-scanning through living body penetration diagnosis and treatment apparatus

Abstract

In a diagnosis apparatus, a laser beam is radiated toward a living body, and this laser beam effects plane scanning in longitudinal and transverse directions of the living body, and the laser beam passed through the living body is received by a light-receiving detection plate. The laser beam radiation scanning device and the light-receiving detection plate are supported for rotation as a set, so that penetration images can be obtained in various directions without the need for moving the living body. If two sets of devices, each including the above laser beam radiation scanning device and the above light-receiving detection plate, are angularly spaced 90.degree. from each other about the living body axis, a penetration data viewed from the front side of the living body, as well as penetration data viewed from the lateral side, can be obtained. Therefore, by processing these data by a computer, a colon endoscope or a catheter inserted into the living body can be graphically displayed as a stereoscopic penetration image on a television monitor. Further the two sets of the devices are located in various angular positions to obtain penetration images viewed in various directions so that an image of a focus obtained by contrast medium can be displayed on a television monitor by computer graphics. Further, using these devices, a diagnosis is made by a laser fluorescent penetration image of the living body or a fluorescent spectrophotometric pattern image, a laser treatment program and a spectrophotometric pattern recognition, thus effecting the diagnosis and the treatment simultaneously.
