DEVICE FOR DIAGNOSTICS AND THERAPY OF BIOLOGICAL OBJECTS Russian patent published in 1999 - IPC

FIELD: medical engineering, namely optical devices. SUBSTANCE: radiation from laser radiator passes to biological object through light guide. Size of light beam dispersed by biological object into photometric head is set by means of adjustable diaphragm. Light dispersed by biological object passes through diaphragm. It is dispersed by plate, reflected from internal wall of head and gets to photoreceiver through selective multifrequency light filter. After passing through the latter radiation dispersed by biological object is decomposed into spectral components each of which is recorded by photoreceiver. Electric signals from photoreceiver output pass to recording unit which is responsible for digital conversion and mathematical processing of input signals. Device allows true and objective determination of pathology stages with reduced time of treatment result evaluation. EFFECT: enhanced accuracy of diagnostics. 1 dwg
