Title: (DE) DIAGNOSEGERÄT
(EN) DIAGNOSTIC APPARATUS
(FR) APPAREIL DE DIAGNOSTIC
Abstract:
(EN) A diagnostic apparatus comprises a source (1) of probing electromagnetic radiation and means (2) for transmitting the output from the probing radiation source (1) to biological tissue (3) to be examined. The apparatus also comprises means (4, 41) for detecting probing radiation reflected from the tissue (3) and stimulated radiation resulting from excitation of the tissue (3) by the probing radiation. A processing means (5-9) responsive to the reflected and stimulated radiations to produce a signal for diagnosis of the condition of the tissue and means (15, 16) for regulating the intensity of the probing radiation including a feedback circuit (16, 17, 18) for controlling the regulating means (15) and responsive to the intensity of the probing, reflected and/or stimulated radiation are also included.
(FR) Un appareil de diagnostic comporte une source (1) de rayonnement électromagnétique d'exploration et des moyens (2) pour transmettre le signal de sortie depuis la source de rayonnement d'exploration (1) jusqu'au tissu biologique (3) à examiner. Cet appareil comprend également des moyens (4, 41) permettant de détecter le rayonnement d'exploration réfléchi par le tissu (3) et le rayonnement stimulé résultant de l'excitation du tissu (3) par le rayonnement d'exploration. L'appareil possède d'autre part un organe de traitement (5-9) réagissant aux rayonnements réfléchi et stimulé en vue de produire un signal permettant le diagnostic de l'état du tissu, ainsi que des moyens (15, 16) pour réguler l'intensité du rayonnement d'exploration, comportant un circuit de rétroaction (16, 17, 18) commandant le moyen de régulation (15) et réagissant à l'intensité du rayonnement d'exploration, réfléchi et/ou stimulé.
