ULTRASONIC EYE-CHECK SYSTEM FOR EARLY DEPRESSION AND REAL-TIME CATARACT CLASSIFICATION

摘要

The device for early detection, classification and determination of cataract hardness in real time, in a non-invasive manner, includes: an ophthalmologic probe (102) with the function of sending and receiving acoustic eye signs; A DELAY LINE FILLED WITH A LIQUID (101) TO IMPROVE THE TRANSMISSION OF THE SIGNS TO THE EYE AND TEMPORARY DISCRIMINATION BETWEEN EMISSION AND ECOS; A SYSTEM FOR VIEWING RESULTS WITH A WIRE (108) OR WIRELESS INTERFACE (109). THE DEVICE COMPRISES: A SIGNAL REACTOR FOR EXCITING THE PROBE AND EC DETECTION AND AMPLIFICATION (103); A HIGH-SPEED ANALOG-DIGITAL CONVERSION PLATE FOR ACQUISITION AND SCANNING ECOS (104); A DIGITAL SIGNAL PROCESSING UNIT (105) FOR: SIGNAL CONDITIONING; EXTRACTION OF TEMPORATIVE AND SPECTACULAR CHARACTERISTICS; INCIDENTAL CATARACT DETECTION; CLASSIFICATION OF THE DEGREE OF SEVERITY; ESTIMATION OF CATARACT HARDNESS AND WITH CAPACITY OF SELF-TRAINING AND CALIBRATION.
