Ultrasonic Eye Examination System for Early Detection and Classification of Cataract in Real Time

摘要

The early detection, classification and estimation of non-invasive real-time cataract hardness includes: an ophthalmological probe (102) to send and receive acoustic eye signals; A liquid-filled delay line (101) to improve eye-to-eye transmission and time discrimination between emission and echos; A RESULTS DISPLAY SYSTEM WITH A WIRELESS (108) OR WIRELESS INTERFACE (109). THE DEVICE UNDERSTANDS: A SIGNAL RECEIVER FOR EXCEPTING THE PROBE AND DETECTION AND AMPLIFICATION OF ECOS (103); A HIGH SPEED ANALOG-DIGITAL CONVERSION BOARD FOR ACQUIRING AND SCANNING ECOS (104); A DIGITAL SIGNAL PROCESSING UNIT (105) FOR: SIGNAL CONDITIONING; EXTRACTION OF TEMPORAL AND SPECIAL CHARACTERISTICS; DETECTION OF INCIPIENT CATARACT; SEVERITY GRADE CLASSIFICATION; CATARATE HARDNESS ESTIMATION AND WITH SELF-LEARNING AND CALIBRATION CAPACITY.
