THE APPARATUS FOR DIAGNOSING NON-INVASIVE ARTICULAR PATHOLOGY USING JOINT SOUND ANALYSIS AND METHOD THEREFOR

摘要

PURPOSE: An apparatus and a method for diagnosing noninvasive degenerative-joint-disease based on the analysis of joint sound are provided to noninvasively diagnose the degenerative-joint-disease by using the joint sound generated from the friction of cartilage according to the angle change of the joints. CONSTITUTION: A signal collecting part(100) receives a signal for measuring joint sound and a signal for measuring the movement angle of the joints. A joint sound dividing part(200) divides the joint sound generated while the movement of joints. A signal converting part(300) converts the divided joint sound into a signal in a time-frequency region. A noise erasing part(400) erases noises included in the signal in the time-frequency region. A variable extracting part(500) extracts a specific variable from the signal in the time frequency region.
