Abstract
Provided is a technique for evaluating properties of a membranous tissue or a surface of the tissue in a biological body by ultrasonic waves. A method of the invention includes setting one or more measurement points on a surface of the biological tissue to be inspected; measuring, in a state in which an elastic wave propagates to the biological tissue, at least a surface wave of the elastic wave by measuring a displacement of the biological tissue at the measurement point by using an ultrasonic wave; and calculating an index value indicating physical properties of the biological tissue by using the measured displacement.
