Abstract
Abstract A method of image display of a specimen by an ultrasonic wave microscope comprising an acoustic wave propagating medium, a piezoelectric member provided at one end of said medium for generating an ultrasonic beam, and an acoustic wave lens formed at an opposite end of said acoustic wave propagating medium and having a predetermined focal point, said method comprising the steps of two-dimensionally scanning a specimen disposed substantially at said focal point by said ultrasonic beam while moving one of said specimen and said beam relative to the other, and applied to said specimen repetitive stress selectively during the scanning of said specimen.

Claim 3
Dependent Claim
30 words
A method of image display according to claim 1, wherein repetitive stress is applied to said specimen when said specimen is scanned at other than a predetermined scanning range thereof.
Claim 4
Dependent Claim
42 words
A method of image display according to claim 1, wherein said repetitive stress is applied to said specimen when the scanning is carried out for all but one of a predetermined number of image frames in an image display of said specimen.
