Abstract
An improved method is proposed for the image information of a body by ultrasonic scanning in which the resolution of the image can be greatly improved without sacrifice in the penetrability of the ultrasonic waves, i.e. without increasing the ultrasonic frequency, into the body under inspection. The improvement comprises: PA0 attaching a central ultrasonic absorber to the ultrasonic objective lens of the ultrasonic probe; and PA0 inserting an auxiliary concave lens between the ultrasonic probe and the body under inspection.
