ULTRASONIC PROBE AND ULTRASONIC IMAGING APPARATUS

摘要

An ultrasonic probe and ultrasonic imaging apparatus, wherein the artifacts from transverse waves generated at the substrate of a capacitive micro-machined ultrasonic transducer are reduced. The substrate thickness of the ultrasonic transducer is set to a suitable range so that the energy of the transverse waves within the sensitive band (91) of the ultrasonic transducer is efficiently emitted to the outside, thereby reducing artifacts in ultrasonic imaging.
