Ultrasonic probe and ultrasonic diagnostic apparatus using the probe |
摘要 |
An ultrasonic probe including a plurality of transducer elements for transmitting an ultrasonic wave and receiving a reflected ultrasonic wave from inside of an object to be examined, electrodes for applying a voltage to the transducer elements, and an acoustic matching layer for taking a matching of an acoustic impedance between the transducer elements and the object to be examined, wherein the acoustic matching layer includes a plurality of materials each of which has a different acoustic impedance and has an anisotropy in acoustic characteristic between an ultrasonic wave-transmitting direction from the transducer elements and a direction perpendicular to the ultrasonic wave-transmitting direction.
