Ultrasonic probe with thermal transfer means |
摘要 |
<p>The present invention relates to an ultrasonic probe provided with a piezoelectric element for ultrasonic generation that has drive electrodes formed on two main surfaces thereof; an acoustic matching layer formed on the first main surface side of the piezoelectric element; a backing member attached to the second main surface side of the piezoelectric element; a base for heat dissipation provided on a lower surface of the backing member; and a thin metal plate for heat transfer that is thermally bonded between at least one of the main surfaces of the piezoelectric element and the base for heat dissipation; wherein the thin metal plate for heat transfer is surface-bonded to extend from one end of the piezoelectric element over the center thereof toward the other end. This configuration ensures that heat generated by the electrical-mechanical conversion of the piezoelectric element is transferred away in a satisfactory manner, enabling suppression of any temperature rise in the piezoelectric element.</p> |
