Probe for electronic scanning type ultrasonic diagnostic apparatus |
摘要 |
A probe for an electronic scanning type ultrasonic diagnostic apparatus in which a plurality of real transducers and one or more pseudo-transducers are arranged in a row on a supporting plate. In order to equalize the ultrasonic directivity characteristics of each of the real transducers, the pseudo-transducers are arranged adjacent to the real transducers which are located at the ends of the row, and have approximately the same shape and dimensions as the real transducers.
