Probe for electronic scanning type ultrasonic diagnostic apparatus.

摘要

A probe for electronic scanning type ultrasonic diagnostic apparatus has a linear array of similar electro-acoustic transducers (2-1 to 2-N) and one or more pseudo-transducers (7-1, 7-2) arranged in a row. In order to equalize the ultrasonic directivity characteristics of each of the actual transducers, the pseudo-transducers (7-1, 7-2) are arranged adjacent to the end transducers (2-1, 2-N), and have approximately the same shape and dimensions as the actual transducers (2-1 to 2-N).
