TRANSDUCER ARRAY, AND ACOUSTIC WAVE MEASUREMENT APPARATUS INCLUDING TRANSDUCER ARRAY

摘要

PROBLEM TO BE SOLVED: To solve such a problem that, when a plurality of transducers each having a rectangular receiving surface on a recessed support part having a quadric surface of revolution, if the transducers are disposed with their vertices of outer edges of the receiving surfaces brought close to each other, a spacial frequency of a transducer arrangement space is reduced, and resolution power of an acoustic wave image is limited.SOLUTION: The transducer array includes: a support part, the inner surface of which is defined by a quadric surface of revolution formed according to an imaginary quadratic curve rotating about an imaginary rotation axis and having a plurality of openings; and a plurality of transducers each of which includes a receiving surface having a substantially parallelogram shape so as to be fitted in the opening. The receiving surface is arranged in the transducer array such that any one of the four vertices is closer to the imaginary rotation axis than the other three vertices.SELECTED DRAWING: Figure 1
