Ultrasonic probe

摘要

An ultrasonic probe that can be relatively easily manufactured and has a desired ultrasonic radiation surface. The ultrasonic probe includes: plural supporting materials, each having a principal surface on which plural signal wires are formed, the plural supporting materials arranged such that the principal surfaces are oriented in different directions from one another; plural groups of ultrasonic transducers, plural ultrasonic transducers in each group having plural electrodes formed on side surfaces, the plural electrodes respectively joined to the plural signal wires formed on the principal surface of the respective one of the plural supporting materials.

1. An ultrasonic probe comprising:
plural ultrasonic transducer arrays, each including (i) a supporting material having a principal surface on which plural signal transmission paths are arranged, and (ii) plural ultrasonic transducers attached to the principal surface of said supporting material and one-dimensionally arranged in an elevation direction, each of said plural ultrasonic transducers having an ultrasonic radiation surface and a side surface on which two electrodes are arranged, and said side surface being attached to the principal surface of said supporting material such that said two electrodes are joined via electrically conductive pastes to selected two of the plural signal transmission paths arranged on the principal surface of said supporting material; and at least one holding member having a surface curved in an azimuth direction and formed with grooves each oriented in the elevation direction, the supporting materials of said plural ultrasonic transducer arrays being inserted into the grooves, and said at least one holding member being configured to hold said supporting materials such that said plural ultrasonic transducer arrays are radially arranged in the azimuth direction.
