Capacitive ultrasonic probe device |
摘要 |
Within the tip portion of a cylindrical shaped sheath a capacitive ultrasonic transducer which is an array type two-dimensionally arrayed on the outer surface of the cylindrical face is disposed. Capacitive ultrasonic transducer units employ m capacitive ultrasonic transducer elements arrayed in the longitudinal direction of the cylindrical face as a division unit, thereby providing an arrangement wherein the respective capacitive ultrasonic transducer units are readily disposed in the circumferential direction, whereby radial scanning or the like can be performed within a body cavity.
