摘要： An Ultrasonic Equipment and its Catheter-type Ultrasonic Probe can be inserted in capillaries such as blood vessels, and comprises a catheter-type ultrasonic probe for generating ultrasonic waves by a piezoelectric transducer arrayed at its tip. A plurality of the piezoelectric transducer segments are arrayed on a two-dimensional plane, perpendicular or approximately perpendicular to the insertion direction of the probe into a capillary with their ultrasonic wave emitting surface faced in the insertion direction. A part of the plane is cut out to provide a guide unit for passing a treating catheter or a guide wire in the insertion direction.

摘要： An ultrasonic angioscope system which uses an imaging technique of sending ultrasonic waves to a portion ahead of a stricture of a blood vessel and visualizing a portion in the forward direction of the angioscope, and which uses a laser breakdown is provided. The ultrasonic angioscope system includes: a laser generating device (11) installed outside the human body; a probe (20) that introduces laser beams (13) emitted from the laser generating device (11) into a blood vessel (1) via an optical fiber (12), is set at the tip of the optical fiber (12), and has a lens (14) and a water tank (15) as a dielectric; ultrasonic-wave generating means that uses a laser breakdown (16) produced in the water tank (15); a plurality of hydrophones (18) that receive reflected waves, of ultrasonic waves emitted by the laser breakdown (16), from a stricture portion (2) of a blood vessel (1), and are disposed at the tip end of the probe (20); and means of forming a stricture-shaped image of the stricture portion (2) based on the signals received from the hydrophones (18) by a synthetic aperture method.
