  • Publication number: 20240164746
    Abstract: An ultrasonic diagnostic system includes an ultrasonic diagnostic device having a probe, a moving device configured to move the probe, and a control device. When ultrasonic diagnosis is performed on a subject, the control device controls the moving device such that the probe is pressed against a body surface of the subject, and in a case where a specific pattern is designated as a movement pattern of the probe, controls the moving device such that the pressing of the probe on the body surface is canceled or alleviated, then controls the moving device such that the probe is moved with the specific pattern, and when the movement with the specific pattern is ended, performs a specific control for controlling the moving device such that the probe is pressed against the body surface.

  • Publication number: 20230057999
    Abstract: A catheter includes a transmission unit that is disposed at the distal end of a tube having a lumen and has an ultrasonic wave transmitting function; a reception unit that is disposed at the distal end of the tube and has an ultrasonic wave receiving function; and an acoustic lens that is disposed so as to cover only the transmission unit among the transmission unit and the reception unit. Ultrasonic beams transmitted from the transmission unit are converged by passing through the acoustic lens, and a reflected wave reflected on biological tissue is received by the reception unit without passing through the acoustic lens. Since setting of the positions, number, and the like of the reception units is not bound by the position, size, and the like of the acoustic lens, the positions, number, and the like of the reception units can be appropriately set to improve ultrasonic reception efficiency.

  • Publication number: 20230056415
    Abstract: A catheter having a lumen includes a tube, a sensor unit disposed at a distal end of the tube and capable of transmitting and receiving ultrasound, and an irradiation unit disposed at the distal end of the tube and capable of emitting the ultrasound toward a guide wire which passes through the lumen and protrudes from the distal end of the tube. The shape of the biological tissue can be observed by transmitting the ultrasound from the sensor units toward the biological tissue and receiving the reflection wave reflected by the biological tissue at the sensor units. Irradiating the guide wire with the ultrasound transmitted from the irradiation unit causes the guide wire to vibrate. The vibration of the guide wire can facilitate the passage through an occlusion site of the biological tissue.
