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.
