ULTRASOUND PROBE AND METHOD FOR MANUFACTURING THE SAME

摘要: An ultrasound probe includes: an acoustic matching layer having a sheet-shaped member whose both ends are bonded together by adhesive to define cylindrical shape and configured adjust impedance of ultrasound; piezoelectric elements arranged along circumferential direction on inner periphery the emit in response input signal convert from outside into echo signal; disc-shaped structural provided one end side longitudinal orthogonal direction, part outer surface being fixed inside layer. The has water repellent portion such that faces, radial gap between
