摘要： A guide wire having pressure sensing capabilities for measuring the pressure of liquid in a vessel comprising a flexible elongate member and having proximal and distal extremities and having an outside diameter of 0.018null or less. The distal extremity of said flexible elongate member is adapted to be disposed in the liquid in said vessel. A housing is carried by the flexible elongate member and has a diameter substantially the same as the diameter of the flexible elongate member. The housing has a space therein with a pressure sensor mounted in the space in the housing. The pressure sensor has a diaphragm that is sensitive to changes of pressure in the liquid in the vessel. The diaphragm is rectangular in shape and is bordered by a rim surrounding the well. A backing plate is formed of an insulating material bonded to the crystal and serves to reinforce the rim of the crystal of semiconductor material. The backing plate has a cavity therein underlying the diaphragm and is in substantial registration with the diaphragm. The cavity serves to provide a pressure reference.

摘要： An ultrasound transducer array (408) includes at least one transducer element (412) having a first (604) and second (606) portions separated by an acoustical discontinuity (520). The first portion (604) has the desired length to form a half-wave k31 resonance, while the second portion (606) has a resonant length for an undesired very low frequency out-of-band k31 resonance. The thickness of the transducer element (412) is designed for k33 half-resonance. Given the design, the transducer element (412) can operate and provide for both forward-looking (514) and side looking (512) elevation apertures. A method is also disclosed for using the disclosed ultrasound transducer (412) in ultrasound imaging.
摘要翻译：超声换能器阵列（408）包括至少一个换能器元件（412），该换能器元件具有由声学不连续性（520）隔开的第一（604）和第二（606）部分。第一部分（604）具有期望的长度以形成半波k31谐振，而第二部分（606）具有用于不期望的非常低频带外k31谐振的谐振长度。换能器元件（412）的厚度被设计用于k33半共振。考虑到设计，换能器元件（412）可以操作并提供前视（514）和侧视（512）仰角孔。还公开了在超声成像中使用所公开的超声换能器（412）的方法。
