摘要： A capacitive ultrasound transducer capable of operation in collapsed mode either with a reduced bias voltage, or with no bias voltage, is provided. The transducer includes a substrate that is contoured so that a middle region of the flexible membrane is collapsed against the substrate in the absence of a bias voltage. A non-collapsible gap may exists between the substrate and peripheral regions of the flexible membrane. The contour of the substrate may be such as to strain the flexible membrane past the point of collapse, or to mechanically interfere with the flexible membrane. The substrate may include a further membrane disposed beneath the flexible membrane, the further membrane being contoured so that the flexible membrane is collapsed against it. The substrate may a support disposed beneath the further membrane to deflect a corresponding portion of the further membrane upward toward the flexible membrane. The support may be a post. The transducer may be operated in collapse mode with an improved efficiency (k2eff) as compared to otherwise similar conventional transducers exhibiting comparably uncontoured substrates. A related medical imaging system is provided, which may include an array of such transducers disposed on a common substrate. A method of operating such a transducer is provided that includes operating the transducer in the collapse mode in the absence of a bias voltage.

摘要： An array of cMUT cells are formed on individually isolated massive plates on a substrate. The mass of each plate provides an inertial force in opposition to the force and motion of transmission by the cell which reduces the resultant translation of motion in the plate. The reduction in motion results in less coupling of acoustic energy into the substrate and contamination of the signals of adjacent cMUT cells by lateral waves. The unwanted wave coupling into the substrate can be further damped by compliant or sparse periodic mounting of the massive plates on the substrate.
摘要翻译： cMUT电池阵列形成在基板上的单独隔离的块状板上。每个板的质量提供与电池的传递力和力的相反的惯性力，这降低了板中运动的最终平移。运动的减少导致声能较少耦合到衬底中并且通过侧向波污染相邻cMUT单元的信号。可以通过在基板上的块状板的顺从或稀疏周期性安装来进一步阻尼到衬底中的不需要的波耦合。

摘要： An ultrasonic diagnostic imaging system for shear wave measurement transmits push pulses into tissue for the generation of shear waves. Characteristics of the shear waves such as their velocity of passage through the tissue are measured to assess properties such as tissue stiffness. The measurements are compensated for effects of background motion by sampling echo signals from the tissue at different times and comparing the samples to detect the presence of relative motion between the ultrasound probe and the region of interest where shear waves are detected. Sensed background motion is used to adjust measured shear wave characteristics.
