摘要： A capacitive micromachined ultrasound transducer (cMUT) comprises a lower electrode. Furthermore, the cMUT includes a diaphragm disposed adjacent to the lower electrode such that a gap having a first gap width is formed between the diaphragm and the lower electrode. Additionally, the cMUT includes at least one element formed in the gap, where the at least one element is arranged to provide a second gap width between the diaphragm and the lower electrode.

摘要： An ultrasonic transducer probe having a highly integrated interface circuit array. Low-voltage transmit control signals from the system are transmitted on the system transmit channels via the ultrasound probe cable and into the interface circuit array. These transmit control signals are routed through the interface circuit array using a dense switching matrix. Once the low-voltage transmit control signals reach individual cells within the interface array, they are decoded and used to control local high-voltage pulser circuits to drive individual ultrasound transducer elements made up of selected subelements that are co-integrated with the interface electronics. The interface cell circuitry further comprises a high-voltage transmit/receive switch, which is closed when the high-voltage pulser is transmitting to protect the low-voltage components.
摘要翻译：具有高度集成的接口电路阵列的超声换能器探针。来自系统的低电压发射控制信号通过超声探头电缆在系统发射通道上传输到接口电路阵列中。这些发送控制信号使用密集的交换矩阵通过接口电路阵列路由。一旦低压发射控制信号到达接口阵列内的单个小区，就将它们解码并用于控制本地高压脉冲发生器电路，以驱动由与接口电子器件共同集成的选定子元件组成的各个超声换能器元件。接口单元电路还包括高压发射/接收开关，当高压脉冲发生器正在传输时，该高压发射/接收开关闭合以保护低电压部件。
