    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: 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.
