Abstract
For phase inversion-based ultrasound imaging with a transmit and receive circuit at an array, a unipolar transmitter is used to reduce the number of high voltage wires. Rather than adding a T/R switch or increasing connections by connecting the receive amplifier to a different electrode than the transmitter, two different receive paths from the element to the receive amplifier are provided. One path is used where the unipolar transmitter ends in one state (e.g., 0V), and the other path is used where the unipolar transmitter ends in another state (e.g., Vtx).
