Ultrasound sensor element, ultrasound sensor array assembly, ultrasound transmit sensor element, imaging device, ultrasound transducer, and method of performing an ultrasound scan

An ultrasound sensor array assembly comprising a two dimensional array of ultrasound sensor elements, each sensor element in the two dimensional array of ultrasound sensor elements comprising:

• an ultrasound transducer,
• a transmit circuit configured to provide an electrical signal to the transducer for output of an ultrasound signal;
• and
• a receive circuit configured to receive an electrical signal from the transducer, based on a received reflected ultrasound signal,
• wherein the transmit and receive circuits each comprise one or more thin film transistors;
• the sensor array assembly further comprising:
• a plurality of transmit delay circuits, wherein each transmit delay circuit is in electrical communication with each sensor element in a row of the array of sensor elements, and wherein the transmit delay circuits are configured to delay a transmit signal to the sensor elements in each row for steering a beam of emitted ultrasound;
• and
• a plurality of receive delay circuits, wherein each receive delay circuit is in electrical communication with each sensor element in a column of the array of sensor elements, and wherein the receive delay circuits are configured to delay a receive signal from the sensor elements in each column for steering the beam of received reflected ultrasound;
• wherein the plurality of transmit delay circuits are incorporated into a first driver circuit, and the plurality of receive delay circuits are incorporated into a second driver circuit, and the first and second driver circuits are located external and adjacent to the two dimensional array of ultrasound sensor elements.
