A receiver array has a plurality of receiver elements on a substrate to detect in-phase and quadrature components of a received signal corresponding to a transmit signal. Each of the receiver elements includes a receiver transducer and a thin-film transistor (TFT) receiver circuit. The TFT receiver circuit includes a quadrature detector having a mixer to mix a received signal with a reference signal in a composite bias signal that is distributed across the plurality of receiver elements. A transmitter is acoustically coupled to the plurality of receiver elements to generate the transmit signal through an imaging medium."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultrasonic imaging using thin film transistor backplane","description":"An embodiment is a method and apparatus for coherent ultrasonic imaging.
