Abstract
A transmit/receive system for an imaging device includes a transmit circuit configured to generate and output test pulses to a transducer of a probe to cause the probe to propagate an ultrasonic wave through an object. A receive circuit is configured to receive, from the transducer, a composite signal that includes the test pulses output by the transmit circuit and a reflected signal corresponding to reflected waves sensed by the transducer in response to the ultrasonic wave propagated through the object and filter the test pulses from the composite signal and output the reflected signal in accordance with a predetermined minimum frequency of the reflected signal.
