Abstract
A PASS ultrasonic system includes a separate receive channel for each respective element in an ultrasonic transducer array which imparts a delay to the echo signal produced by each respective element. The delayed echo signals are summed to form a steered, dynamically focused and dynamically windowed receive beam which can be readily interpreted even when the transmit beam does not emanate from the center of the array.
