ABSTRACT:
An ultrasonic imaging apparatus and method combines dynamically focused reception and coded transmission/reception technologies by inexpensive circuitry. A receive aperture is divided into smaller apertures. Correspondingly, a receive beam former is divided into receive sub-beam formers36ato36nby which a phase alignment and summing process is performed. Thereafter, coded signals are compressed in decoders37ato37nin a time axis direction. Output signals from the decoders are once again subjected to a phase alignment and summing process in a second beam former.
