Abstract:
Methods, systems and computer program products for nondestructive ultrasound imaging are provided. An example method defines a plurality of subarrays, each comprising a plurality of ultrasound transducer elements. The method transmits a plurality of ultrasound beams from each of the plurality of subarrays, each ultrasound beam being transmitted at a preset beamsteering angle. Subsequent to each transmit, the method receives, at the array, a plurality of ultrasound reflections corresponding to the plurality of ultrasound beams. For each point to be imaged, the method selects one set of received element data for each of the plurality of subarrays. The selected set of element data corresponds to an ultrasound beam having a focal point closest to the point to be imaged. Finally, the method reconstructs a point to be imaged based on the selected received element data, and constructs an ultrasound image by repeating this process for each point to be imaged.
