Abstract
The present invention relates to an ultrasound imaging system in which the scan head either includes a beamformer circuit that performs far field subarray beamforming or includes a sparse array selecting circuit that actuates selected elements. When used with second stage beamforming system, three dimensional ultrasound images can be generated.
Claims12
A medical ultrasound imaging system comprising:
- a two dimensional array of transducer elements in a probe housing;
- a beamformer device in a second housing, the beamformer being in communication with the probe housing, the beamformer device receiving first beam image data from a first subarray and having a first plurality of second beam image delay lines that receive first beam image data and receiving data from a second subarray with a second plurality of delay lines that receive second beam image data, the first subarray and the second subarray operating in parallel to provide three dimensional image data.
