Methods, systems and apparatuses for Van-Cittert Zernike imaging
Abstract:
A method of creating an ultrasound image includes receiving a return signal from a time delayed signal emitted from a plurality of transducer elements at a target the return signal comprising a measurement at each of the plurality of transducer elements formed from a plurality of reflections off of a plurality of volume elements forming a two dimensional slice of a target, computing a Van-Cittert Zernike (VCZ) curve for each of the plurality of volume elements based upon the measured return signals and creating an short-lag spatial coherence (SLSC) image comprising a plurality of pixels each associated with one of the plurality of volume elements wherein each of the plurality of pixels comprises a value computed from a metric of the VCZ curve computed for each of the associated plurality of volume elements.
