A submatrix spatial coherence approach to minimum variance beamforming combined with sign coherence factor for coherent plane wave compounding
BACKGROUND:The coherent plane wave compounding (CPWC) is a promising technique to enhance the imaging quality while maintaining the high frame rate in the plane wave ultrasound imaging. Recently, the spatial-coherence-based ...
Adaptive scaling Wiener postfilter using generalized coherence factor for coherent plane-wave compounding
AbstractThis paper proposes an adaptive scaling Wiener postfilter (AScW) for coherent plane-wave compounding (CPWC) to improve the image quality. AScW introduces an adaptive scale factor dependent on the signal incoherence to maintain the ...
Highlights- An adaptive scaling Wiener postfilter (AScW) is proposed for CPWC image quality improvement.
Dynamic coherence factor based on the standard deviation for coherent plane-wave compounding
AbstractThe ultrafast imaging technique based on plane wave transmission has been a commonly investigated imaging mode in medical ultrasound imaging. Coherent plane-wave compounding (CPWC) was proposed to improve the quality of plane-wave ...
Highlights- Dynamic coherence factor (DCF) is proposed to adaptively determine the number of plane waves based on the angular difference of CPWC.
