Optimization of contrast sensitivity and specificity of quadratic ultrasonic imaging

Abstract

We present a new algorithm of post-beamforming second order Volterra filter (SOVF) for deriving the quadratic kernel based on the convolution of the singular modes quadratic kernels which give the highest contrast-to-tissue ratio (CTRs) to extract quadratic components from ultrasound contrast agent (UCA) nonlinear echoes with single transmission. The new… (More)
