Statistics of the log‐compressed echo envelope

摘要: Log compression of A lines to produce B‐scan images in clinical ultrasound imaging systems is a standard procedure control the dynamic range images. The statistics such compressed terms underlying scatterer have not been derived. are analyzed for partially formed speckle using general K distribution model envelope derive density function log‐compressed envelope. This used elucidate relation between moments envelope, parameters, and scatterers. analysis shows that mean an increasing both backscattered energy effective density. variance decreasing independent energy.
