method and device for matching pixels intensitu00e4tshistogramm executed for imaging system

摘要

A method and an apparatus are described for optimizing operating parameters in an ultrasound imaging system in response to the occurrence of predetermined changes in the pixel intensity histogram of successive image frames. In the method, changes in the pixel intensity histogram of successive image frames are monitored and when the detected changes indicate probe movement, re-optimization of the operating parameters is automatically triggered. In the course of re-optimization, mapping, compression, scaling or beam-forming parameters can be adjusted based on pixel intensity histogram characteristics determined by the system computer. IMAGE
