A regression model of ultrasound reflectivity from normal myocardium.
In this paper the potentialities of back-scattered ultrasound to detect changes in transmural myocardial wall structure have been assessed by using a second order regression model of integrated back-scatter. The model was tested through simulation studies and experimental measurements. The experimental results prove the proposed model attractive to detect physiological transmural changes in myofibre orientation from epicardial to endocardial left ventricular wall.
