A Generalized Correlation-Based Model for Out-of-Plane Motion Estimation in Freehand Ultrasound

A big challenge in sensorless image-based ultrasound tracking is in the out-of-plane motion estimation. The correlation value of a specific model of speckle known as fully developed speckle (FDS) can be used to estimate the out-of-plane displacement. In real tissue, this kind of pattern is rare and...
