- Description:
- Estimation of shift between signals of two ultrasound images is the key of sonoelastography. Comparison of three methods - cross-correlation function and two versions of SAD (sum of absolute differences) has been conducted for various displacements and estimation parameters using a soft tissuemimicking gelatin phantom with harder inclusion. Resulting displacement maps were evaluated by comparison of average values and their standard deviations. and Obsahuje seznam literatury
