Figure 7: Ultrasound imaging – three methods to extract motion information from 4 chamber view acquisitions. 1) Fixed sample: reads motion information from myocardial velocity imaging. A user-defined region of interest (ROI) is kept static throughout the heart cycle to maintain the analysis and the interaction as simple and reproducible as possible. 2) Manual tracking: reads motion information from myocardial velocity imaging. It requires the user to define a ROI on the myocardium at end-systole and end-diastole. This ROI is interpolated in space to mimic the myocardial movement. 3) Speckle tracking: uses block matching techniques to follow speckles from B-mode images and estimate the myocardial motion.
