      Abstract: Cardiac resynchronization therapy (CRT) is a revolutionary treatment for heart failure diseases. Ultrasound echocardiography remains a valuable imaging technique for CRT patient selection, but it is still not accepted by the clinical society because of its inconsistent measurement results. A computational simulation could be a viable approach for validation. This paper reports our initial results of Ultrasound imaging simulation on heart. Based the simulated data and real Ultrasound images, we investigated the methods to improve the speckle tracking and strain estimation in Ultrasound echocardiography. The results turned out that a proper noise filtering and background removal could significantly improve the outputs of speckle tracking and strain estimation
