title: [A novel myocardial motion estimation algorithm for ultrasonic image using optimal window size].
abstract: OBJECTIVE
  To establish a novel speckle tracking algorithm for estimating myocardial motion.
  
  
  METHODS
  A search method was proposed to find the optimal window size for image matching. Simulation and clinical experiment were conducted to demonstrate the validity of this algorithm.
  
  
  RESULTS
  The optimal window size for image matching was determined using this algorithm. Correct speckle tracking could be fulfilled with the algorithm proposed.
  
  
  CONCLUSIONS
  The method proposed in this paper is effective for speckle tracking.
