Abstract
A first set of ultrasound data values is obtained that correspond to the position of a biological tissue at a first time. A second set of ultrasound data values is obtained corresponding to positions of the biological tissue at a second time. A feature pattern is located in the first set of ultrasound data values so as to provide a reference feature pattern. A search region is determined in the second set of ultrasound data values that corresponds to the located reference feature pattern in the first set of ultrasound data values. A feature pattern is located in the search region of the second set of ultrasound data values so as to provide a candidate feature pattern corresponding to the reference feature pattern. A correlation is determined between the reference feature pattern in the first set of ultrasound data values and the candidate feature pattern in the search region in the second set of ultrasound data values. A candidate feature pattern is selected in the search region in the second set of ultrasound data values based on the correlation. The movement of the biological tissue is determined based on the reference feature pattern and the selected candidate feature pattern.
