Figure 1From: Video image-based analysis of single human induced pluripotent stem cell derived cardiomyocyte beating dynamics using digital image correlation Beating analysis framework. A: The cell is divided into 8 sectors, each being of 45°, with the center point being at the observed beating focus point of the cell. The sectors are numbered in a clockwise manner. B: The radial and tangential components of the velocity vectors in each sector are calculated with regard to the sector centerline going through the beating focus point.Back to article page
