Comprehensive analysis of 3D collagen fiber orientation in chick embryo heart samples using advanced imaging and modeling techniques. The first row focuses on the right ventricle (RV), showing a 3D rendering of the heart (first column), a high-resolution 2D confocal microscopy image of collagen fibers (second column), a 3D vector field visualization of fiber orientations (third column), and a polar distribution plot illustrating predominant fiber orientation around 90 degrees (fourth column). The second row provides similar analyses for the left ventricle (LV), with corresponding visualizations and orientation data.
