Abstract

Construction of realistic models of the muscle fibers in myocardium is relevant for simulating the electro-mechanical behavior of the heart. Advances in microscopy imaging have improved the potential for visualization of the 3D distribution of myocytes. In this paper, we propose an approach to identify cardiac fibers structures, in multi-photon confocal microscopy images. Our method is based on contrast invariant features such as the multi-scale local phase image, to obtain a tensor representation of the local structure. We show here some results obtained from multi-photon microscopy images acquired in a fetal rabbit heart, where the cardiac microstructure can be extracted from the image in terms of fiber direction as well as fiber compactness. Experiments from phantom data also show a successful application of the proposed methodology.
