Modeling the Anatomy of the Human Heart
Using the Cryosection Images of the Visible Female Dataset
Abstract
Anatomical models of the human heart
describe the distribution of tissue including the orientation of fibers
and sheets. These models are the foundation for the simulation of the electrophysiological
and mechanical cardiac behavior. These simulations help to improve diagnostic
and surgical techniques as well as the medical education. In this work
the cryosection images of the Visible Female dataset and a variety of digital
image processing techniques were applied to achieve a realistic, highly
detailed anatomical model of the heart. The model is stored in a three
dimensional data set consisting of approximately 80 million cubic voxels.
Each voxel has a size of 0.33 mm x 0.33 mm x 0.33 mm and was assigned to
one out of 20 different tissue classes. The incorporation of the myocardial
fiber and sheet orientation makes the model of interest for applications
in the scope of numerical field calculation. The model can be applied eg
in the area of elasto- and fluidmechanics as well as electrophysiology
of the human heart.
