The 3-dimensional reconstructions in the following pages have been created from MR images of gelled perfusion fixed hearts from the Visible Heart® library using Mimics (Materialise, Leuven, Belgium), see Static Imaging Methodologies for more information on this process. The myocardial tissue was segmented out from the raw DICOM images and constructed into 3D models of the specimens. In some cases the adipose tissue was segmented away from the myocardial tissue to provide more information to the user. The videos you see in these pages were created in two ways:
- Positioning the models in the attitudinally correct orientation, with respect to the anterior posterior reference plane, and subsequently rotating the model around the superior inferior axis.
- Cutting the model in half to represent an echocardiographic 5 chamber view and subsequently rotating the two halves.
The specimens of the Visible Heart® library have been categorized into hypertrophic, dilated cardiomyopathy (DCM) and healthy specimens by assessing the medical histories and the anatomical structure of each specimen. From a purely anatomical perspective the heart of a DCM patient is typically associated with large ventricular volumes and relatively low wall thicknesses and the heart of a hypertrophic patient usually exhibits smaller ventricular volumes and large wall thicknesses.
