Determination of the surface of the heart is a challenging problem due to the heart's motion and the potential importance of subtle geometric features. The Meyer watershed has been shown to be an effective solution to this problem in images of the left ventricle in at least two medical image types. In this paper the technique is extended, first of all, by application to the right ventricle (RV) in an image from the Dynamic Spatial Reconstructor (DSR). Additionally, several important issues related to its general application are addressed including: (1)image anisotropy, (2)4D processing and (3) valve localization. The Meyer watershed model itself is also discussed in some detail with respect to its implementation and general properties. A simple by-product of surface reconstruction of the RV in the DSR images is that of the pulmonary arteries.
