title: A new geometric description of the right ventricle.
abstract: An accurate model of the geometry of the right ventricle would be particularly useful for volume determination by imaging techniques, as well as for mechanical modelling. In this study, a new mathematical model for the right ventricle geometry based on its crescentic cross-sectional shape is proposed and used to calculate its volume in imaged ex-vivo casts. An excellent correlation (r = 0.97) was found between volume as derived from the model and actual volume measured by water displacement.
