A new geometric description of the right ventricle.
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.
