[Single plane Simpson's method for measurement of right ventricular volume by X-ray ventriculography].

Objective: To study the validity of single plane Simpson's method with conventional X-ray ventriculography for estimation of right ventricular (RV) volume.

Methods: Fifteen human RV casts were obtained from 15 subjects who died from non-cardiac causes within 24 hours after death. These casts were photographed respectively and their volumes were calculated by using the single plane Simpson's method based on a new half-circle model.
