The increasing use of cineangiography to determine the volume of the left ventricle of the heart is of considerable interest in the assessment of cardiac performance both in normal and diseased states (Arvidsson and Karnell, 1964; Soloff, 1966; Bristow, Van Zee and Judkins, 1970). In addition, the effect of therapeutic intervention may be evaluated (Rees et al., 1971). However, radiographic images produced by non-parallel X-rays are magnified and distorted, and may cause gross error in volume calculations (Arvidsson, 1961; Dodge et al., 1966).
