越来越多地使用电影血管造影术来确定心脏左心室的容积,这在评估正常和疾病状态下的心脏性能方面具有相当大的意义(Arvidsson和Karnell,1964; Soloff,1966;布里斯托、货车Zee和Judkins,1970)。此外,可以评估治疗干预的效果(Rees等人,1971年)。然而,由非平行X射线产生的射线照相图像被放大和扭曲,并且可能导致体积计算中的严重误差(Arvidsson,1961; Dodge等人,1966年)。
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).
