用于冠状动脉电影造影术的常规安装的X射线系统限制X射线束与患者的横向平面的角度，并且电动支架的使用将旋转限制为60°至70°。可用投影的这些局限性严重妨碍了冠状动脉的充分检查。采用西门子Cardoskop-U型冠状动脉造影机，对100例连续患者的冠状动脉进行了标准斜位投照、头侧和尾侧成角斜位投照和110°斜位投照。这些动脉造影由两名专家观察员独立检查。在大约20%的患者中，额外的视图揭示了否则会被遗漏的病变。在另外34%的患者中，诊断得到了显著改善，因为病变的全部范围被显示出来，避免了分支重叠或偏心性狭窄的程度得到了提升。在12例标准投影动脉造影明显正常的患者中，有4例患者的病变被额外的视图所掩盖。
Conventionally mounted X-ray systems for coronary cinearteriography limit angulation of the X-ray beam to the transverse plane of the patient, and use of the motorized cradle restricts rotation to 60° to 70°. These limitations of available projections seriously hamper adequate examination of the coronary arteries. With use of the Siemen's Cardoskop-U, which was designed to overcome this problem, the coronary arteries of 100 consecutive patients were examined with standard oblique projections, and in addition with cranial and caudal angulated oblique and 110° oblique projections. These arteriograms were independently examined by two expert observers. In approximately 20 percent of patients the additional views unmasked lesions that would otherwise have been missed. In a further 34 percent the diagnosis was significantly improved because the full extent of a lesion was revealed, overlap of branches was avoided or the degree of an eccentric stenosis was upgraded. In 4 of 12 patients with apparently normal arteriograms in standard projections, lesions were unmasked by the additional views.
