摘　　要：目的 :研究右冠状动脉在轴位X线造影上的正常形态、行径、和分布规律。方法 :9例新鲜心脏标本的右冠状动脉注入造影铸型剂后 ,对其进行多方位多角度投照 ,并与相应方位铸型标本对比分析。结果 :正位时 ,右冠状动脉分支清楚 ;左前斜位时 ,随着角度增大 ,右冠状动脉主干逐渐伸展 ;右前斜位 40°以内时 ,分支显示清楚 ,但随着角度增大 ,右冠状动脉主干重叠明显 ;当影像增强器由头倾位向足倾位旋转时 ,右冠状动脉主干逐渐伸展。结论 :左前斜位 40°～ 6 0°、正位 +头倾 2 0°适合观察右冠状动脉主干近段 ;左侧位适合观察右冠状动脉主干中段 ;右前斜位 2 0°～ 40°、正位适合观察右冠状动脉的主要分支 ;左前斜位 30° +足倾 2 0°适合观察右冠状动脉主干全段。Objective: To investigate the axial X ray angiographical image, course and distribution of right coronary artery(RCA).Methods: After injected with the A.B.S.,the RCAs of 9 fresh heart specimens were photographed on different view.Those images were compared with the cast specimen of heart.Results: From posterior anterior view, the branches of RCA were seen clearly; form left anterior oblique view, the main part of RCA had a extending trend with the enlargement of angle; from right anterior oblique view, RCA had a marked foreshortening trend.When the image intensifier was rotated from cranial to caudal, the main part of RCA was observed to have a extending trend.Conclusion: The proximal part of RCA can be observed properly from left anterior oblique view with an angle of 40°～60°, or in posterior anterior view with a cranial angle of 20°; the middle part of RCA can be observed properly from left lateral view; the branches of RCA can be observed properly from right anterior oblique view with an angle of 20°～40° or from posterior anterior view.The total main part of RCA can be observed properly from left anteror view with a oblique angle of 30° and a caudal incline of 20°.
