确诊冠心病后心肌梗塞等缺血性心脏病需靠冠伏动脉造影。而导管直接插入冠状动脉有很大的危险性,且需住院及特殊的血管造影设备,检查费用也高。Rubenstein等1981年开始用同步辐射经静脉注“射造影剂进行冠状动脉造影,能清晰地显示冠状动脉的影像,目前正在积极地研究其实用化问题。电子被加速后发生电磁波,特别是电子在加速器或斯脱耳化圆筒中以近似光的速度旋转,会产生宽频带连续能量光谱的高强度、定向性良好的电磁波,这就
Diagnosis of coronary heart disease after myocardial infarction and other ischemic heart disease should rely on coronary artery angiography. Catheter directly into the coronary artery has a great risk, and require hospitalization and special angiography equipment, inspection costs are high. Rubenstein et al. (1981) began the coronary angiography with synchrotron radiation via intravenous injection of contrast agent to clearly show the images of coronary arteries and is now actively studying its practical application. Electrons are accelerated after they are accelerated, especially in the Rotating the accelerator or spurring cylinder at approximately the speed of light produces a high intensity, highly directional electromagnetic wave in a broadband continuous energy spectrum
