在这项研究中，入射表面剂量率接收的体模在电影血管造影和荧光透视进行了比较。测量中使用的X射线条件是进行经皮冠状动脉介入治疗的设施中通常使用的条件。尽管目前用于心脏介入放射学（IVR）的X射线设备的入射表面剂量（电影血管造影和荧光透视）趋于低于以前，但某些设备会产生高辐射剂量。因此，用于心脏IVR程序的X射线设备必须保持良好的维修状态，并且必须仔细校准。此外，需要定期测量用于心脏IVR的电影血管造影和荧光透视的X射线设备的辐射剂量。如使用中的X光系统辐射剂量过高，应找出原因，并设法减低辐射剂量。因此，必须接受足够的辐射防护训练。
In this study, the entrance surface dose rates received by a phantom during cineangiography and fluoroscopy were compared. The X-ray conditions used in the measurements were those normally used in facilities performing percutaneous coronary intervention. Although, today, the entrance surface doses (cineangiography and fluoroscopy) of X-ray equipment used for cardiac interventional radiology (IVR) tends to be lower than they were previously, some equipment produces a high radiation dose. Therefore, the X-ray equipment used for cardiac IVR procedures must be maintained in good repair and must be carefully calibrated. In addition, periodic measurement of the radiation dose from the X-ray equipment used for both cineangiography and fluoroscopy for cardiac IVR is necessary. If the radiation dose of the X-ray system in use is too high, the IVR staff should determine the reason and make an effort to reduce it. Hence, the IVR staff must be adequately trained in radiation protection.
