Practical implementation of real-time low-dose x-ray imaging

实时X射线荧光透视成像的作用正在扩大，并且对于诊断、评价和图像引导介入应用非常重要。2010年，据估计，在北美有超过300万例使用X射线透视进行的心导管插入术。这种频率的主要原因之一是基于导管的治疗的流行率增加。血管成形术，特别是增加支架的球囊膨胀，通过降低再狭窄率显著提高了手术的成功率，允许对以前仅用冠状动脉旁路手术治疗的复杂病变进行微创治疗。心脏介入手术相当长，并且需要对患者进行多次X射线曝光。因此，来自单个介入荧光透视检查程序的辐射剂量可以

The role of real-time x-ray fluoroscopic imaging is expanding and important for diagnostic, evaluation and image guided interventional applications. In 2010, it is estimated that there were over 3 million cardiac catheterization procedures performed in North America using x-ray fluoroscopy. One of the main reasons for this frequency is the increased prevalence of catheter based therapies. Angioplasty, particularly balloon inflation with the addition of a stent, has markedly improved the success of the procedure by reducing the rate of re-stenosis, allowing for a less invasive treatment of complex lesions that were previously exclusively treated with coronary bypass surgery. Cardiac intervention procedures are quite long and require multiple x-ray exposures to a patient. As a result, the radiation dose from a single interventional fluoroscopic procedure can
