我们比较了低管电压与混合迭代重建（iDose）、标准低管电压与滤波反向投影（FBP）在CT冠状动脉造影（CTCA）中的性能。在CTCA，与低管电压与FBP相比，低管电压与iDose的联合应用显著改善了图像质量。尽管与标准管电压相比，FBP的辐射剂量降低了76%，但图像质量相同或更好。
We compare the performance of low-tube voltage with the hybrid iterative reconstruction (iDose) with standard- and low-tube voltage with the filtered backprojection (FBP) using phantoms at CT coronary angiography (CTCA). At CTCA, application of the combined low-tube voltage with iDose resulted in significant image quality improvements compared to the low-tube voltage with FBP. Image quality was the same or better despite a reduction in the radiation dose by 76% compared with standard-tube voltage with FBP.
