We compare the performance of low tube voltage with hybrid iterative reconstruction (iDose) standard and filtered backprojection (FBP) using phantoms at computed tomographic coronary angiography. In angiography, application combined iDose resulted in significant image quality improvements compared to FBP. Image was same or better despite a reduction radiation dose by 76%
