Optimizing Radiation Dose Levels in Prospectively Electrocardiogram-Triggered Coronary Computed Tomography Angiography Using Iterative Reconstruction Techniques: A Phantom and Patient Study
Figure 1
Noise reduction in images reconstructed with iDOSE4 in phantom.
At equal radiation doses, iDose4 reconstruction algorithm yielded lower image noise than FBP reconstruction algorithm, and with increased iDose4 level, image noise decreased in a linear manner.
