In dual‐source dual‐energy CT, the images reconstructed from the low‐ and high‐energy scans (typically at 80 and 140 kV, respectively) can be mixed together to provide a single set of non‐material‐specific images for the purpose of routine diagnostic interpretation. Different from the material‐specific information that may be obtained from the dual‐energy scan data, the mixed images are created with the purpose of providing the interpreting physician a single set of images that have an appearance similar to that in single‐energy images acquired at the same total radiation dose. In this work, the authors used a phantom study to evaluate the image quality of linearly mixed images in comparison to single‐energy CT images, assuming the same total radiation dose and taking into account the effect of patient size and the dose partitioning between the low‐and high‐energy scans. The authors first developed a method …
