Quantitative comparison of 68-keV monoenergetic, routine-dose, and low-dose 120-kVp CT for calcium-mimicking inserts in thoracic phantoms: effects of phantom size and reconstruction method
68-keV monoenergetic images from dual-energy CT are often compared with conventional 120-kVp CT, but quantitative performance may depend on phantom size, reconstruction method, and dose settings. We performed a technical phantom-based comparison of 68-keV monoenergetic, routine-dose, and low-dose 120-kVp CT for calcium...
