摘要：
Energy-resolved computed tomography (CT) is a method that can generate multiple CT images reconstructed by the X-rays in specific energy ranges. We have previously discussed a lattice absorber type of X-ray detector for energy-resolved CT. We have now developed a band absorber type detector with the aim of improving spatial resolution. We compare spatial resolution and contrast-to-noise ratios for the two types of detectors.
