Prior Image Guided Undersampled Dual Energy Reconstruction with Piecewise Polynomial Function Constraint
Dual energy CT has the ability to give more information about the test object by reconstructing the attenuation factors under different energies. These images under different energies share identical structures but different attenuation factors. By referring to the fully sampled low-energy image, we...
