VM Image Construction

(A) Polyenergetic 140-kVp image; (B) and (C) benchmark VM images from DECT using 80- and 140-kVp projection data, reconstructed at 80 and 110 keV, respectively; (D) and (E) the corresponding VM images produced at the same energies using our DL approach from only 140-kVp images; (F) the horizontal profiles through the abdominal aorta in the 140-kVp, 80-keV DECT VM, and 80-keV DL VM images; (G) the data of (F) zoomed to the central region, including the aorta. All images are displayed with a window width of 200 HU centered at 50 HU. In these images, some representative structures are compared, including the adipose tissue (green arrows), contrast-enhanced muscle and kidneys (blue arrows), contrast-enhanced blood in the abdominal aorta (pink arrow), calcified plaques (yellow arrowheads), and bone (yellow arrows).
