Deep learning results from 1 representative testing subject (55 years of age, female). From top to bottom: UTE echo 1 and echo 2 images, reference CT, segmented reference CT of the skull, DL synthetic CT of the skull, and the absolute difference between the 2. For this subject, the Dice coefficient for skull masks between DL synthetic CT and the reference CT is 0.92, and the mean absolute difference is 96.27 HU.
