18. A method comprising:
accessing, by one or more hardware processors, a current structural estimate of a region of interest; and
using a trained machine learning model based on the current structural estimate of the region of interest to generate a first simulated X-ray measurement, the first simulated X-ray measurement being used with a first real X-ray measurement to generate an update for a structural estimate, the update generated invariant on the current structural estimate.
