17. A method comprising:
accessing a current structural estimate of a region of interest;
generating a first simulated X-ray measurement based on the current structural estimate of the region of interest;
receiving a first real X-ray measurement; and
generating an update to the current structural estimate of the region of interest as a function of the first simulated X-ray measurement and the first real X-ray measurement, the update being generated invariant on the current structural estimate.
