Abstract
Systems and methods are provided for performing operations including: 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.
Claims30
A system comprising:
- a memory;
- and
- one or more processors that, when executing instructions stored in the memory, are configured to perform operations 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.
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.
A non-transitory computer-readable medium comprising non-transitory computer-readable instructions that, when executed by one or more processors, configure the one or more processors to perform operations 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.
