1. A system, comprising:
a processor configured to:
receive an uncorrected image and acquisition geometry metadata;
determine an acquisition classification based at least in part on the acquisition geometry metadata;
based at least in part on the acquisition classification, determine whether a correction factor corresponding to the acquisition classification exists;
in response to determining that the correction factor corresponding to the acquisition classification does not exist:
determine the correction factor; and
store the correction factor; and
associate the uncorrected image with the correction factor; and
a memory coupled to the processor and configured to provide the processor with is instructions.
