1. A system comprising:
a storage device;
a processor to execute processor-executable process steps stored on the storage device to cause the system to:
determine a plurality of sets of two-dimensional projection images, where each set of two-dimensional projection images includes two-dimensional projection images acquired from a plurality of projection angles;
from each of the plurality of sets of two-dimensional projection images, reconstruct an associated three-dimensional image volume;
from each of the plurality of sets of two-dimensional projection images, determine an associated subset of two-dimensional projection images, wherein a number of projection angles from which a given subset of two-dimensional projection images were acquired is less than a number of projection angles from which a given set of two-dimensional projection images associated with the given subset were acquired; and
train an artificial neural network to generate an output three-dimensional image volume based on input two-dimensional projection images, the training based on the subsets of two-dimensional projection images and the reconstructed three-dimensional image volumes.
