1. A system comprising:
a storage device storing a plurality of reference sub-volumes, each of the plurality of reference sub-volumes associated with a respective vertebra; and
a processing unit to execute processor-executable program code to cause the system to:
determine an image volume;
identify a plurality of sub-volumes of the image volume, each of the plurality of sub-volumes of the image volume associated with a respective one of a plurality of vertebra;
for each of the plurality of sub-volumes of the image volume:
determine a coordinate system of a reference sub-volume associated with a same respective vertebra as the sub-volume, the determined coordinate system of a first reference sub-volume being different from the determined coordinate system of a second reference sub-volume;
determine a transform from a coordinate system of the sub-volume of the image volume to the determined coordinate system of the reference sub-volume associated with a same respective vertebra as the sub-volume of the image volume, the determined transform to a coordinate system of a first reference sub-volume being different from the determined transform to a coordinate system of a second reference sub-volume; and
apply the transform to the sub-volume to register the sub-volume to the reference sub-volume associated with a same respective vertebra;
input the registered sub-volumes and the image volume to a trained neural network;
receive an output image volume from the trained neural network, the output image volume labeled to associate voxels with respective vertebra; and
display the output image volume.
