Claim 0:
1. A computer-implemented method to automatically detect an out-of-view CT scan, comprising:
receiving a voxel density file;
determining a threshold iso-value of density between air density and a material density of one or more scanned objects in the voxel density file; and
evaluating, using the threshold iso-value of density, one or more horizontal slices of the voxel density file to determine whether at least a portion of the one or more scanned objects is out of view,
wherein evaluating comprises determining a lateral out-of-view shift,
wherein determining a lateral out-of-view shift comprises determining a horizontal slice comprising a longest continuous arc of intersection between a view cylinder boundary and voxels above the threshold iso-value of density is above a lateral out-of-view shift threshold.
