1. A computer-implemented method of compressing CT reconstruction images, comprising:
receiving a volumetric density file comprising one or more voxels, each comprising a voxel density value;
replacing a first set of voxel density values below an air density value with the air density value;
replacing a second set of voxel density values above a material density value with the material density value;
determining a set of the one or more voxels as voxels of interest;
replacing a third set of non-interesting voxel density values below a material surface density with the air density value;
replacing a fourth set of non-interesting voxel density values above the material surface density with the material density value;
quantizing all voxels of the one or more voxels to provide a reduced volume image; and
compressing the reduced volume image to provide a compressed volume image.
