difference between radiography and computed tomography - correct answers radiography reduces 3D patient anatomy to 2D projection image and has superimposition of anatomy; computed tomography has a thin slice/2D image which corresponds to a 3D section of the patient without superimposed anatomy isotropic - correct answers x = y = z in voxel size reason why isotropic voxels are desired - correct answers allows you to create high resolution coronal and sagittal reconstructions; makes it easie...
