Computed Tomography

Computed Tomography. Radiography: 3 problems 3D collapsed to 2D Low soft-tissue contrast Not quantitative. X-Ray CT solves these problems (but costs much more $$). The mathematics behind X-Ray CT (reconstruction from projections) applies to other modalities as well (PET, Spect, etc).
