Nuclear imaging: a new dimension

BE Oppenheim, PB Hoffer and A Gottschalk

Tomographic techniques used in radiology have also found an application in nuclear medicine. Longtitudinal tomography blurs but does not eliminate structures outside the plane of interest. Transverse tomography eliminates out-of-plane structures, making accurate imaging possible. Positron imaging devices are well suited for transverse tomography because of their high spatial resolution and depth- independent response, but devices using a scintillation camera can visualize large volumes and are not restricted to the use of positron emitters.
