title: Nuclear imaging: a new dimension.
abstract: 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.
