APPARATUS FOR DETECTING, LOCALIZING, AND IMAGING OF RADIATION IN BIOLOGICAL SYSTEMS Collimating probes (10, 20, 100, 200, 300, 400, and 500) and probes (720 and 1100) and associated collimators (800, 900 and 1000) for detecting, localizing, and mapping or imaging radiation emanating from a hidden source, such as within the body of a living being. One continuously adjustable collimating probe (10) comprises a radiation detector (26) and an adjustment mechanism (30) for continuously adjusting the solid angle which radiation may pass to the detector. A receptacle (600) is also provided to hold a specimen on that probe. Non-adjustable probes (720 and 1100) adapted to be used with separate, readily securable, collimators (800, 900 and 1000) are also provided. When any such collimator is used on the probe it enables the adjustment of the probe's solid angle of acceptance in at least one discrete increment.
