APPARATUS AND METHODS FOR DETERMINING SPATIAL COORDINATES OF USING RADIO LABELLED TISSUE

摘要

A system (20) and method for diagnostic testing of structures within a body, e.g., organs within the body of a living being, which has been provided with a radioactive imaging agent, e.g., a radiotracer, to cause the structure to produce gamma rays, associated characteristics X-rays, and a continuum of Compton-scattered photons. The system (20) includes a radiation receiving device, e.g., a hand-held probe (22) or camera, an associated signal processor (30B), and an analyzer (30I-30R). The radiation receiving device is arranged to be located adjacent the body and the structure for receiving gamma rays and characteristic X-rays emitted from the structure and for providing a processed electrical signal representative thereof. The processed electrical signal includes a first portion representing the characteristics X-rays received and a second portion representing the gamma rays received.
