3D imaging of radioactivity in man measured with a whole body counter

In the Medical Physics Department of the University of Insubria, Varese, Italy, a whole body counter is in use, for clinical and radioprotection measurements. It consists of a scanning bed, four opposite (anterior-posterior and laterallateral) NaI(Tl) detectors and a shielding based on the shadow-shield principle. By moving the bed on which the patient lies in the supine position, the longitudinal profiles of the counts measured by each probe...
