摘要: A γ-ray scanner (10) includes a Solid-State Single-Photon Detector (12) and γ- ray radioisotope source (11) certified as safe for domestic use such Americium oxide (Am-241) that requires no certification since its low intensity is over extended periods of exposure to human body. The may be used monitoring fixed object (51, 71, 84) an imaging assembly (52) having in one embodiment stationary annular gantry (82) surrounding the armature fixedly supports γ-source detector mutual opposed alignment external object, so they are constrained move together. rides around inside periphery gantry, while or moves laterally direction parallel rotation axis beam along object.
