Characterisation of a hand-held CZT-based gamma camera for 177Lu imaging

摘要

Small gamma cameras are currently being developed for imaging of small, superficial structures, with applications for sentinel lymph node detection, scintimammography, and parathyroid imaging [ – ]. The larger field of view (FOV) of conventional general-purpose Anger cameras has been sacrificed in favour of a compact camera head that can be positioned more freely, close to the tissue of interest. Positioning is often done manually, sometimes with the assistance of a gantry, and the short source-collimator distance offers a better spatial resolution than what is achievable by a conventional gamma camera. These specialised camera systems are typically optimised for Tc applications. In order to obtain a compact camera head with improved spatial resolution, the detector technologies often differ from the conventional Anger design [ – ].
