The Radialis PET Imager (or Radialis PET Camera) is a high spatial resolution, small field-of-view PET imaging camera specifically developed for close-range, organ-targeted (i.e., limited field) imaging. The Radialis PET Camera is a partial-ring planar PET camera, equipped with lutetium-containing gamma-ray detectors, which collect gamma rays emitted by injected positron-emitting radiopharmaceuticals, and generates images corresponding to the relative concentrations of these radiopharmaceuticals in the body. The Radialis PET Camera is designed to collect gamma rays emitted by the injected radiopharmaceutical in a patient’s body part with high efficiency.
An assembly of devices comprising a diagnostic, positron emission tomography (PET) imaging system used to detect, record, quantify and analyse 511 kilo-electronvolt (keV) photon emission patterns resulting from annihilation reactions produced during the decay of positron emitting radiopharmaceuticals. It produces three-dimensional (3-D) tomographic digital cross-sectional physiological images representing distribution patterns of positron emitting radiopharmaceuticals ingested by, or injected into the patient. It typically uses lead collimators and specialized software for image reconstruction allowing mapping of metabolic patterns and rates associated with targeted physiological processes.
