Title:
DATA CORRECTION FOR NUCLEAR MEDICINE IMAGING WITH SUPPLEMENTAL TRANSMISSION SOURCE
Document Type and Number:
WIPO Patent Application WO/2024/059537
Kind Code:
A3
Abstract:
Systems, methods, and devices provide data correction for positron emission tomography (PET) examinations using an external, supplemental radioactive source. The supplemental radioactive source is formed of a uniformly distributed radionuclide. The uniformly distributed radionuclide is positioned in a support structure which is positioned into an inner bore of a PET scanner and secured in place by a friction fit, or directly integrated into the PET system. A transmission source control system moves the one or more transmission sources into the support structure for performing the PET examination (e.g., using a hydraulic system). The transmission source control system also retracts the one or more transmission sources back into a source storage device upon completing the PET examination. Various data correction algorithms use the first PET signal data, originating from a radiotracer injected in the patient, and second PET signal data, originating from the uniformly distributed radionuclide.
