  • APPARATUS AND METHOD OF DETERMINING OPTIMAL ENERGY WINDOW FOR OPTIMAL POSITRON EMISSION TOMOGRAPHY
    Publication number: 20150185338
    Abstract: An apparatus and method for determining an optimal energy window for optimal positron emission tomography (PET) is disclosed. An optimal energy window determining apparatus may include a data corrector configured to correct data measured from an image quality phantom, an image quality measurer configured to measure an image quality for the corrected data, and an optimal energy window determiner configured to determine the optimal energy window based on the measured image quality. The data corrector may correct the measured data based on a difference between sensitivities measured using different radiopharmaceuticals in at least one energy window.
    Type: Application
