Apparatus and method of determining optimal energy window for optimal positron emission tomography

A method of determining an optimal energy window in positron emission tomography (PET), the method comprising:

• correcting, by a data corrector, data measured from an image quality phantom, wherein the measured data comprises a single gamma photon;
• measuring, by an image quality measurer, an image quality for the corrected data;
• and
• determining, by an optimal energy window determiner, the optimal energy window based on the measured image quality,
• wherein the correcting of the measured data comprises correcting the measured data based on a difference between a first sensitivity of a first radiopharmaceutical and a second sensitivity of a second radiopharmaceutical in at least one energy window.
