<p>For the purpose of providing a cross-talk correction method for easily removing leakage of fluorescent light occurring between scintillators adjacent in a slice direction, first function fitting means (51) in a channel direction and second function fitting means (53) in a slice direction determine an ideal projection length, In(D n ), from slope phantom projection information (41), Equation (1) is then used to determine leakage coefficients µ + and µ_, and subsequently, cross-talk removing means (82) determines intensity information D n from detected information S n making up subject projection information (42) on a subject using Equation (2) and the leakage coefficients µ + and µ_; thus, the leakage component for scintillators adjacent in the slice direction contained in the subject projection information (42) is removed by a simple method to eliminate artifacts due to leakage in the slice direction, hence improving image quality.</p> |
