Abstract
A nuclear imaging system includes a scanner (), such as a PET scanner. A patient is injected with a [N]ammonia radioisotope tracer which is contaminated with a small percent ofF contamination. The scanner receives radiation from the injected tracer and a reconstruction processor () reconstructs the detected radiation into image representations. A calibration processor () generates an estimated decay curve based on the proton bombardment and a priori information about the tracer. An activity meter () measures radiation emitted from a sample of the tracer and a dose calibrator () determines a decay curve from the measured radiation. The detected radiation is corrected with one of the decay curves during reconstruction or a correction processor () corrects reconstructed images with one or both of the decay curves. A display () displays uncorrected reconstructed images and the decay curve and/or the corrected images.
