Abstract
Official abstract text for this publication.
Normalization coefficients in are computed for positron emission tomography (PET) continuous bed motion acquisition (CBM). The normalization coefficients for the lines-of-response in CBM account for the change in decay of the injected isotope over time and/or changes in velocity of the bed motion.
First claim
Opening claim text (preview).
We claim: 1. A method for computing normalization coefficients in continuous bed motion acquisition, the method comprising: acquiring, with a positron emission tomography (PET) scanner having a plurality of rings of detectors, line-of-response events from radioactive decay of an isotope in a patient while the patient is moving on a bed at different velocities in the PET scanner; calculating normalization coefficients for the line-of-response events, the normalization coefficient…
