This research aims to quantify the errors introduced by patient motion during PET scans and their impact on scatter correction.
Simulations were performed on attenuation maps to assess motion effects.
Comparison of scatter simulation results for tracers [11C]Verapamil and [18F]FDG using different μ-map reconstruction techniques.
Automated Image Registration (AIR) was applied for motion correction and alignment of PET images.
Characterization of motion-induced errors showed significant over-corrections in scatter for high uptake regions.
TXTV μ-map reconstruction improved scatter simulation outcomes compared to traditional methods.
AIR removed artifacts and restored quantification in dynamic scans, aligning images to a common reference space.
