Shifted Helical Computed Tomography to Optimize Cardiac Positron Emission Tomography–Computed Tomography Coregistration: Quantitative Improvement and Limitations

Molecular Imaging, 2010
Positron emission tomography–computed tomography (PET-CT) uses CT attenuation correction but suffers from misregistration artifacts. However, the quantitative accuracy of helical versus cine CT in the same patient after optimized coregistration by ...
