Rigid Motion Correction for Positron Emission Tomography Brain Imaging KU Leuven
During a positron emission tomography (PET) scan the subject is required to be completely stationary for the duration of the scan. Any motion of the subject will translate into motion blur in the final reconstructed image and may reduce the diagnostic value of the image. Motion during a PET scan can be classified into two main categories: non-rigid and rigid motion. Non-rigid motion deforms the subject and is primarily caused by motion in the ...
