      Published 2019
      Optical motion tracking systems are effective tools for measuring head motion during MRI and PET scans in order to correct for motion. Most systems rely on the attachment of fiducial markers which can slip or become decoupled ...

    • An optimized feature detector for markerless motion tracking in motion-compensated neuroimaging 

      Henry, David; Yao, Yidi; Fulton, Roger R.; Kyme, Andre
      Published 2017
      Head movements during PET and MRI scans can have a detrimental effect on image quality and quantitative measurements. For both modalities, motion correction methods exist that rely on accurate characterization of head ...
