Abstract
A data-driven method and system using optical tracking of natural facial features for quick and accurate pose determination during scanning using one or more cameras installed within or on a PET-CT gantry. No patient preparation, fixtures, or artificial features are needed. The pose data is analyzed and incorporated iteratively in reconstruction for reconstruction to motion correct the PET data. The present invention thus results in improved correction of blurring and artifacts caused by head motion during the PET scan.
