According to the University of Sydney’s Dr. Roger Fulton, a promising method of correcting for patient head motion during helical CT imaging has been developed.
The method reconstructs a motion-corrected image from an orbit that is modified based on knowledge of the head motion during the scan, which is obtained by optical motion tracking or a data-driven algorithm.
Results from real CT scans of moving phantoms, and simulations of a variety of realistic volunteer head motion patterns were shown to illustrate the ability of the method to compensate effectively for all but the most severe types of motion patients might exhibit in the clinical setting.
