Movement artifacts during whole body scanning are a major concern when reproducible results are required. The sway of the body was determined by a force plate. The resulting standard deviation is less than the resolution of the scanner.
Movement artifacts within the body, like head rotation, are hard to control.
Again, the pointer on the head assists in reducing the artifacts. The ventilation depth during the scan determines the shape of the chest and should be standardized to get reproducible results. Inc. All rights reserved.
