X- PORTABLE BITE PART FOR CORRECTING A MOTION OF AN OBJECT IN PANORAMIC COMPUTED TOPOGRAPHY OR CEPHALOMETRIC X-RAY IMAGING

摘要

The present application relates to a portable bite part (230) for correcting a motion of an object (201) in panoramic, computed topography, or cephalometric X-ray imaging. The bite part (230) includes a first end part (233) and a second end part (234). The bite part has known dimensions. The first end part (233) is configured to be disposed in a mouth (202) of an object (201). The bite part further includes markers (231, 232). The markers may recognize positions of the markers (231, 232) from at least two images (237, 238) and calculate a motion of the object (201) for an X-ray imaging unit (100) using the positions of the markers (231, 232) and the known dimensions of a bite stick.
