Abstract: Utilization of panoramic X-ray device is getting wider. Panoramic
X-ray has low resolution than general X-ray device and it occurs to distortion
by deviation of image synthesis. Due to structural problems, it has been used
restrictively to identify of tooth structure, not for whole head. Therefore, it
designed and produced panoramic X-ray device which is possible to diagnostic
coverage can be extended and had to be adjusted interval control between X-ray
generator and image processing for whole of Maxillofacia's diagnosis. Produced
panoramic X-ray device is composed basically of short image synthesis. In
addition, it was confirmed the results by used the device which was applied
deviation of the brightness of the image, filter to improve the location of the
deviation and interpolation method. In this study, it was used 13 images including the front. It occurs
to brightness deviation, position deviation, and geometric correction when
synthesis of image, but it had been solved by deviation improvement software
and a change of CCD camera's scan line which is used for image acquisition.
Therefore, it confirmed expansion possibility of utilization range to commonly
used panoramic X-ray device.
