Abstract
A method and an apparatus for panoramic dental X-raying comprises an arm ( ) rotating about an axis ( ), a radiation source ( ) at one end ( ) of the arm for generating an X-ray beam ( ), a shutter ( ) for shaping the X-ray beam, and at the opposite end ( ) of the arm, a recorder ( ) for receiving the X-ray beam after it has passed through the dental arch for forming an image of the dental arch. The X-raying is performed with rotation of the arm ( ) so as to image substantially the entire length of the dental arch. The shutter ( ) narrows the X-ray beam ( ) in the front area of the dental arch in order to increase the thickness of the sharply imaged layer compared to the two sides of the dental arch.
