  • Patent number: 4346983
    Abstract: An x-ray imaging system for intraoral dental radiography. The imaging process is based on xeroradiographic principles, the surface of a small photoconductive plate being electrically charged. After insertion into a carrier, to form a light-tight cassette, the photoconductive plate is placed in a patient's mouth and x-ray exposed. The cassette, and the resultant electrostatic charge image therein, is inserted into the system processor, the photoconductive plate removed and transported to a developer station wherein the image is developed using liquid toner. The toner image is then dried and transferred from the photoconductive plate by using a transparent adhesive material and fixed to a white plastic substrate, forming an image carrier wherein the image can be viewed in reflectance or transmittance. After cleaning, the photoconductive plate is available for reuse. The system has a storage compartment for receiving cleaned photoconductive plates of various sizes for subsequent insertion into an empty cassette.
