ABSTRACT:
A low cost x-ray imaging system for dental radiography employs an intra-oral imaging device comprising a head portion insertable into a patient's mouth and a body portion forming a handle and containing a conventional solid state camera. The head portion employs low cost, commercially available components, including a flourescent film for converting x-ray images into visible light, and a prism or reflecting mirror for redirecting the visible image onto an image pickup such as a CCD array in the camera. The device outputs conventional RS-170 video signals which are processed by a conventional PC computer cooperating with a controller to control the timing and dosage of the x-rays received by the patient.
