An analogue device that is temporarily placed in a patient's mouth to perform routine diagnostic dental imaging procedures. It uses analogue-to-digital conversion techniques to record the absorption pattern of x-ray beams used in the diagnosis and treatment of diseases of the jaw or oral cavity structures. The device is used in combination with the x-ray source (x-ray tube) that is located outside the patient's mouth during the imaging procedure; the resulting digital image is transmitted to a monitor or workstation.
