ABSTRACT:
An X-ray equipment comprising an X-ray source and an imaging means detecting the X-rays passed through a subject for digital processing, whereby the imaging means may consist of an X-ray converter film and a sensor or of a storage film and a scanner. Such an X-ray equipment for the digital evaluation of X-rays can be used for panoramic images of a patient's jaw, for thorax images and images of other parts of the body. According to an embodiment of the present invention where an X-ray converter film and a sensor are used, the X-rays are incident on the X-ray converter film 13, which converts same into visible light. The light is passed to sensor 14 by an optical lens unit 18, said sensor being controlled and read by the signal processing unit 15a. The signal processing unit 15a separates, filters and intensifies the image signals and passes them on to the image storage card 16. The image storage card 16 is connected to PC 17, on the monitor of which the X-ray image can be shown and in which PC 17 said image may be permanently filed.
