A digital X-ray machine and operating control system includes and X-ray source and software operated processor control system. The operator may enter patient characteristics affecting radiological density into a control panel so that a processor determines X-ray signal strength. The X-ray beam is collimated, passes through the patient and the support table and then through an ion chamber. A scintillator device converts the X-rays to light in the 600-650 nm range, and passes the light in a straight line from the X-ray source through a beam attenuator in the form of a spectral filter controlling the light transmission. The light then passes through an optical lens gathering the light and finally into a CCD camera. The CCD is sensitive to light in the 600-650 nm range and converts the light to electrical pulses for producing an X-ray image of the patient. Imaging software optimizes the image of the radiograph to diagnostic quality. The system is intended for small animal veterinary use but may be adapted for human use.
