ABSTRACT:
Digital radiography apparatus uses a resonance-type high frequency inverter having a main switch in series with an auxiliary switch. An X-ray tube receives the pulsed power from the high frequency inverter, after voltage ampliflication and rectification, emitting pulsed X-rays to a patient. A TV camera obtains X-ray transmission images of the patient, and an image processor generates a visual diagnostic image by subtracting one X-ray transmission image from another. The high frequency inverter circuit is controlled synchronously with the processing operation of the image processor.
