ABSTRACT:
A digital radiographic imaging system which employs co-operative means for converting the x-rays to an optical image having enhanced quality and detecting said optical image. The x-ray conversion medium employed in the improved radiographic system is positioned physically contiguous to a bi-directional array of electrical charge transfer devices which convert the optical image to an electronic analog representation thereof. Digital information processing means are further included in the improved radiographic system to convert the electronic analog representation of the optical image to a recorded digital representation thereof. The x-ray conversion medium being employed in the improved radiographic system is a high efficiency scintillator body which moves co-operatively with the photo detection means being employed in a further synchronious relationship with a moving fan beam of X radiation being employed to generate the desired optical image after passage through a stationary object.
