ABSTRACT Radiography apparatus including a source of radiation, a collimator positioned between the radiation source and an object to be exposed, scintillator apparatus for receiving the radiation passing through the object and converting it into light and a self-scanning, integrated array of photodiodes for receiving light produced by the radiation and emitting responsive electrical signals. Fiber optic coupling is provided between the scintillator means and the self- scanning photodiode array. The self-scanning array of photodiodes is planar and has at least two parallel rows of linear self-scanning photodiode arrays. The linear arrays of one row are staggered with respect to the linear arrays of a second row. In another embodiment, two collimators each being cylindrical and generally hollow are provided, the self-scanning arrays need not be two linear rows and the optical coupler need not be a fiber optic device.
