<p>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 selfscanning 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.</p> |
