Gur, D; Sashin, D; Sternglass, E J

Apparatus for exposing an object to x-ray radiation including adjustable object supporting and compressing means and first collimator means having an opening and being disposed between the x-ray generator and the object supporting means. Second collimator means having an opening and being disposed between the object supporting means and x-ray detecting means. Means are provided for moving the first and second collimator means in such fashion as to maintain alignment between the openings therein and the x-ray generator, in order to sequentially expose portions of the object of x-ray passing through the first collimator means and permit such x-ray to pass through the opening in a second collimator means and impinge upon the x-ray detecting means. The object supporting and compressing means is preferably structurally independent of the collimator means. The x-ray detecting means preferably takes the form of a highly sensitive detector such as a film-screen cassette or a selfscanning array of photodiodes optically coupled to scintillator means.
