ABSTRACT:
Method and apparatus for the production of tomographic images includes a flying spot scanner to form, from a beam of penetrating radiation, a pencil beam sweeping over a line in space to define a sweep plane. An object to be examined is supported so that the pencil beam intersects the object along a path passing through the object and a selected slice of the object. A line collimator is provided for filtering radiation scattered by the object, the line collimator has a field of view which intersects the sweep plane in a bounded line so that the line collimator passes only that radiation scattered by elementary volumes of the object lying along the bounded line. A radiation detector responds to that portion of the scattered radiation which is passed by the line collimator.
