Abstract
A radiological scanning apparatus for forming an image of an object on a film by scanning said object with a flat fan shaped beam. The film is conformed so as to form a surface of revolution. The surface of revolution is, on the one hand, moved in the same movement as the scanning movement of said beam, and on the other hand it is rotated about its axis of revolution so as to renew a surface exposed to said beam in order to reduce the dimension of said film considered in the direction of said scanning movement.
