ABSTRACT:
An apparatus for examining an object placed on a support arrangement and located between a source of penetrating radiation and a radiation responsive detector arrangement comprising an image intensifier tube in conjunction with an internal or external continuous detector screen, the combination of said source and said detector arrangement together with adjustable beam collimating means being mounted so as to allow for a rotation relative to the object about an axis extending perpendicularly to a cross-sectional plane of said object, comprising an electronic control arrangement for selectively adjusting the format and/or resolution of a television pattern obtained by scanning the image at the target of a television camera tube and resulting from the projection of the image produced at the output of said detector arrangement, and position selecting means for orientating the position of said support arrangement selectively and in dependence of the adjustment of said electronic control arrangement with respect to the position of said source, detector arrangement and collimating means in such a manner that said body can be irradiated with a substantially conical beam or with a substantially flat diverging beam.
