ABSTRACT:
A dielectric sheet one side of which is coated with a film of thermoplastic material is heated to the softening point of thermoplastic material prior to exposure to object-modulated X-rays in an ionography imaging chamber whose interelectrode gap is filled with a high Z gas. The thus obtained relief image on the film is cooled prior to transferring the sheet into a second gas-filled gap of the imaging chamber wherein the sheet is in register with the light source and optical elements of a device which renders the relief image visible in accordance with the schlieren optical effect. The relief image can be projected onto a web of photosensitive material to produce a permanent record of the relief image. During movement back into the interelectrode gap, the sheet is caused to pass along a corona discharge device which neutralizes its charge, and the sheet is heated to the softening point of the thermoplastic material to erase the preceding relief image and to render the sheet ready for exposure to X-rays which are modulated by another object.
