A METHOD FOR PRODUCING THE RADIOLOGICAL IMAGE OF AN OBJECT, PREFERABLY FOR USE IN MATERIAL TESTING, AND A MEANS FOR ITS PERFORMANCE

摘要

Improved method in the field of transmission-type radiology making it possible to apply this method even in cases where its application has up till now not been possible for disturbing factors, e.g. if determining features at hidden spots or if distortion is caused by media filled inside or surrounding the object to be tested. It facilitates among others the determination of: the wall thckness of pipes; the presence of deposits, encrustations, and the like; the formation of drift media. The otherwise known method is completed according to the invention by inserting into the radiation path - between the test body and the receiver - a modifying body which consists in a laminated thin layer package obtained by packing at least three thin flat sheets upon each other and arranged in a manner that the axis of the radiation path is including an angle of maximum 60o with the normal of the thin layer surface, preferably the said axis and the said normal are lying collaterally with each other. When evaluating the thus obtained radialogical image, the substantial and geometrical features of the modifying body are also taken into consideration.
