METHOD FOR DETERMINING GEOMETRICAL PARAMETERS AND / OR STATE OF MATERIAL OF THE OBJECT UNDERSTANDED BY RADIOGRAPHY

摘要

The invention relates to a method for determining, by radiography, the geometrical parameters of the object under study, which can be described geometrically. The length of the path of radiation passing through the material of the object under study can be determined by the projection of the object, for example a tube, the image of which is formed by an x-ray or gamma radiation source subject to the availability of data on the exposure of the radiographic image. At the same time, the sections of trajectories passing through the material of the object and curves calculated on the basis of them assume that the size of the object under study, for example, a pipe, may be larger than the size of the receiver (film / detector) used to obtain the radiographic image. When implementing this method, the radiation source, the object under study and the receiver (film / detector), which serves to obtain a radiographic image, are in fixed positions.
