摘要
The present invention relates to a method to determine geometrical parameters of an object under study by means radiography, the object can be described geometrically, wherein intercepts that go through the material of the object under study can be determined from a projection of the object - e.g. a tube - imaged by an X- or gamma-radiation source if exposition data of the radiographic image are available. These intercepts that go through the material of the object - i.e. the intercept curves - allow that the object under study - e.g. the tube - have a dimension that is larger than the dimension of the device (film/detector) used to take the radiographic image. During the course of said method, the source of radiation, the object under study and the device (film/detector) used to take the radiographic image are in a fixed position.
