Abstract
A collimator for an X-ray testing machine and a method for adjusting the collimator with the aid of a detection system disposed in the collimator that includes at least two spatially separate detection devices, disposed and spacing one behind the other.
Claims13
An X-ray testing machine comprising:
- an X-ray source for generating X-ray radiation;
- elements for generating a primary beam of the x-ray radiation;
- a collimator for the x-ray radiation;
- means for orienting the collimator relative to the primary beam including a central, blind-bore opening in said collimator;
- and
- first and second detection devices disposed and spaced one behind the other inside the central opening.
3 more elements
A method for adjusting a collimator in an X-ray testing machine relative to a primary X-ray beam comprising:
- providing first and second X-ray detection devices, which are spatially separated, disposed and spaced one behind the other along the primary beam;
- and, using the signal from the first and second detection devices to spatially orient the collimator so that the primary beam impacts the centers of the first and second detection devices at a right angle by:
- in a first step, moving the collimator until a signal at the first detection device is maximal;
- and
- in a second step, rotating the collimator in two independent planes about a point in a first rotational plane until a signal from the second detection device is maximal.
