Claim 17:
18. A method for locating a detection element (DT) of an X-ray detection system as claimed in claim 6, the method comprising the following steps:
rotating the support of the collimation device about its axis of rotation (Δ) at a fixed angular speed of rotation (V);
exposing the assembly formed by the support and the second support to an X-ray beam from the X-ray source during the rotation of the support;, detecting electrical pulses produced when, on any one of the windows passing between the emitter and the receiver of the optical fork, the receiver receives the light wave;
the detection element (DT) detecting X-rays passing through the slit in the support for a first angular position (alpha) of the second support and a second angular position (beta) of the second support,
the processing unit determining the projected position (C) in the main plane of the support based on the first and second angular positions,, the first and second angular positions being obtained on the basis of the indexes of the two windows that have produced the electrical pulses which are temporally closest to the two successive times for which the detection by the detection element (DT) has taken place.
