METHOD OF DETERMINATION OF GEOMETRICAL DISPLACEMENT OF SENSORS IN FLAT PANEL DETECTOR OF X-RAY IMAGE Russian patent published in 2015 - IPC G01N23/04 

FIELD: instrumentation.

SUBSTANCE: scope of application: to determine geometrical displacement of sensors in flat panel detector of X-ray image. The essence of the invention is that on the work surface of the detector the test object is located, it contains at least two objects "sharp edge" corresponding to position of the process gap between the specified sensors; X-ray radiation flow is directed on the test object, its X-ray images is obtained, on the image pixels are identified that correspond to image of the sharp edge of each object "sharp edge", using them the geometrical displacement of sensors is determined on condition of objective functional minimum with limitations for the specified displacements; at that limitations include the linear limitation corresponding to the geometrical displacements of the sensors located with each other along horizontal or vertical line, and no-linear limitations corresponding to the geometrical displacements of sensors located with each other along diagonal.

EFFECT: expansion of range of technical means determining geometrical displacements of the sensors in the flat plate detector of X-ray radiation and possibility of sensor displacements determination with high accuracy.
