DYNAMIC COLLIMATION OF EMISSION FOR NON-DESTRUCTIVE ANALYSIS OF TEST OBJECTS Russian patent published in 2022 - IPC G01N23/46 

FIELD: imaging.

SUBSTANCE: use: generation of tomographic data of a test object. The substance of the invention consists in the fact that, for each corresponding rotary position of the first phase from a set of rotary positions of the first phase, the visualisation system can generate a corresponding image of the first phase. Based on the identified area of interest in the corresponding image of the first phase, the visualisation system can determine the positions of collimator plates for the corresponding rotary position of the first phase. For each corresponding rotary position of the second phase from a set of rotary positions of the second phase, based on the positions of collimator plates for the rotary positions of the first phase, the visualisation system can determine the positions of collimator plates for the corresponding rotary position of the second phase . The visualisation system can generate the corresponding image of the second phase in a second sequence of images at a time when the test object is in the corresponding rotary position of the second phase, and at a time when the collimator plates are in the positions of collimator plates for the corresponding rotary position of the second phase. Based on the second sequence of images, the visualisation system can calculate the tomographic data for part of the test object.

EFFECT: increase in the quality of tomographic images.
