Method for inspecting object using multi-energy radiations and apparatus thereof
First Claim
1. A method for inspecting an object using multi-energy radiations comprising the steps of:
- causing multi-energy radiations to interact with an object under inspection;
detecting and recording detection values after an interaction between the multi-energy radiations and the object under inspection;
substituting a portion of the detection values into a predetermined calibration function to obtain information comprising primary material attribute; and
determining further material attributes of the object by applying a set of functions suitable for a energy band corresponding to the information.

Abstract
The present invention discloses a method for inspecting an object using multi-energy radiations and an apparatus thereof. The method comprises the steps of: causing multi-energy radiations to interact with an object under inspection; detecting and recording detection values after an interaction between the multi-energy radiations and the object under inspection; substituting a portion of the detection values into a predetermined calibration function to obtain information comprising primary material attribute; and determining further material attributes of the object by applying a set of functions suitable for a energy band corresponding to the information. The present invention is applicable to the large container cargo inspection without opening containers at customs, ports and airports.

15. A method for inspecting an object using multi-energy radiations comprising the steps of:
-
causing multi-energy radiations to interact with an object under inspection;
detecting and recording detection values after the interaction between the multi-energy radiations and the object under inspection, and forming images corresponding to the X-rays having different energy levels;
substituting a part of the detection values into a predetermined calibration function to determine the mass thickness of the object; and
selecting weighting factors for the detection values based on the mass thickness to combine the images so as to obtain more accurate gray-scale image. - View Dependent Claims (16, 17, 18, 19)
