Title:
DUAL-ENERGY RADIATION SYSTEM AND METHOD FOR INCREASING MATERIAL IDENTIFICATION CAPABILITY OF DUAL-ENERGY RADIATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/188637
Kind Code:
A1
Abstract:
A method for increasing the material identification capability of a dual-energy radiation system and the dual-energy radiation system. The method comprises: implementing dual-energy scan-detection on a test sample of a first type and of a first thickness, when detected data is inconsistent with the test sample, adjusting the pulse number ratio or pulse dose ratio of the dual-energy radiation system until the detected data is consistent with the test sample, and using this as the working ratio of the dual-energy radiation system when formally scanning. The method allows acquisition of the optimal material identification state of the dual-energy radiation system; with scan-inspection being performed in this state, the material identification capability of the dual-energy system is substantially improved.
