Introduction

Industrial ray computed tomography detection (referred to as industrial CT) is obtained by ray projection measurement of objects at different angles: The imaging technology of object cross-section information involves many disciplines such as radiation physics, mathematics, computer science, graphic imaging and mechanics: Industrial CT has the advantages of not being limited by the type of material, composition, surface condition, etc: of the measured object, and can give the composition, density, geometric The tomographic images corresponding to the structure and size characteristics are characterized by intuitive imaging, high spatial and density resolution, and have been widely used in aerospace, aviation, etc: Air, weapons, metallurgy, machinery, automobile manufacturing, high-speed rail, electronics, geology, biology, archaeology and other fields, for defect detection, size measurement, density meter characterization, assembly structure analysis, reverse engineering and other occasions: In order to standardize the inspection work of industrial CT and be in line with international standards, on the basis of summarizing the experience of industrial CT research and application over the years, the ISO 15708 (a total of four parts) is converted into my country's standard documents, of which ISO 15708-1 is modified and converted into GB/T 12604:12 "No NDT Terminology Part 12: Industrial X-ray Computed Tomography Inspection, included in the standard system of NDT terminology in my country: ISO 15708-2~ISO 15708-4 are equivalently converted into GB/T 41123 series of documents: GB/T 41123 consists of 3 parts: --- GB/T 41123:1 Non-destructive testing of industrial ray computed tomography testing - Part 1: Principles, equipment and samples; --- GB/T 41123:2 Non-destructive testing of industrial ray computed tomography testing - Part 2: Operation and interpretation; --- GB/T 41123:3 Non-destructive testing of industrial ray computed tomography testing - Part 3: Verification: GB/T 41123 specifies the principles, equipment and samples, operation and interpretation, verification, etc: of industrial CT: Cheng put forward quality control requirements, which is conducive to promoting the development, exchange and cooperation of industrial CT technology, and has great significance for the application of industrial CT in various industries: important guiding significance: This document is part 1 of GB/T 41123, which specifies the general principles of X-ray computed tomography (CT), the equipment used And basic notes about samples, materials, and geometry: Nondestructive Testing Industrial Radiography Computed Tomography Testing Part 1: Principles, equipment and samples

1 Scope

This document specifies the general principles of X-ray computed tomography (CT), the equipment used and information on samples, materials and geometries Basic considerations: This document is applicable to industrial computed tomography (non-medical applications) detection and defines a set of CT system performance parameters, as well as these properties: Relationship between performance parameters and CT system specifications: This document applies to computed axial tomography and does not apply to other types of tomography such as translational tomography and tomosynthesis imaging:
