What is Industrial CT? What are the main technical indicators of Industrial CT?

Industrial CT is the abbreviation of industrial computed tomography, it can be in the detection of the object without damage to the conditions of the two-dimensional tomographic images or three-dimensional stereo images in the form of a clear, accurate, intuitive display of the structure of the object to be detected in the internal composition of the material and defects, known as today's best non-destructive testing technology. Industrial CT technology involves nuclear physics, microelectronics, optoelectronics, instrumentation, precision machinery and control, computer image processing and pattern recognition and other multidisciplinary fields, is a technology-intensive high-tech products. Industrial CT is widely used in automotive, materials, aerospace, aviation, military, national defense and other industrial fields, for the detection of aerospace launch vehicles and airships aviation engines, detection of large weapons, analysis of geological structures, and the quality of mechanical products is an important means of detection. Industrial CT system performance indicators 1.

Detection range: the main description of the ICT detection object. Such as the maximum thickness of transmissive steel, detection of the maximum rotary diameter of the workpiece, detection of the maximum height or length of the workpiece, detection of the maximum weight of the workpiece, etc. 2. 2.2.

The use of the ray source: the size of the X-ray energy, the operating voltage, operating current and focus size. 3.3.

The scanning mode of ICT: with which scanning modes, with or without digital ray detection or real-time imaging capabilities, etc. 4.

Scanning Detection time: refers to the acquisition time of sweeping a tomographic data.5.

Image reconstruction time: refers to the time required to reconstruct the image.6.

Resolution capability: is the key performance indicator, including:

Spatial resolution: refers to the ability to recognize the smallest object from the CT image.

Density resolution: it is the basic method of using the gray scale of the image to distinguish the material of the examined object (because the gray scale is a direct reflection of the density).

The relationship between spatial resolution and density resolution. In the case of a certain radiation dose, spatial resolution and density resolution are two contradictory indicators.
