Description

Industrial CT mechanism

Technical Field

The invention belongs to the field of X-ray detection devices, and particularly relates to an industrial CT mechanism.

Background

The X-ray detection equipment is widely applied to the fields of food, medical detection, industrial inspection and the like, and the principle of industrially utilizing X-ray detection is as follows: when X-rays are absorbed by a substance, the molecules that make up the substance are broken down into positive and negative ions, known as ionization, and the number of ions is proportional to the amount of X-rays absorbed by the substance. The ionization effect is generated by air or other substances, and the ionization degree is measured by a meter, so that the quantity of the X-ray can be calculated. The image is converted into digital signals by an imager, and the digital signals are restored into images by computer-aided software to be subjected to image judgment, labeling, storage and the like.

Under the condition that the detected object is not damaged, the industrial CT can clearly, accurately and visually display the internal structure, composition, material and defect conditions of the detected object in the form of a two-dimensional tomographic image or a three-dimensional stereo image, and is known as the best nondestructive testing and nondestructive evaluation technology at present, so that the requirement on the measurement precision of the industrial CT is very high, and the higher the precision, the better the effect is.
