Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] like figure 1 as shown, figure 1 for the present invention.

[0031] A 3D imaging system for industrial CT, including an X-ray generator set opposite to each other, an arc detector 8, a first conveyor belt 5 and a second conveyor belt 1 arranged on the same axis, the first conveyor belt 5 and the There is a gap between opposite ends of the second conveyor belt 1 , and the X-ray generator and the arc detector 8 are arranged to rotate around the first conveyor belt 5 and the second conveyor belt 1 with the gap as a center.

[0032] Preferably, the X-ray generator includes an X-ray tube 6 and a beamer 7, the beamer 7 is installed at the light outlet of the X-ray tube 6, and the beamer 7 faces the imaging mark The point is set opposite to the incident window of the arc detector 8 .

[0033] Preferably, the X-ray tube 6 and the arc-shaped detector 8 are...

Abstract

The invention provides a 3D imaging system and method of an industrial CT. The imaging system comprises an X-ray generator, an arc-shaped detector, a primary conveyer belt and a secondary conveyer belt, wherein the X-ray generator and the arc-shaped detector are opposite to each other; the primary conveyer belt and the secondary conveyer belt are arranged on the same axis; a gap is formed between the opposite ends of the primary conveyer belt and the secondary conveyer belt; the X-ray generator and the arc-shaped detector are arranged in a manner of rotating around the primary conveyer belt and the secondary conveyer belt by taking the gas as the circle center. Through longitudinal section type scanning of the 3D imaging system, relatively long objects such as long-columnar objects of dozens of centimeters to dozens of meters as well as internal materials, meters and elements such as water suction pumps, water conservancy generators, aviation undercarriages, aviation engines, diving gears, underwater searching and rescuing devices, bridge components, aerospace vehicles and underwater moving devices can be relatively easily checked by using the 3D imaging method.

Description

technical field [0001] The invention relates to the field of CT imaging, in particular to a 3D imaging system of industrial CT and a 3D realization method of industrial CT. Background technique [0002] At present, industrial non-destructive three-dimensional 3D detection mostly adopts the form similar to medical CT. The item is placed on the conveying device, and the linear array detector and the ball tube rotate at a certain angle (such as 2 degrees) up and down the item to take a two-dimensional X-ray film and rotate it for a circle. Afterwards, data reconstruction is performed on the 180 two-dimensional X-ray films taken, and a slice image of the object with a certain thickness (such as 1 mm) is obtained. The object moves forward for a certain distance (such as 2 mm), and then the above-mentioned rotation filming is performed. Obtain the X-ray slice image at this position, and continuously move the item forward to take pictures to obtain a series of slice images of a cer...
