Scanning bed and Micro CT imaging system

Abstract

The invention relates to a scanning bed and a Micro CT imaging system, the scanning bed comprises an interface part and a bed body, the bed body extends outwards from the interface part, the bed body is provided with a plurality of bearing grooves, the plurality of bearing grooves are coaxially arranged along the length direction of the bed body, and at least two bearing grooves are different in size. In the scanning bed, the plurality of bearing grooves are formed, and at least two bearing grooves are different in size, so that the bearing groove with the proper size is selected according to the size of the scanned object, the scanned object can be placed at the circle center of the arc-shaped bearing groove, and the axis of the bearing groove and the center of the imaging FOV are located on the same straight line; and therefore, the scanning object is placed in the center of the imaging FOV, and the scanning processing efficiency is improved while the high image quality is ensured.

Description

technical field [0001] The invention relates to the technical field of scanning imaging, in particular to a scanning bed and a Micro CT imaging system. Background technique [0002] In the field of life science or material science, it is necessary to use Micro CT (micro CT, also known as micro CT, micro focus CT, CT: Computed Tomography, electronic computer tomography) imaging system to detect some mice and mouse tissues of different sizes. Organs (such as trabecular bone, mouse legs, teeth), zebrafish, and tissues of various specifications are scanned. Micro CT generally uses a micro-focus X-ray tube different from ordinary clinical CT, which can scan and analyze small living animals or various hard tissues and related soft tissues. Its resolution can be as high as several microns, second only to synchronous The level of accelerated X-ray imaging equipment has a good "microscopic" effect. [0003] In order to ensure higher image quality (such as resolution), it is necessa...

Problems solved by technology

When switching between scanning objects with large size differences, it is usually necessary to switch scanning beds of different sizes to fit the scanning objects, adjust the scanning objects to the scanning center, or use materials with low X-ray (X-ray) absorption coefficients to The sample is padded so that the sample is placed in the center of the FOV. This process will inevitably reduce the efficiency of scan preprocessing
