Description
Technical field
The present invention relates to a kind of sample preparation methods, and in particular to a kind of Micro-CT scanning Multi-example preparation facilities and user
Method.
Background technology
Micro-CT scanning（Micro-Computed Tomography）, X-ray microfault photography is also referred to as, refers to space point
Resolution can reach the CT of lum or so.The main composition of Micro-CT scanning includes X radiographic sources, specimen rotating holder and high-resolution and visits
Survey three parts of device.X-ray source and detector are fixed, and sample rotates between X radiographic sources and detector, are produced by X radiographic sources
Raw continuous taper X beams penetrate sample to be tested, are imaged on X-ray detector.By rate at an angle to sample
Product are rotated, and obtain x-ray perspective view of the sample in different angle.By corresponding computer software, by each angle
Projected image be reconstructed, be reduced into the analyzable 3D rendering in computer.In order to reach higher resolution ratio, when rotating
Step-length it is smaller, the time for exposure is longer, while in order to improve clarity and accuracy, each angle gathers the progress of multiple images
Image co-registration and correction, so the parameter testing of Micro-CT scanning and image acquisition time are all very long.In daily microscopic CT scanning point
During analysis, if only making a sample every time, scan efficiency can be made very low, frequently switch on ray and sample door, to the damage of instrument
Consumption is also bigger.So in order to save the time, raising testing efficiency often will be to several samples similar in X-ray absorption coefficient
It is put on a sample stage and is carried out at the same time test.Due to the limited area of the CCD or other detectors that are used for Image Acquisition, in order to
Limited（CCD）It observes within sweep of the eye as far as possible big（It is more）Sample volume（Quantity）, it is necessary to as far as possible ensure sample to
The axle center set of instrument turntable.Since instrument turntable is relatively large in diameter, sample needs to pass through the support concentric with turntable
Bar connects turntable.Therefore, sample must try one's best the center line set to sample support bar, and rotating diameter is straight no more than supporting rod
Footpath.Due to current Micro-CT scanning negligible amounts, sample preparation device is few, and conventional sample preparation means easily make sample beyond support shank diameter model
It encloses, success rate is not high, it is impossible to meet the Multi-example rapid prototyping requirement of Micro-CT scanning.
