Abstract

Desktop microtomography is a new hi-tech tool for non-destructive testing in different application areas. Similar to the equipment associated with body scans used in hospitals or industrial CT-scanners, the new system is only a fraction of the size. The system comprises a 80 kV / 100ľA or 130kV / 300ľA X-ray sealed tube with 8-10 microns spot size, a multi-axle object manipulator, an X-ray CCD-camera with on-chip integration and powerful computer with software for system control and microtomographical reconstruction. The system capable of seeing down to 3-10 microns objects with possibilities of3D-reconstruction with 10 microns accuracy of locations. A single cross section as well as complete 3D internal structure can be reconstructed after one complete object scan. During investigation the specimen displaced in natural conditions with no need for any preparation. With fastest Windows-NT software package the reconstruction speed was 14 see per cross section of 512x512 pixels (Dual Pentium-Pro 200Mhz). Powerful image processing and analysis possibilities integrated into the software package. It allows calculating the numerical characteristics of object's internal structure non-destructively. Visualization possibilities contain of cross section displaying and demonstration of complete 3D-object onto the screen with rotation and customized cut.
Main areas of application are electronic components, material science, medicine, biology, geology, diamond industry and various R&D applications.
