Paper Abstract

An x-ray microtomograph (or micro-CT) is an instrument for nondestructive 3-dimensional reconstruction of the object's internal microstructure without physical cut or time consuming specimen preparation. By using modern technology in x-ray sources and detectors several micro-CT systems were created as a simply usable desktop instrument. First micro- CT system is a laboratory instrument, giving true spatial resolution over ten million times more detailed (in the term of volume parts) than the medical CT-scanners. The instrument contains a sealed microfocus x-ray source, a cooled x-ray digital CCD-camera and a Dual Pentium computer for system control and 3D reconstructions running under Windows 2000. The instrument includes possibilities for image analysis in the nondestructively reconstructed internal microstructure and realistic 3D visualization. During scanning, objects are displaced in normal environment conditions, without vacuum or preparation. Another micro-CT scanner is a low-cost portable instrument, which can be connected to any external Pentium-based PC. Third instrument - microlaminograph - can create nondestructive slicing in any place of big planar objects (electronic assemblies, PCBs, etc.). This system uses principles of tomosynthesis from incomplete dataset for slicing in internal object's layers. The main application areas for micro-CT and microlaminography systems are biomedical research, material sciences, electronic components, etc.
