The SkyScan 1174 is a compact, low-cost, portable X-Ray scanner for nondestructive three dimensional microscpy. X-Ray tomography system alows to visualize and measure complete three-dimensional object structures and without sample preparation or chemical fixation. We can describe the X-ray illumination as parallel. In this approximation, each point on the shadow image contains the integration of absorption information inside the three-dimensional object along the path of the corresponding partial X-ray beam. For parallel geometry one can divide the problem of three-dimensional reconstruction from two-dimensional projections into the serial reconstruction of two-dimensional object slices from one-dimensional shadow lines. SkyScan 1174 can be connected to any Pentium-based PC by serial port or USB & FireWire. The 1174 is supplied with software for system control, X-ray radiography and 3D reconstruction. The main areas of application are metal foams, plastics, composites, diamonds defectoscopy, biomedical objects and other non-destructive testing. Specifications Object size – 5 – 30 mm in diameter, 50 mm in length (50 mm vertical travel), X-ray source – 20-50 kV, 40 W maximum power, filter holder for energy selection, X-ray detector - 1280 x 1024 x 12 bit digital x-ray camera with coupling P43 scintillator screen by motorized zoom macro lens, Spatial resolution – 6 - 30 µm pixel size, approximately 10µm low-contract resolution, Scanning time – typicaly 2 – 15 min for 512 x 512 x 512 pixels volume or 5 – 40 min for 1024 x 1024 x 1024 pixels volume, Radiation safety - < 1 μSv/h in any place of instrument surface. In SkyScan systems, using a Windows environment, the results of scanning can be saved in BMP (8 bit) or TIFF (16 bit) formats.
