SkyScan 1172 Micro-CT
Micro-CT Scanner with Adaptive Geometry
The SkyScan 1172 represents a new generation in high-resolution desktop X-ray microtomography (Micro-CT) systems for in vitro scanning. The combined ability of the sample stage and the x-ray camera to move is a novel architecture which allows for an unprecedented combination of image resolution, sample size accommodation, scan speed and sample throughput. The innovative scanning geometry of the SkyScan 1172 Micro-CT is particularly advantageous at intermediate resolution levels, where scans are completed up to ten times faster with the same resolution and image quality, compared to previous Micro-CTs with a fixed source-detector design.

Adaptive Geometry - A bright idea in microtomography
Using Adaptive Geometry, the Skyscan 1172 Micro-CT adjusts the distance between the X-ray detector and source for the optimum position for a given scan. A majority of scans can be performed with the detector closer to the source for higher intensities on the detector which means faster scan times and more throughput for you. When you need higher resolution (below 4 microns) or a larger field of view, the Skyscan 1172 Micro-CT moves the detector to the far position. Adaptive Geometry gives you the flexibility to manage workflow without compromising resolution.
Introduction to X-ray Microtomography (Micro-CT)
Microtomography uses a similar technique as X-ray tomography systems used in medicine (CT Scans) but with much finer resolution. Multiple 2D X-ray images are stored while either the sample or the source / detector pair is rotated. Internal structures are reconstructed as a series of 2D cross sections (up to 2600 in a single scan) which are then used to analyze the two and three dimensional morphological parameters of the object. The process is non destructive and requires no special preparation of the specimen. For comparison, medical CT systems have pixel sizes in the range of 1mm, the Skyscan 1172 Microtomograph can acquire images with 0.7 micron pixel size.
The powerful imaging capabilities of X-ray tomography are now available in a range of desktop instruments suitable for microscopic imaging of small objects with a wide range of applications: 3D bone analysis, food studies, soft tissue research, insects, microelectronics, materials, geological studies and more. Specialized software (CTAn) has been developed for the analysis of Micro-CT images including bone morphometry, porosity, fractal analysis and more (see related pages).
