Xradia Zeiss VersaXRM-520: The 520's create 3D datasets with a voxel size in a continuous range between 150nm and 50 microns. Using proprietary interchangeable focusing optics allows users to locate and scan small sub-regions within a specimen as large as 30 cm in height and 30 cm in diameter. This feature is unique among micro-CT devices, which typically have strict limits on the physical size of a specimen. The focusing capability is particularly useful for examining specimens that are too rare or delicate to be sectioned destructively (fossils, museum specimens, exotic materials). 4D/5D+ datasets can be created via repeated scanning of the same specimen (e.g. before/after treatments, temperature changes, pressure changes, etc).
This instrument is used to visualize and measure structues in plants, insects, seeds, fossils, electronic or microfluidic devices, foods, fabrics, material constructs, soft or dense biological tissues, archaeological artifacts, etc.
GE eXplore CT-120: The micro-CT system has the same non-invasive capabilities and is generally used for faster and lower radiation dose/lower resolution scans. The 120 can acquire data with voxels ranging from 25um-100um. It has an 8cm diameter bore which can accommodate live animals, plants, fossils, etc. In this system the x-ray source and detector rotate around the bore so that the specimen can remain stationary. Oboard anesthesia and cardiac and respiratory gating are available for live animals. Appropriate specimen and studies include: live vertebrate and invertebrate animals (e.g. during/after a treatment, at various stages of developmental morphogenesis, etc), insects, plants, fossils, electronics, and materials.
