Cores are loaded vertically (If client has seabed marine sediment cores for instance, a vertical orientation may be preferable)
Scan A Variety of Samples
A range of attachments are provided with the VXCT system to hold a variety of core samples, or even hand specimens for analysis
Cabinet Based System
System comes fully shielded, so no need for a lead lined room!
Long life X-ray Source
Closed and sealed, long life 130kV X-ray source offered
Visualise a core’s internal structure with X-ray Imaging
The Geotek VXCT platform is a vertical X-ray scanning system, catering to clients who are imaging the sediment-water interface or have small floor areas within their lab. The system is capable of acquiring both 2D X-ray transmission images and 3D helical X-ray CT volumes to generate outputs that reveal the internal structure of a core sample.
How it works
Samples are loaded vertically and positioned aligning with the core holders. The core sample remains stationary, and the source and detector move vertically down the core to complete the scan. The flexibility of the source and detector position allows the user to achieve a voxel/pixel resolution between 30µm and 350µm. If multi-angle or full 3D CT scanning is required, the core can be rotated to your desired angle.
DATA ACQUISITION AND PROVIDED SOFTWARE – ROTATING CORE
The Geotek VXCT system is delivered with complementary software packages to allow for the visualisation, acquisition and processing of core samples. Software packages included:
Geotek X-ray acquisition software – allows the operator to set-up their scan parameters and acquire data with real-time visualisation.
Geotek GQuickView software – allows the user to view and manipulate the X-ray radiographs and CT slabs.
Geotek CTQuickView software – allows the user to view and manipulate stacked tiff image sequences to create orthogonal and unwrapped slabs
Geotek Reconstructor software – allows the user to reconstruct using helical or circular reconstruction recipes and view the core slices or generate orthogonal slabs.

The Geotek XCT system offers various acquisition modes which may be selected prior to scanning: 2D radiography, laminography and 3D CT. These are outlined below, but for further information, please see our technique pages.
Multi-angle 2D transmission images with software corrections to produce virtual slab
Quasi-3D imaging technique using tomographic reconstruction to reconstruct planes within the core
Data acquisition with tomographic reconstruction to produce axial slices and orthogonal and circumferential slabs or a 3D volume
