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 X-ray sources offered in 130kV or 180kV forms
Large flat panel X-ray detector
Cores centralised by wirelessly controlled motorised arms that securely hold core samples horizontally. A range of arm attachments is provided to hold various core samples, hand specimens or even single boxes for analysis
Visualise a core’s internal structure with X-ray Imaging
The versatile Geotek XCT system allows for the acquisition of both 2D X-ray transmission images and full 3D helical X-ray CT volumes of core samples through horizontal scanning techniques. The system is available with a 130 kV or 180 kV microfocus closed X-ray source to meet different industry needs and core types. Whether lined whole core, split core, or slabbed core sections, the XCT’s flexible geometry allows for scanning cores of varying diameters. Adjustable X-ray source and detector positions can be optimised for image quality, resolution and core size.

How it works
Samples are loaded horizontally into one of the cabinet arms inside of an X-ray tube and centralised by wirelessly controlled motorised arms. The core sample translates through the centre cabinet past a fixed source and detector position that the user has selected, and can be rotated under computer control to examine internal structures at various angles. The flexibility of the source and detector positions allows the user to achieve a voxel/pixel resolution between 35 microns and 300 microns on the XCT.
DATA ACQUISITION AND PROVIDED SOFTWARE – ROTATING CORE
The XCT system rotates the core sample to create the three-dimensional data set. Core can be rotated under manual or computer control to examine structures or collect rotational movies. Core rotation allows visualisation of three-dimensional features by the operator and choice of optimum scanning orientation.
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
3D Helical CT
Helical data acquisition with tomographic reconstruction to produce axial slices and orthogonal and circumferential slabs or a 3D volume
