RXCT: Rotating X-ray CT System

The RXCT system is Geotek’s most flexible X-ray imaging platform, and is capable of acquiring 2D X-ray radiographs as well as full 3D CT volumes. This system was specifically designed for fragile core that cannot be rotated.. Whether your core is highly fractured, friable, or rubbly, the rotating source and detector mean that you can visualise and record three-dimensional structures within your samples, no matter what their condition.

DATA ACQUISITION AND PROVIDED SOFTWARE – ROTATING SOURCE

The Geotek RXCT system is delivered with complementary software packages to allow for the visualisation, acquisition and processing of core samples. The data can be visualised and combined with MSCL data to acquire a greater understanding of the internal structures within the core sample.

  • 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.

Acquisition Modes

The Geotek RXCT 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.

  • 2D Radiograph

    • Multi-angle 2D transmission images with software corrections to produce virtual slab

  • 3D Laminography

    • Quasi-3D imaging technique using tomographic reconstruction to reconstruct planes within the core

  • 3D CT

    • Data acquisition with tomographic reconstruction to produce axial slices and orthogonal and circumferential slabs or a 3D volume
