X-ray computed tomography (xct)

  • What is an XCT?

    X-ray computed tomography (XCT) produces a three-dimensional (3-D) computer model of the imaged volume of a sample.
    Contrast between different components is based on how strongly they absorb X-rays, which is typically a function of elemental composition and density..

  • What is the principle of XCT?

    The XCT principle is based on generating .

    1. D radiographs by impinging a beam of X-rays from the X-ray tube through a sample.
      2. Further, a CCD (Charge Coupled Device) detector receives a large number of radiographic (projection) images at different angular positions during a 360\xb0 rotation of the sample.

  • What is the resolution of XCT?

    X-ray computed tomography (XCT) with cone beam geometry has become a very important method for non-destructive .

    1. D-characterisation and evaluation of materials.
      2. Compact XCT systems can reach resolutions down to 1 \xb5m and even below.

  • What is XCT imaging?

    X-ray computed tomography (XCT) produces a three-dimensional (3-D) computer model of the imaged volume of a sample.
    Contrast between different components is based on how strongly they absorb X-rays, which is typically a function of elemental composition and density..

  • The technology uses an X-ray cone beam, which will pass through the sample to a detector.
    The sample volume which it penetrates will affect the detected signal.

    1. D slice is made by rotating the sample (or the beam and detector) 180 to 360 degrees to make a series of projection images

Oct 3, 2018XCT is an approach that utilises X-rays in a similar manner to conventional X-ray radiography, generating a set of radiographs of the object 
The XCT takes a normal X-ray projection of an object, just like the X-ray pictures made of your teeth in the dentist's office, but then the sample is rotated through many small angular increments and hundreds or thousands of such projections are made.

X-ray computed tomography (XCT) is demonstrated for quality inspection of micro-injection mouldings and soft-tool deformation. XCT results compared against laser-scanning confocal microscopy. The approach provided an in-line quality predictive model up to 92% accuracy for filling prediction.
