Computed Tomography01:10

Computed Tomography

4.7K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Electron Microscope Tomography and Single-particle Reconstruction

2.5K
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.

X-ray Diffraction of Biological Samples

3.9K
X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are  scattered by the electron clouds around the sample atoms. The  X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

Area of Science:

  • Medical Physics
  • Materials Science
  • Geology

Background:

  • Dual-energy computed tomography (DECT) enables material discrimination by reconstructing electron density (ρe) and effective atomic number (Zeff) distributions.
  • The conventional image-domain basis material decomposition (IBMD) method faces limitations in direct mineral identification due to complex basis material determination, beam hardening artifacts, and empirical formula inaccuracies.

Purpose of the Study:

  • To develop an improved IBMD (IIBMD) method for overcoming the limitations of conventional IBMD in mineral identification.
  • To enhance the accuracy of ρe and Zeff distribution reconstruction for precise mineralogical analysis.

Main Methods:

  • Optimized basis material composition and thickness in the IIBMD method to improve decomposition coefficients and mitigate beam hardening.
  • Introduced novel formulas for calculating ρe and Zeff, replacing approximate empirical formulas.
  • Applied a threshold technique for effective separation of different mineral phases.

Main Results:

  • Numerical simulations and photon-counting detector CT experiments validated the IIBMD method.
  • Achieved relative errors as low as 5% for ρe and Zeff in seven common minerals, outperforming existing DECT methods for rocks.
  • Obtained accurate mineral phase volume fractions through threshold segmentation.

Conclusions:

  • The proposed IIBMD method demonstrates significant practical value for mineralogical identification.
  • The IIBMD method offers a more accurate and reliable approach for material decomposition in DECT applications.
