Researchers developed a method to continuously adjust the field of view in X-ray micro-CT scanners by displacing the detector array. This technique allows for artifact-free reconstruction across various sample sizes.

Area of Science:

  • Medical Imaging
  • Physics
  • Engineering

Background:

  • X-ray micro-computed tomography (micro-CT) is crucial for analyzing samples of varying sizes.
  • Adjusting the field of view (FOV) is essential for optimal micro-CT imaging.
  • Current methods for expanding FOV, like 50% detector displacement, are limited.

Purpose of the Study:

  • To introduce a novel method for continuously adjustable field of view in micro-CT.
  • To develop a weighting scheme for artifact-free image reconstruction with partial detector displacement.
  • To validate the proposed method through numerical simulations.

Main Methods:

  • Proposing detector array displacement between 0% and 50% for adjustable FOV.
  • Formulating a weighting scheme to mitigate reconstruction artifacts.
