Computed Tomography01:10

Computed Tomography

4.5K
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...

Magnetic Resonance Imaging

5.2K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Area of Science:

  • Medical Imaging
  • Computational Imaging
  • Biomedical Engineering

Background:

  • Tomographic imaging modalities rely on large system matrices, which are degraded by sparse sampling and tissue motion, impacting image quality.
  • Existing methods often enhance image quality without directly correcting the underlying system matrices.

Conclusions:

  • The developed methods significantly improve image quality in photoacoustic computed tomography.
  • The approach is broadly applicable to other tomographic modalities like X-ray CT and MRI, addressing challenges from sparse sampling, motion, and other system imperfections.
