Optical coherence tomography elastography (OCTE) offers a new way to measure tissue elasticity at the micron level. This study shows OCTE is feasible for evaluating phantom and arterial tissue mechanical properties.

Area of Science:

  • Biomedical Engineering
  • Medical Imaging
  • Materials Science

Background:

  • Assessing tissue mechanical properties is crucial for disease diagnosis.
  • Current methods may lack micron-scale resolution or invasiveness.
  • Optical coherence tomography (OCT) offers high-resolution imaging.

Purpose of the Study:

  • To evaluate the feasibility of OCT elastography for measuring tissue elastic properties.
  • To assess the mechanical characteristics of phantoms and atherosclerotic arterial samples using OCT elastography.

Main Methods:

  • Utilized optical coherence tomography (OCT) for elastography.
  • Measured elastic modulus of tissue-mimicking phantoms.
  • Correlated OCT elastography measurements with established mechanical testing methods.
