A new fiber-optic-bundle Optical Coherence Tomography (OCT) probe was developed. This compact, moving-part-free system achieves high resolution for internal organ imaging.

Area of Science:

  • Biomedical Engineering
  • Optical Imaging
  • Medical Devices

Background:

  • Optical Coherence Tomography (OCT) is a valuable non-invasive imaging technique.
  • Traditional OCT probes often involve complex moving parts, limiting miniaturization and safety.
  • There is a need for compact, robust OCT systems for endoscopic applications.

Purpose of the Study:

  • To present a novel fiber-optic-bundle-based Optical Coherence Tomography (OCT) probe.
  • To demonstrate the feasibility of a moving-part-free OCT probe design.
  • To evaluate the imaging performance of the developed OCT system.

Main Methods:

  • Utilized a multimode optical fiber bundle for OCT probe construction.
  • Employed a superluminescent diode as the light source.
