Area of Science:

  • Biomedical Engineering
  • Regenerative Medicine
  • Medical Imaging

Background:

  • Tissue engineering advancements are moving towards clinical applications, but manual laboratory procedures limit scalability.
  • Routine clinical practice requires automation, scale-out processes, and reliable on-line monitoring systems.
  • Real-time in vitro monitoring of flow characteristics in growing tissues is critical for quality control.

Purpose of the Study:

  • To review the current status of Doppler optical coherence tomography (DOCT) for in vivo applications.
  • To report the preliminary use of DOCT for in vitro monitoring in tissue engineering.
  • To assess the feasibility of DOCT for real-time flow characterization in engineered tissues.

Main Methods:

  • Review of existing in vivo applications of Doppler optical coherence tomography (DOCT).
