Research Summary:

Dr. Yang is well-recognized for his work in advanced fibre-optical probes for imaging tissue microstructure and microcirculation. His work has led to the development of new diagnostic imaging and therapeutic monitoring tools for minimally invasive procedures.

Dr. Yang's research has:

  • improved catheter designs and developed new methods for Doppler optical coherence tomography (OCT) in interstitial, intravascular and endoscopic studies
  • developed speckle variance as a tool for microvasculature detection using swept source OCT
  • developed high power polygon filter-based Frequency Domain Mode Lock (FDML) tunable laser sources for OCT
  • developed Yb-doped fibre gain element for high power multichannel OCT
  • demonstrated multichannel OCT for in vivo imaging
  • used ultra-short pulsed laser ablation in hard tissues for inline coherent imaging
  • developed tools to detect cell death with spectroscopic OCT
  • used artificial muscle actuation for catheter-based OCT imaging 
  • conducted an in vivo preclinical trial of endovascular OCT imaging of carotid artery.
