报告简介:


Optical Coherence Tomography (OCT) is an established medical imaging technology which is analogous to ultrasound imaging but has significantly higher resolution (~10 m) to enable 3D imaging of tissue microstructures in situ and in real-time with a penetration depth of ~1-2 mm. OCT can be extended to functional imaging modalities such as Doppler OCT (DOCT) for blood flow detection and polarization-sensitive OCT (PS-OCT) for detection of tissue birefringence. We have developed a forwarding-imaging needle-type OCT probe for avoiding the hemorrhage and guiding neurosurgical interventions. The needle probe has a thin diameter of 0.7 mm. The feasibility of vessel detection and neurosurgical guidance were demonstrated on sheep brain in vivo and human brain ex vivo. In addition, we further reduced the probe size to 0.3 mm using an optical Doppler sensing (ODS) fiber probe that can integrate with microelectrode recording (MER) to detect the blood vessels lying ahead to improve the safety of this procedure. We further combine highresolution OCT with large-field-of-view magnetic resonance imaging (MRI) to provide multi-scale imaging.
