Kinetics of Transient Tissue Transparency (T3RIE)
After establishing transient optical clearing in living tissue, this work focused on a key next question: how does transparency change over time in vivo? We developed complementary optical approaches to quantitatively monitor these dynamics in living animals.
- Used an implanted self-illuminating light source to directly quantify changes in transmitted intensity and light-source profile width during T3RIE.
- Combined visible and NIR imaging to develop a non-invasive reflectance-based method for monitoring transparency and anatomical image contrast over time.
- Compared in-vivo and ex-vivo kinetics to distinguish physiological transparency dynamics from changes intrinsic to the clearing agent alone.
