血管内荧光寿命成像
Intravascular Fluorescence Lifetime ImagingA non-invasive optical imaging technique that measures the fluorescence lifetime of endogenous or exogenous fluorophores within the vascular wall to assess tissue composition and pathology. / 一种非侵入性光学成像技术，通过测量血管壁内内源性或外源性荧光团的荧光寿命来评估组织成分和病理。

Main parameters and performance indicators
Fluorophore: Endogenous (e.g., NADH, FAD) or exogenous contrast agentsExcitation Wavelength: Typically UV or visible lightTime-Resolved Detection: Measures decay time (nanoseconds) rather than intensity
Open problems
Integration with real-time catheter navigation systemsStandardization of lifetime thresholds for specific tissue typesMinimizing motion artifacts during cardiac cycles
