The paper evaluates a compact LED-based radiometric emitter for SI-traceable radiance transfer, finding stable radiance and responsivity across varying distances and apertures.

This paper characterizes indocyanine green (ICG) excitation-emission matrices in different microenvironments, showing excitation-dependent emission and its implications for fluorescence-guided surgery.

This paper develops a radiometric framework to convert device-native fluorescence counts into SI-traceable radiance and fluorescence yield, enabling reproducible quantitative imaging.

This paper introduces a phantom and analysis code to assess fluorescence uniformity and distortion in surgical imaging systems, finding that flat-field correction improves image appearance but may reduce quantitative accuracy.
