![]() ![]() The fluorescence tests were able to assess differences in the detectable concentrations of ICG with sensitivity differences >10× for preclinical and clinical systems. Results: Imaging of the ICG-matching phantoms with all four commercially available systems showed the ability to benchmark system performance and allow for cross-system comparisons. Comparisons were completed with a range of systems that have significantly different imaging capabilities and applications, including the Li-Cor ® Odyssey, Li-Cor ® Pearl, PerkinElmer ® Solaris, and Stryker ® Spy Elite. There is a compelling need to be able to independently characterize system performance and allow for cross-system comparisons.Īim: The goal of this work is to expand on previous proposed fluorescence imaging standard designs to develop a long-term stable phantom that spectrally matches ICG characteristics and utilizes 3D printing technology for incorporating tissue-equivalent materials.Īpproach: A batch of test targets was created to assess ICG concentration sensitivity in the 0.3- to 1000-nM range, tissue-equivalent depth sensitivity down to 6 mm, and spatial resolution with a USAF test chart. ![]() ![]() Significance: Expanded use of fluorescence-guided surgery with devices approved for use with indocyanine green (ICG) has led to a range of commercial systems available. ![]()
