Artificial intelligence based real-time microcirculation analysis system for laparoscopic colorectal surgery

Figure 4 Results of good perfusion patient with small T_max, large F_max, and steep indocyanine green curve. A: White light image; B: Indocyanine green (ICG) fluorescence image, very well observed; C: Color map result of artificial intelligence method; D: Color map result of T_1/2max method; E: Color map result of time ratio method; F: Color map result of rising slope method; G: Average ICG curve. The results of all methods were the same as risk-safe. TR: Time ratio; RS: Rising slope; ICG: Indocyanine green; AI: Artificial intelligence.
