Figure Lengend Snippet: Schematic representation of the data acquisition process during colorectal surgery. Measurement of the pre-cube was performed with the TIVITA Tissue (Diaspective Vision, Am Salzhaff, Germany) prior to administration of ICG. Real-time recording of the fluorescence signal of ICG after its injection was performed using the EleVision IR Platform (Medtronic, Minneapolis, USA). The post-cube containing spectral information of ICG was acquired afterward.

Figure Lengend Snippet: RGB (A), ICG (B), and StO2 (C) image compared with reconstructed ICG signals (D-I) for one selected patient. A and C were generated from the post-cube (TIVITA Tissue). B represents the last frame of the ICG video (EleVision IR Platform). D-F show the results of the difference method, G-I those of the post-cube method. The reconstructed images were visualized with a green-shaded overlay of the RGB image (D, G), an 8-bit gray scale (E, H), and color-coding analogous to the TIVITA Tissue system (F, I). In A, the position of the fixed point PF is shown as the tip of the tweezer. In B and C, the central and distal points (PC and PD, respectively) were additionally visualized. Both were used to determine the width of the boundary zone wCD according to C.
