OCM images of vascularity and structure of the GBM tumor after 14 days in mouse M1. (a-d) angiomaps with dimensions of 2.8 × 2.8 mm presenting blood vessels taken from four depths; (a) 0-50 um, (b) 50-100 um, (c) 100-200 um, (d) 200-300 um. Blue stars depict specific for glioma loops of newly formed vessels; red star indicates another abnormality of vessel appearance; red arrowheads delimit border of the tumor. (e) Angiographic B-scan (2.8 × 0.4 mm) reveals signals from vessels with blood flow on different depths of the tumor area. (f) Structural B-scan (2.8 × 0.4 mm) demonstrates scattering signal characteristics for the tumor. The red arrow shows a needle trace where glioma cells were delivered.
