Fig. 12. Comparison of velocity frequency distribution for core and rim regions of interest.
The regions which are extracted from the rim and the core of the tumor are presented color-coded by perfusion velocity (mm/s). The probability density distributions of velocities can be described by a gamma function for all regions. (a) Inset table comparing the velocity distributions with the two-sample K-S test. View of the vascular network annotating the position of rim regions (b) and core regions (c). Scale bars: 1 mm.
