Role of Delta

Table of produced number of Tetrahedra for certain values of delta using the image: Brain-With-Tumor-Case17.

The size of the input image is: (512x512x119) Spacing of the input image: (0.27734,0.27734,1)

MinimumPhysicalSize = 119 * 1 = 119 Max value that possibly will not cause problems is: 119 / 5 = 23.8
