Basic histologic parameters
Ideal section size = 0.2 mm x · 0.2 mm y · 90 nm
Stack thickness = 0.025 mm = 278 sections (ipl) ~400 GCL > OPL
Definitions
A Canonical field is a region containing no less than
three copies of the rarest cell class. This is our ideal volume.
A Canonical tile is a region containing the rarest cell
class and its Voronoi domain.
