Quantifying total and activeTPB
Complete quantification of TPB length or TPB density requires access to a three dimensional dataset created by serial sectioning (e.g. serial mechanical polishing, microtoming or focused ion beam milling) or computed tomography. Using stereological methods it is possible to calculate the mathematically exact TPB density from two dimensional microscopy images by counting points in images where three phases meet, as counting points per length squared (image area) has the same units as described above.
