Morphometry error due to non-perpendicular section of microvessel characterized by two-dimensional isotropic arrangement.
Formulas for calculation of the section non-perpendicularity error in estimation of the perimeter and cross-sectional area of microvessel profiles are proposed for the two-dimensional isotropic approximation. A relationship was established between the bias and random error associated with non-perpendicularity corresponding to theta(min) for microvessel profiles meeting the condition theta(min) < or = B/C < or = 1, where B and C are the minimum and maximum axes of the microvessel profile, respectively.
