A principle for counting tissue structures on random sections

Weibel, Ewald R., Gomez, Domingo M.·1962·Journal of Applied Physiology

Abstract

A new principle is derived from mathematical considerations which will allow the calculation of the number of bodies contained in the unit volume by counting the number of transections on the unit area of a random section. The simple equation involves two coefficients related to the volumetric density of the bodies in the volume, and to their configuration. Means for the accurate determination of these coefficients are given. The verification of this principle in model experiments showed a high degree of reliability of the method with average errors of estimate of 2–4%. The method has been applied to the counting of alveoli in five normal human lungs, which were found to number an average of 300 million, with a striking constancy from lung to lung. Submitted on May 31, 1961

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
