Studies on quantitative morphology. VIII. Model-type calculations for thyroid gland morphometry.
A sphere with a nucleus and a shell each with different tissue component distributions was used as an approximative model for the thyroid gland. Noticeable divergencies are often seen between the composition of the total body and single parallel sections through such a sphere, but there is a changing region around the middle of the sphere radius, in which coincidence is found between the distributions both in the model-type gland and in such a section. In practice the location of this places is often not known precisely enough and therefore much more accurate results are obtained in an acceptable processing time by measurements of a few slides with approximately equal distances.
