Abstract

In this article, a new method of information extraction on the basis of the differentiation of T₁- and T₂-weighted MR images is proposed. It relies on a technique of superposition of T₁- and T₂-weighted MR images with use of statistical dominance algorithm. On the basis of implemented image analysis, a reproducible extraction of growth zone of adolescent boys' wrists is possible.

Keywords: bone age; children; magnetic resonance; statistical dominance algorithm.
