Abstract
A computerized approach to the problem of skeletal maturity is presented. The analysis of a computed radiography (CR) hand image results in obtaining features, that can be used to assess the skeletal age of pediatric patients. It is performed on a standard left hand radiograph. First, epiphyseal regions of interest (EROI) are located. Then, within each EROI the distals, middles, and proximals are separated. This serves as a basis to locate the extremities of epiphyses and metaphyses. Next, the diameters of epiphyses and metaphyses are calculated. Finally, an epiphyseal diameter and metaphyseal diameter ratio is calculated. A pilot study indicated that these features are sensitive to the changes of the anatomical structure of a growing hand and can be used in the skeletal age assessment.
