Robust techniques for automated Bone Age Assessment

Abstract

This paper focuses on the contribution of the various wrist bones in the different stages of growth and four techniques for Bone Age Assessment (BAA) process. Bone age is a reliable indicator of growth and skeletal BAA is used in the management and diagnosis of endocrine disorders. Bone age can be estimated from the left-hand wrist radiograph of the subject. The strength of the BAA procedure is greatly influenced by the quality of the features exploited and the contribution of the wrist bones employed. The four systems presented work according to the renowned Tanner and Whitehouse (TW2) method, based on the Region of Interest (ROI) taken from the wrist bones. The systems ensure accurate and robust BAA for the age range 0-10 years for both girls and boys.
