A COMPUTER-SYSTEM FOR SKELETAL GROWTH MEASUREMENT

In this paper, we have presented a new image-processing system for the measurement of skeletal growth in pediatric radiology. From a standar d posterior and anterior view radiograph, taken from a left hand, the proposed system first automatically locates the phalangeal region of i nterest, and then measures the geometrical parameters associated with skeletal maturity. Finally, the bone age is estimated by using the sta ndard phalangeal length table. Clinical studies reveal that the comput er processing has resulted in an objective and accurate assessment of skeletal age. It greatly improves the shortcomings, including inter- a nd intraobserver variations and inaccuracy, reported in other research by manual methods. In conclusion, it is an inexpensive and useful too l for the evaluation of short-term abnormalities in the skeletal growt h of children. (C) 1994 Academic Press, Inc.
