A Fully-Automated Algorithm Dedicated to Computing Metacarpophalangeal and Interphalangeal Joint Cavity Widths

In Europe, as well as in the United States of America, from 11\% to 14\% of residents suffer from rheumatoid arthritis. To give a diagnosis, an x-ray of patient's hand is taken, but regular analysis is exceedingly complicated, therefore it should be automated. It was not necessary to use a segmentation method. In order to find the joint cavity widths it was sufficient to use binarisation and thinning, and then analyze an obtained skeleton. The presented algorithm gives satisfactory results in the joint cavity width analysis (81% correct results).
