Identifikasi Kerusakan Tulang Dengan. Analisis Citra Foto Sinar-X = Identification on Damage of Bones using Image Analysis of X ray Photos

The objective of this research was to prove that digital image analysis can assist practitioners to identify the damaged bones. The samples used were normal and damaged long bones, with kinds of bones were humerus, legs, and knees. Some image analysis techniques performed were image preprocessing until an image was prepared to be further processed, feature extraction, and image segmentation. Image preprocessing may be noise removal, intensity adjustment, or histogram equalization. In part of feature extraction, spatial feature extraction, and boundary extraction were used, whereas in part of segmentation, edge \u27detection and its dilation were used. The result were the followings : (a) the subjectivity level of identification on bones could be degraded using software developed(b) the conventional edge detection had a lack in identifying the interested bone image boundaries(c) the combination of histogram equalization and dilation of edges gives adequate information on identificationand (d) the software developed has an ability to assist practitioners to explore the informations of swelling of soft tissues, to identify the demaged bones or bone tumors, and for the purposes of enhancement or restoration on bone images Key words : edge detection, dilation, intensity adjusment, histogram equalizatio
