- An Automatic Approach for Bone Tumor Detection from Non-Standard CT Images Catai Reis Hatice Bulent Bayram Ingeniería CT 3D region bone tumor growing algorithm Image processing techniques are applied in many fields of science. This study aims to detect tumors in the foot and create 3D models via computed tomography (CT), as well as to produce biometric data. 1 039 CT images were obtained from a server. The parameters used were a collimation of 64 detectors, a scanning thickness of 0,5-3 mm, and a pixel size of 512 x 512, with a radiometric resolution of the 16-bit gray levels. Noise reduction, segmentation, and morphological analysis were performed on CT scans to detect bone tumors. In addition, this study used digital image processing techniques to create a virtual three-dimensional (3D) model of bone tumors. The performance of our proposal was evaluated by analyzing the receptor operating characteristics (ROC). According to the results, the sensitivity, specificity, and precision in tumor detection were 0,96, 1, and 0,98%, respectively, with a 0,99% average F-measure. Radiologist reports were used for the sake of comparison. The proposed technique for detecting bone tumors of the foot via CT can help radiologists with its increased precision, sensitivity, specificity, and F-measure. This method could improve the diagnosis of foot and ankle tumors by allowing for the multidirectional quantification of abnormalities. 2023 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64379917012 https://www.redalyc.org/journal/643/64379917012/ https://www.redalyc.org/journal/643/64379917012/html/ https://www.redalyc.org/journal/643/64379917012/64379917012.epub https://www.redalyc.org/journal/643/64379917012/movil 10.15446/ing.investig.90748 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.3 Vol.43
