Abstract(in English) | We are investigating an automatic detection method for extravasation using contrast-enhanced CT images in order to reduce the burden on doctors in emergency medicine. In this paper, we propose a bone removal method based on the watershed algorithm for bone removal, which is one of the important factors in the detection process, and improve its performance. In addition, the number of false positive was reduced by using a random forest learner to classify candidate area using texture feature. By using the proposed bone removal method, the sensitivity was improved and the detectability was improved compared to the conventional method. In addition, false positives were reduced by about 35% compared to previous studies by classifying candidate regions corresponding to bone misdetection. |
