| Abstract(in English) | To aid radiologists in the diagnosis of pneumothorax from chest radiographs,we are developing an automated method for detection of subtle pneumothorax.The computerized method is based on the detection of a fine curved-line pattern,which is a unique feature of radiographic findings of pneumothorax.Initially,we determine regions of interest in each upper lung area,where subtle pneumothoraces commonly appear.The pneumothorax pattern is enhanced by Sobel filter.Rib edges included in this edge-enhanced image are removed,based on the locations of ribs that are determined separately.A subtle curved line due to pneumothorax is then detected by means of the Hough transform.The detected pneumothorax pattern is marked on the chest image.With our present computer method applied to 50 chest images(28 normals and 22 abnormals with pneumothorax),we were able to detect 77% of pneumothoraces,with 0.28 false-positives rate. |
