摘要： There is provided a method for detecting Ground Glass Opacity (GGO) using chest computed tomography. The method includes detecting a candidate cell having a brightness value within a detection range by sequentially scanning a three-dimensional image of a pulmonary region, and designating the candidate cell as a seed cell when surrounding cells of the candidate cell have brightness values within the detection range; when a plurality of seed cells are obtained by the designating of the candidate cell as a seed cell, grouping adjacent seed cells to obtain one or more candidate zones; and detecting one or more zones, which have a greater size than a GGO detection size and including therein more than the detection reference number of seed cells, out of the one or more candidate zones, and setting the detected one or more zones as one or more GGO candidates.
