(57) Abstract For analyzing the merit of image of the lung small knot detection in digital chest radio graphic representing, being the computer storage which stores the instruction in order to run manner and the manner which are automated, in order to verify the candidate small knot which is while representing it treats image (1200); The interest section (ROI) which includes the candidate small knot inside ROI is established (1210); Image reinforcement of the candidate small knot inside ROI is executed (1220); After executing image reinforcement, the histogram of the edge gradient which was accumulated as function of emission direction angle inside ROI profit (1230); The step which decides (1240 whether or not it is positive was based on the histogram where you can obtain the candidate small knot and is wrong,) is included.
