Detect GGO Nodule Based on Dot Filter

Detect GGO Nodule Based on Dot Filter

Aiming at solving the problem that the dot-filter can not detect ground-glass-opacity nodules, a method based on an adaptive nonlinear filter and dot filter was used to detect them. Experiments were performed at 23 scans of CT images (containing 32 GGO nodule). The sensitivity of the detection metho...

Zusammenfassung:Aiming at solving the problem that the dot-filter can not detect ground-glass-opacity nodules, a method based on an adaptive nonlinear filter and dot filter was used to detect them. Experiments were performed at 23 scans of CT images (containing 32 GGO nodule). The sensitivity of the detection method was 84.4%. The time cost was 1.2 minutes per scan. This new method is superior to existing methods on the required time and sensitivity.
