Abstract: Objective To explore the potential and feasibility of portable 3D scanner in quantitative assessment of scar in clinic. Methods From April 2015 to November 2015, 10 patients were randomly selected for scar scanning with portable3 D scanner of high resolution. The scanned data were analyzed with specific software for scar quantitative characterization.Correlation and Difference between scanned data and manually measured data were also analyzed. Results The scanned data were significantly correlated with the manually measured data, and the difference was also significant（P 0.05）.Conclusion The portable 3D scanner with high solution can reliably reveal scar characters via 3D image reconstruction and quantitative analysis, and therefore is possible to become an effective tool for objective and quantitative analysis, and to be applied for scar diagnosis and assessment of clinical therapy.
