| Objective:Adobe Photoshop software by computer image analysis,freckles before and after treatment to calculate its image pixel color value percentage of change so as to arrive at intense pulsed light treatment of facial freckles in the cure rate,access to a more scientific and objective method of assessing the efficacy.Methods:Since October 2008 to April 2009 visit to Shanxi Medical University First Hospital out-patient clinics of plastic surgery patients with facial freckles,selected in accordance with the conditions of 30 eligible patients,before treatment at a constant light intensity freckle parts under the camera,according to patient's skin type to determine the laser energy density,using Israel's Flying Dayton One intense pulsed light therapy instrument for treatment.And asked patient in the first 3 weeks,6 weeks,9 weeks after the first treatment follow-up,each time before treatment to a constant light intensity in the same position under the camera,and then carry out treatment and after treatment in each 3 week taking pictures again,and finally all the pictures with Adobe Photoshop software to deal with partial uptake freckles images,will be obtained through the Adobe Photoshop image analysis software,one by one,access to then respective RGB values,to calculate the image pixel color value before and after treatment and the percentage of change,and then judge the effect of the treatment.Results:1.different skin types need a different laser pulse width and energy density treatment.2.using Adobe Photoshop image analysis showed freckles:The intense pulsed light treatment, 30 patients with facial freckle cure rate was 53.3%,efficiency was 96.7%.3.the treatment effect of the disruption to a significant impact on performance as follows:With the course of the increase in the rate of increase gradually faded,faded freckles obvious;but after a certain course of treatment,as the increase in treatment,although the regression rate of increase,but no significant difference,suggesting that the increased efficacy of treatment with no apparent significance.4.the use of digital technology on the computer to determine the effect,than the direct visual observation by more scientific,objective and accurate.5.intense pulsed light treatment of facial freckles effective,safe,without rest,without hospitalization,the patient is easy to accept.Conclusion:1.Adobe Photoshop software acquisition and analysis system is to measure the color pigments of a change of the skin to try new methods and effective. 2.High-tech digital computer technology,before and after treatment of facial freckles in the determination and analysis of images could be more objective,scientific,quantitative evaluation of the disease have clinical efficacy. |
