摘要
随着电子病例技术的发展,牙科X光图片的数字化分析在牙科疾病的诊断治疗中越来越重要。该文讨论了一种适用于电子病例的牙科X光图像处理、测量系统。针对用户的感兴趣区域(ROI),实现放大镜功能,并调整感兴趣区域的亮度、对比度。运用种子填充算法对用户选取的封闭区域填充颜色,可以较为精确地测量封闭牙齿病变区域的面积。
With the developing of EPR, digital analysis of dentistical X-ray images is becoming more and more important in dentistical disease diagnosis and treatment. This paper proposes an EPR-suitable dentistical X-ray image processing and measuring system. The system provides a function of adjusting contrast and brightness of ROI, which is a special part selected by user from a dentistical X-ray image. It can also zoom in the ROI as a magnifier. Furthermore, a method using ＂flood-fill＂ function is proposed, which can measure the section area in a precise way.
