tailieunhanh - Model of colposcopy using polarized light and effective early

In this study, we improved the traditional colposcopy with a polarized light source, and captured images with high resolution. Based on the image obtained, we developed image processing algorithms, initially analyzed and evaluated some of the common features of cervical disease. | 96 SCIENCE & TECHNOLOGY DEVELOPMENT, Vol 20, 2017 Model of colposcopy using polarized light and effective early Phan Ngoc Khuong Cat, Huynh Quang Linh, Nguyen Ngoc Quynh, Ly Cao Duong. Abstract — Cervical disease is one of the common diseases, it occurs in women and has a growing tendency. In particular, cervical cancer is one of the most common diseases. The disease can be cured if it is detected early and treated under the guidance of a physician. The usual cervical examination methods are biopsies, and colposcopy. Recently, many studies have applied imaging techniques in the analysis and evaluation of cervical pathology characteristics [1-3]. In this study, we improved the traditional colposcopy with a polarized light source, and captured images with high resolution. Based on the image obtained, we developed image processing algorithms, initially analyzed and evaluated some of the common features of cervical disease Index Terms— colposcopy, polarized 1. INTRODUCTION I n some reproductive health studies, the worldwide burden of cervical disease is enormous, with over 500 000 cases of cervical cancer diagnosed each year, resulting in 250,000 cases dead. The incidence of cervical disease is highest in developing countries and lowest in Western developed countries, where the screening program has significantly reduced the incidence of the disease [4]. In Vietnam, cervical cancer is the second most common gynecological cancer, after breast cancer. Each year, there are more than 5,000 new cases and more than 2,500 deaths caused by the disease.
