计算机辅助乳房整形与再造关键技术研究 Computer aided breast plastic surgery and reconstruction

项目摘要：据《中国肿瘤登记年报》，我国每年新发乳腺癌病例近21万，且以每年2%速度增长。患者单/双乳切除后对乳房再造需求巨大。此外我国对美胸手术的需求每年也有10多万例。本项目研究计算机辅助乳房再造的关键技术，具体包括图形图像多模态数据相结合确定乳房解剖学位置；乳丘分割与虚拟胸壁构建；基于图形图像多模态数据对乳房体积的进一步精准测量；乳丘形态三维特征提取与计算；基于患者个体特征参数与审美准则建立理想乳房三维模型；基于假体特征数据构造假体三维模型数据库。本项目在理论上将拓展计算机辅助乳房整形和再造研究，对乳房体积精准测量、乳房形态精确判断、隆胸假体正确选择、再造乳房形态预测、术后效果评估、手术规划以及虚拟展示等方面有重要意义。集成所研究关键技术得到一个计算机辅助乳房整形与再造原型系统，在浙江大学第一附属医院乳腺疾病诊治中心以及杭州整形医院进行实验性应用。本项目在医学整形领域属于国际前沿性研究，在国内有广泛应用前景。

注：笔者在2015年3月27-29日北京举行的第五届全国乳房整形美容大会上作了《计算机辅助乳房整形与再造技术现状与展望》的报告。在1160个参会人员中笔者是唯一一位搞计算机图形的研究人员。数字化诊疗设备即将以重点专项的形式作为‘十三五’首发的重点专项，欢迎有志数字化诊疗研究的学生参与本项目，为我国的数字化诊疗做出贡献。

Abstract:  According to Cancer Registry Annual Report, the number of new cases of breast cancer in China is estimated to reach approximately 210,000 per year, and this number would increase at an annual rate of 2%. As a result, patients with one breast or both breasts removed would desire breast reconstruction. Additionally, China has more than 100,000 women undergone breast plastic surgery each year. In this study we will investigate key technologies of computer aided breast plastic surgery and reconstruction, including determination of anatomy position of breasts by utilizing 3D graphics and X ray images, abstraction of features on 3D breast models, accurate estimation of breast volume by multi-module data, construction of ideal 3D breast model based on individual data on patient’s body, construction of implant model data set by utilizing the sizes and specifications of each breast implant type. This study would extend the research area in computer aided plastic surgery and reconstruction, and significantly benefit accurate pre surgical measurement of breasts, description of breast shapes, correct selection of implants, prediction of reconstructed breasts, breast surgery planning and virtual surgery, etc. We will produce a prototype for breast plastic surgery and reconstruction, and continually test and evaluate this prototype to optimize its utility in the clinic. This study is a hot research topic in breast plastic surgery and reconstruction, and the system produced has potential applications nationwide.
