报告摘要
上个世纪40年代,美国科学家J.G Lynn首次提出将体外发射的超声波聚焦到体内对肿瘤进行手术治疗的设想。随后英、美、日、法、德、以等国也纷纷投入大量人力物力到该领域的研究。

在中国,从上世纪80年代开始,重庆医科大学联合南京大学、上海交通大学、中国科学院声学研究所、西安交通大学等单位潜心于聚焦超声外科技术的生物医学工程理论与临床相结合的研究。科研团队用实验科学的方法,从数千吨离体牛肝实验,再发展到小鼠、兔、香猪到恒河猴等动物实验,完成了上万例动物实验,对超声在组织内聚焦规律及剂量学等关键问题进行了深入研究,首次提出“生物学焦域”(Biological Focal Region,BFR)概念,以及生物学焦域与超声在理想声场中的声学焦域(Acoutic Focal Region,AFR)的对比定量研究。通过对生物学效应、治疗剂量学、组织声环境以及改变组织声环境等的研究,初步建立了聚焦超声外科的基础理论体系。

以此为基础,相继开发出了聚焦超声外科的设备,形成了临床方案,培养了世界上首批聚焦超声外科的专科医生,并在全球率先推向临床应用。全世界第一例聚焦超声保肢治疗骨肿瘤、保乳治疗乳腺癌、保肝治疗肝癌、保子宫治疗子宫肌瘤等均诞生在中国,患者至今生存长达15年以上。迄今为止,超声治疗系列化设备已在全球2000余家医院安装使用,累计治疗肿瘤及非肿瘤患者200余万例。

王智彪,医学博士,妇产科主任医师,重庆医科大学生物医学工程学院教授、博士生导师,超声医疗国家工程研究中心主任,中国生物医学工程学会副理事长。国家杰出青年基金获得者,973项目及自然基金委重大科研仪器设备研制专项首席科学家。主要研究方向:超声治疗学、妇产科学。多年来致力于妇科常见疾病子宫肌瘤、子宫腺肌病、宫颈炎症相关疾病以及外阴白色病变的微无创治疗。始终以“治疗——让病人受伤害更小”为从医理念。自1988年起,带领多学科专家团队研制出具有我国完全自主知识产权的大型治疗设备——“高强度聚焦超声肿瘤治疗系统”及CZF型超声波妇科治疗仪等,实现了“体外对体内疾病治疗”的医学梦想。2000年获得国家技术发明二等奖;2008年获得何梁何利基金“科学与技术进步奖”;2010年获得国家科技进步二等奖。

 

Geometric tools for biomedical image analysis - 清华大学生物医学工程系

报告摘要
While medical imaging has afforded a vast and quickly growing amount of spatial data, there is still a significant gap between "image'' and "knowledge''. In my work I explored the use of geometric tools and algorithms to help doctors and medical researchers make better sense of their images. In this talk, I will present two such examples. I will show how geometric skeletons are used to understand 3D biological shapes, from proteins to aneurysms, and how deformable atlases allow comparative analysis of 2D and 3D anatomic images.


Tao Ju is an Associate Professor in the Department of Computer Science and Engineering at the Washington University in St. Louis. He is the Ambassador for MISA to Tsinghua University. He graduated from Tsinghua in 2000 with a Bachelor Degree majoring in English and minoring in Computer Science, and he obtained his M.S. and PhD degrees in Computer Science from Rice University in 2005. He conducts research in computer graphics and bio-medical applications. He has served on the program committees of top-tier conferences including ACM Siggraph and Eurographics, and is currently an associate editor of journals IEEE Transactions on Visualization and Computer Graphics, Computer-Aided Design and Graphical Models. He has received a number of grant awards from NSF and NIH, including an NSF CAREER award in 2009.

 

After the talk, a quick introduction about Dept. of Biomedical Engineering of Washington University and research work, together with an introduction of Washington University in St. Louis and its McDonnell International Scholars Program, will be shared by Drs.  Yan LIU and Jiayu LI, respectively.
