  • “团结、专注、坚持”——iMed团队文化

    2020年初春,在全国新冠病毒疫情防控形式严峻的情况下,IMED团队虽然历经了很多前所未有的挑战,最后还是顺利通过了考验。大家在克服困难坚持科研工作的同时,合力完成了国自然和深圳市科创委两项新冠病毒防治项目的申报工作,每个人都功不可没。 继刘江老师年前提出“团结、专注、坚持”为主旨的IMED团队文化,并抛出用三棱镜色散原理实现具象表达的想法,刘慧颖老师第一时间展示了第一稿设计,并赢得了大家的一致赞扬。3月社会秩序陆续恢复常态,IMED团队文化即将定稿印刷。IMED深圳团队助理毕阿璇把第一稿设计整理成矢量图像后,又汇总了团队成员的意见,并结合了自己对团队文化的理解,经过两稿的修改之后,最终定稿。 IMED团队文化,以 “眼科影像”为团队研究核心,IMED所有成员为团队基础,“团结、专注、坚持”六个字为团队发展主旨。希望在2020年这个不平凡的年度,以全新的气息和姿态登场,照亮IMED更辉煌的远方。 作者:毕阿璇

  • 通用光学相干层析成像(OCT)和OCT血流造影(OCTA)图像噪声去除方法

    OCT是一种重要的眼科成像模态,具有非侵入式三维成像的特点,已经成为糖尿病视网膜病变、老年性黄斑病变等最常见眼底病的常规检测手段。OCTA是新兴的OCT功能成像,无需注射造影剂便可获得毛细血管形态、灌注以及血流动力学信息。近年来,OCTA已经被大量应用于眼科疾病的研究中,在检测灵敏度、准确性等方面具有显著优势,应用前景非常广阔。      然而,OCT图像中的散斑噪声与OCTA图像中的运动噪声,严重妨碍了眼底组织和血管结构的可视化,并导致难以进行定量分析。针对这一问题,已经大量的研究工作尝试去除OCT和OCTA图像中的噪声。但现有的研究都只针对其中一种有较好的效果。如下图所示,目前最为有效的OCT去噪算法BM4D和K-SVD对OCT图像效果较好,但分别会导致OCTA中毛细血管信息的丢失和模糊。     针对这一现状,近日,医学影像事业部(iMED中国团队)开发出一种能够通用于OCT和OCTA图像去噪的方法,并在两种类型图像的去噪中都取得了超越现有方法的成绩。该方法考虑到OCTA图像中的眼底血管在B扫描中与噪声形态接近,很容易与之混淆。因此提出在三维空间进行去噪,通过利用在en face平面上血管的线状结构特征与噪声相区分。该方法进一步利用到OCT和OCTA信号的稀疏性,采用三维剪切波(shearlet)进行特征变换和分解,并对噪声进行滤波,方法流程如下图所示。     由于剪切波相较于小波(wavelet)、曲线波(curvelet)等具有更强现状特征和边缘特征表示能力,该方法对于散斑噪声和运动噪声同时具有很强的消除能力。此外,由于该方法的无监督(unsupervised)特性,因此对于不同特征(正常、病灶)和不同来源的数据具有很好的鲁棒性和泛化能力。下图是针对一个老年性黄斑病变数据的OCT和OCTA去噪示例。     该项研究成果“Universal digital filtering for denoising volumetric retinal OCT and OCT angiography in 3D shearlet domain”已于2020年2月1日发表在领域权威期刊Optics Letters上(Opt. Lett. 45, 694-697 (2020)。   来自:

  • 不畏疫情,团结一致,顽强拼搏,打造一支敢想、敢做、勇于亮剑的新团队

    作者:王浩、岳星宇 2020年新年伊始,新冠病毒从武汉席卷全国,疫情变化时时刻刻都牵动着亿万中华儿女的心。每一位中国人都积极参与到了这场疫情防御的人民战争中去。在中国共产党的坚强领导下,我们必将战胜这场没有硝烟的战争。尽管现在疫情还没有结束,但是已接近尾声,各行各业陆续开工、开学。而iMED队员们也陆陆续续回到自己的工作岗位和学习状态。 iMED团队作为一个医学与人工智能交叉的一流研究团队,我们在iMED团队负责人刘江教授的带领下,用我们科研人员独有的方式投身于这场疫情阻击战中。回顾这一个多月,尽管疫情肆虐,我们响应国家号召,利用网络条件,实施远程调用服务器、网络办公和会议、远程课堂等方式,几乎每一位iMED团队成员都时刻对自己的科研和学业毫不松懈。最终交出了一副满意的答卷。 2019年中国农历的最后一天,万家灯火,喜气洋洋,大家都沉浸在新年的喜悦气氛中。就在此时,一场可怕的瘟疫正悄然席卷中华大地。中国基金委认识到这一突发情况,迅速布置了相关领域的科研专项布局。我们iMED团队拥有多年眼科人工智能分析的经验,同国内著名眼科医生一起,第一时间意识到,冠状病毒有可能是通过眼睛传播,同时会对眼部结构功能影像学产生影响。接下来的有关报道也进一步验证了这一观点。于是我们迅速布局,开展了相关项目申请工作。我们邀请了深圳市唯一一家新冠肺炎收治单位,深圳市第三人民医院即南科大第二附属医院,一同参与到此项目中去。深圳市第三人民医院拥有深厚的病毒研究经验,近5年来,医院先后承担国家重大科技专项25项,国家、省自然科学基金36项,累计获得科研经费超过4亿元。发表论文380余篇,包括国际顶尖杂志《N Engl J Med.》、《Science》、《Nature》、《Lancet》等。从项目策划,到项目书撰写,到各种材料的收集,我们有条不紊的进行。短短的几天时间,在iMED全体成员的积极努力和配合下,我们顺利完成了整个项目书和相关附件材料,第一时间提交给了中国基金委。值得一提的是,我们是南科大仅有的四个申报病毒专项的团队之一,并且得到了中国科学院院士陈十一校长的大力赞扬。此次项目申请,充分证明了我们iMED是一个敢想、敢做、勇于创新和亮剑的团队。 同时,深圳市基金委也紧急发起了新冠病毒专项。病毒具有潜伏期长、传播快、致死率高的特点,严重影响人类的生命健康。因此通过便捷有效方式,对易感人群实现远程早期筛查是控制和治疗此次肺炎疫情关键。据传染学专家指出,该病毒感染后,其首发症状在眼部。研究表明冠状病毒感染后可发生从轻度到重度的眼部疾病。通过便捷智能手机和眼科设备拍摄的眼部图像进行智能算法自动分析,是潜在实现该病毒筛查和早期诊断的重要途径,为患者争取关键干预和治疗时间。我们意识到做好通过眼科感染的新冠病毒精准筛查,不仅仅需要眼科图像信息,而且还需要基因信息。于是,我们乘胜追击,联合深圳市第三人民医院、深圳市华大生命研究院和深圳市人民医院眼科一同申报了此次专项。深圳市华大生命研究院致力于生命科学、生物技术和医疗应用领域的多组学研发的非营利机构,在新一代测序技术平台的基因检测产品开发和遗传病致病基因发现及机制研究具有卓越的成绩。深圳市人民医院眼科科室拥有世界一流的眼科设备和眼科诊疗技术。该项在iMED全体成员的积极推动下,已经基本完成项目申报工作。 iMED团队是一个专注于眼科人工智能分析的一流团队,在疫情期间,团队重新确立了“团结、专注、坚持”的团队精神和象征这一精神的logo。同时,团队也重新调整了战略部署、管理架构和团队核心方向。团队确定了以刘江教授为首的管理委员会。在明确了赵一天对于iMED宁波的领导基础上,团队也重新确立了五大研究方向:以赵一天为首的“眼脑联动”方向、以杨建龙为首的眼科智能硬件方向、以胡衍为首的手术导航团队、以RISA为首的眼前节分析团队和以方建生为首的工程团队。他们各司其职,分别领导着包括工程师、博士生、硕士生、本科生在内的十余人的小团队。 在抗击疫情的岁月里,我们iMED团队传承相互关爱的优良传统,发生了许多令人感动的故事。与我们拥有多年合作关系的日本TOMEY集团的RISA博士为我们从日本寄来了100副外科口罩;阿璇为了保障项目申报的顺利进行大年初四从老家安徽赶回了深圳;胡衍加班加点通宵写项目申请书;愿愿冒着被感染的风险去材料所盖章。这一幕幕都戳动了我们的心房,我们为她们点赞和喝彩。 秉承着停课不停学的教育部指示,刘江教授积极备课,通过网络为本科生上《多媒体分析》的课程;赵一天申报了2020年度国际伙伴计划对外合作重点项目;杨燕鹤解决了C-SCAN和B-SCAN的显示问题;星宇和姗姗制定了iMED防疫准则;方建生、胡衍和章晓庆都分别提交了相应的专利和论文等等,还有很多很多,每个iMED成员都做出了自己的贡献。 如果说每个人是一滴水,那我们团队就是一条河。我们只有借助团队的力量、发挥自己的优势,才能惊涛拍浪,撑起万吨巨轮,一路高歌奔向大海。疫情再深,没有我们相互关心的温情深;疫情再高,没有我们团结一致的齐心高;疫情再猛,没有我们顽强拼搏的精神猛。不畏疫情,团结一致,顽强拼搏,打造一支敢想、敢做、勇于亮剑的新团队。 2020年2月23日 于深圳集悦城
