SCH: EXP: Connecting surgical training software solutions on portable clients to interactive dynamics engines on the cloud

整形外科的实践是建立在科学和艺术的双重基础上的。在规划创伤性或先天性畸形的重建程序时，外科医生需要考虑美学，解剖功能和术后健康作为决定因素。整形外科医生可以使用的最重要的工具是使用拓扑结构改变作为医疗补救措施;事实上，大多数不平凡的修复都被设计为切割，切除，组织旋转和转位的复杂序列。掌握这种复杂的手术操作编排往往是一个有成就的外科医生和一个经验有限的外科住院医生之间最显着的特点。任何机会，外科医生在培训可以利用发展这种认知技能远离手术室有很大的价值，在减少错误的发生率，尽量减少术后并发症和提高生活质量的病人。今天，现代多处理器系统的计算能力表明，计算机模拟在这种训练中的帮助的可能性很大。此外，代表视觉计算社区对我们物理世界虚拟组件的功能建模和仿真的既得利益提供了丰富的数值和算法技术，可以利用这些技术实现这一目标。然而，特别是对于整形外科来说，在整形外科医生的认知训练变得像虚拟飞行模拟器上的飞行员训练那样计算机化之前，仍然存在一些挑战：数学，计算机工程和临床科学的贡献社区需要开发一种密切合作和沟通的机制，并且这种合作开发的成果必须能够被广泛的临床医生所使用，而不是被隔离的研究小组使用外来计算资源的情况所使用。这个跨学科的项目旨在生成一个可扩展的，易于部署的虚拟整形手术模拟测试平台，旨在促进计算机科学家和临床医生之间的密切合作，并为培训整形外科医生提供基础。该项目的活动将联合收割机的优势与便携式前端客户端的易用性结合起来，前者具有专门的、具有成本效益的并行计算平台，后者如平板电脑和移动的平台，可部署在私人诊所或教学医院的培训设施中。（一）申请人定义和构建算法技术和系统组件的流水线，通过该流水线，解决方案将作为网络服务交付给轻量级客户端平台，（ii）完善非线性组织的分析支配定律，并在基于虚拟计算机的模拟中利用它们，以非侵入性方式评估手术设计的可行性，并提供对手术结果的初步预测，（iii）简化建模假设，并通过对外科住院医师和经验丰富的专家的实际用户组进行颅面修复的认知训练器的试验部署来提高对实际算法需求的理解，（iv）提供计算动力学作为连续介质力学应用的云服务的交付蓝图，通过调查网络延迟和带宽限制的作用，并开发算法补救措施，以平衡软件解决方案的需求，从而促进远程交付。这一活动的预期产品将为面向卫生的教学机构的课程提供额外的好处，使学生在学习的早期阶段能够方便和廉价地使用虚拟模拟器，而不要求专门使用或在当地部署专门的并行计算资源。

The practice of plastic surgery is built on a dual foundation of science and art. In planning reconstructive procedures for either trauma-induced or congenital deformities, the surgeon needs to consider aesthetics, anatomical function and post-operative health as deciding factors. The most important tool at the disposal of a plastic surgeon is the use of topology change as a medical remedy; in fact, most nontrivial repairs are designed as elaborate sequences of cutting, suturing, tissue rotation and transposition. Mastery of this intricate choreography of surgical manipulations is often the most distinguishing feature between an accomplished surgeon and a surgical resident with limited experience. Any opportunities that a surgeon in-training can leverage to develop this cognitive skill away from the operating room have great value in reducing the incidence of errors, minimizing post-operative complications and improving the quality-of-life for patients. Today, the computational capacity of modern multiprocessor systems suggests the strong possibility of computer simulation aiding in this training exercise. In addition, the vested interest on behalf of the visual computing community on functional modeling and simulation of virtual components of our physical world provides a wealth of numerical and algorithmic techniques that can be leveraged towards this goal. However, especially for plastic surgery, a number of challenges remain before cognitive training of plastic surgeons would become as computerized as pilot training on virtual flight simulators: the contributing communities of mathematics, computer engineering and clinical science need to develop a mechanism of intimate collaboration and communication, and the fruit of such collaborative development must become accessible to a broad base of clinicians as opposed to instances of segregated research groups with access to exotic computing resources. This interdisciplinary project seeks to generate an extensible, easy-to-deploy testbed of virtual plastic surgery simulation, tailored to facilitate intimate collaboration between computer scientists and clinical practitioners and provide a foundation for training plastic surgeons in delicate cognitive skills. The activities in this project combine the benefits of specialized, cost-effective parallel computing platforms with the ease of use of lightweight front-end clients, like tablets and mobile platforms, that can be deployed in private practices or training facilities of teaching hospitals.The main objectives of this project are: (i) Defining and constructing a pipeline of algorithmic techniques and system components through which the capability of simulating the mechanics of deformable biological tissues at high resolution will be delivered as a network service to lightweight client platforms, (ii) Refining the analytic governing laws of nonlinear tissue, and leveraging them in a virtual computer-based simulation to assess, in a non-invasive manner, the viability of surgical designs and provide preliminary predictions for the outcome of procedures, (iii) Validate modeling assumptions, and improve the understanding of practical algorithmic needs by performing trial deployments of cognitive trainers for craniofacial repairs on actual users groups of surgical residents and seasoned experts, (iv) Provide a blueprint for delivery of computational dynamics as a cloud service for continuum mechanics applications, by investigating the role of network latency and bandwidth limitations and developing algorithmic remedies for balancing the needs of the software solution to facilitate remote delivery. The projected products of this activity will provide additional benefits to the curriculum of teaching health-oriented institutions, by providing easy and inexpensive access to virtual simulators for students in their early phases of study, without mandating exclusive use or local deployment of specialized parallel computing resources.
