US-Egypt Cooperative Research: Three-Dimensional Deformable Modeling of the Spine.

0001563 Abdel-Malek描述：该奖项旨在支持爱荷华州爱荷华州市爱荷华州大学机械工程助理教授Karim Abdel-Malek博士和埃及开罗美国大学副教授Ahmed Sameh Mohamed博士的合作项目。 他们计划利用现有的数据和医学图像开发一种新的脊柱手术模拟方法，包括建立脊柱运动的体积模型。 物理模型基于关节式身体的生物力学，其近似地将脊柱的形状以及与其运动相关联的力和扭矩联系起来。 一个实时计算的运动是可能的，由于处理的基本运动来自一个建议的铰接有限元法（AFEM）。 AFEM是一种综合的努力，以有效的方式（实时或接近实时）对组织和刚体运动进行建模，同时保持有限元方法固有的精度。 由此产生的可变形模型将使研究人员，外科医生和从业者能够更好地模拟手术干预，更好地可视化复杂的脊柱解剖结构，并且是实现虚拟现实力反馈（触觉）感觉的第一步。范围：美国研究者Abdel-Malek博士和埃及合作者Mohamed博士在本研究的具体方面拥有丰富的经验，即在变形体和刚体的力学中，以及在计算机技术中。 这一议题既重要又及时，预计将对美国和埃及有利。 爱荷华州大学的一名美国研究生有望参与这项研究，从而获得国际经验。 该提案符合INT的目标，即支持在共同感兴趣的领域进行合作研究。 该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。

0001563Abdel-MalekDescription: This award is to support a collaborative project by Dr. Karim Abdel-Malek, Assistant Professor of Mechanical Engineering, University of Iowa, Iowa City, Iowa, and Dr. Ahmed Sameh Mohamed, Associate Professor, American University of Cairo, Cairo, Egypt. They plan to utilize existing data and medical images to develop a new method for spinal surgery simulation, including building a volumetric model of spinal movements. The physical model is based on the biomechanics of articulated bodies that approximately links the shape of the spine and the forces and torques associated with its movements. A real-time computation of the motion is possible due to the processing of elementary movements derived from a proposed Articulated Finite Element Method (AFEM). AFEM is an integrated effort at modeling tissue and motion of rigid bodies in an efficient manner (at or near real-time) while maintaining the accuracy inherent in finite element methods. The resulting deformable model will enable researchers, surgeons, and practitioners to better simulate surgical interventions and better visualize intricate spine anatomy, and is a first step towards achieving virtual reality force-feedback (haptic) sensation.Scope: The US investigator, Dr. Abdel-Malek and the Egyptian collaborator, Dr. Mohamed have, extensive experience in the specific aspects of this research, namely in mechanics of deformable bodies and rigid bodies, and in computer techniques. The topic is important and timely and is expected to be of benefit to the US and Egypt. A US graduate student at the University of Iowa is expected to participate in the research, thus gaining international experience. This proposal meets the INT objective of supporting collaborative research in areas of mutual interest. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
