Deformable anatomical models for image guidance and simulation of medical procedures

申请人和他的团队的研究是在生物医学工程领域，涉及获得包括组织变形的解剖模型的方法，以及基于这些模型指导和模拟医疗程序的方法，包括机器人辅助程序。我们将考虑基于针头的手术和机器人辅助的微创手术。研究领域包括组织变形或应变的成像，以及由应变产生的组织粘弹性特性的成像，称为弹性成像。弹性成像涉及外部组织激励的应用，例如对身体上的超声探头的压缩、对所产生的组织变形的估计、使用模型对变形进行建模以及使用该模型来计算组织机械特性的图像。

The applicant and his group's research is in the area of biomedical engineering, and is concerned with methods of obtaining anatomical models that include tissue deformation and methods of guiding and simulating medical procedures, including robot-assisted procedures, based on such models. We will consider needle-based procedures and robot-assisted minimally invasive surgery. The research area that involves the imaging of tissue deformation, or strain, and of tissue viscoelastic properties derived from strain, is called elastography. Elastography involves the application of an external tissue excitation, such as the compression of the ultrasound probe on the body, the estimation of the resulting tissue deformation, the modeling of the deformation using a model, and the use of the model to compute images of tissue mechanical properties.
