用于包括脑移位补偿的低成本术中图像引导神经导航器的框架
Framework for a low-cost intra-operative image-guided neuronavigator including brain shift compensation
摘要:
在本文中,我们提出了一种方法来解决问题的脑组织变形被称为“脑移位”。这种变形发生在整个神经外科干预过程中,并强烈改变了迄今为止在临床常规中使用的神经导航系统的准确性,这些系统仅依赖于术前患者成像来定位手术目标,例如肿瘤或功能区域。我们的术中图像引导系统的框架的一般描述后,我们描述了一个程序,以生成患者特定的有限元网格的大脑,并提出了一个生物力学模型,可以考虑组织变形和外科手术,修改大脑结构,如肿瘤或组织切除。
英文摘要:
In this paper we present a methodology to address the problem of brain tissue deformation referred to as 'brain-shift'. This deformation occurs throughout a neurosurgery intervention and strongly alters the accuracy of the neuronavigation systems used to date in clinical routine which rely solely on pre-operative patient imaging to locate the surgical target, such as a tumour or a functional area. After a general description of the framework of our intra-operative image-guided system, we describe a procedure to generate patient specific finite element meshes of the brain and propose a biomechanical model which can take into account tissue deformations and surgical procedures that modify the brain structure, like tumour or tissue resection.
