大脑 BRAIN
大脑是脊椎动物头骨中的一种软组织。它是高度异质性的,因为它包含白质和灰质,它们具有不同的力学行为。常用的脑组织测试方法有动态剪切、拉伸、压缩和压痕。可以用机械方法测试大脑的体积特性,也可以在单独的样本中进行脑组织的结构建模。需要对脑组织的机械特性有全面的了解,才能将组织的机械反应与实际损伤联系起来。此外,有关组织特性的准确信息将允许对脑组织模型进行有限元分析。对大脑进行机械测试,以了解其对损伤、手术和病理学的反应。此外,需要测量脑组织的机械特性,以帮助开发自动化手术工具、机器人和外科医生培训系统。
BRAIN
Brain is a soft tissue contained in the skull of vertebrates. It is highly heteregenous because it contains both white and gray matter, which have different mechanical behaviors. Commonly used test methods for brain tissue are dynamic shear, tension, compression and indentation. Brain can be mechanically tested for bulk properties or in separate samples for constitutive modeling of brain tissue. A complete knowledge of the mechanical properties of brain tissue is needed to relate the mechanical response of the tissue to actual damage. Also, accurate information about tissue properties will allow implementing finite element analysis of brain tissue models. Mechanical testing of brain is performed to learn about its reaction to injury, surgery and pathologies. Moreover, accurately measured mechanical properties of brain tissue are needed to aid in the development of automated surgical tools, robots and surgeon training systems.
