近年来，在医学领域，手术模拟器与虚拟现实技术有望提供一个新的手段，以支持外科前线。我们已经开发了一个模拟脑外科手术使用的动态变形模型。识别靶组织的物理特性需要用到包括动态形变模型在内的大多数物理模型。在本研究中，我们确定了猪肝的物理性质。杨氏模量、泊松比和阻尼系数是模拟所必需的。以往对弹性模量的识别已有研究，但对泊松比和阻尼系数的识别研究较少。因此，在本研究中，我们进行拉伸实验来测量杨氏模量和泊松比，和振动实验来测量阻尼系数。
In recent medical field, surgical simulators with the technique of virtual reality are expected to provide a new means to support the surgical front. We have developed a simulation for brain surgery using a dynamic deformation model. Most of physics models, including the dynamic deformation model, are required to identify the physical properties of target tissues. In this research, we identified physical properties of swine liver. Young's Modulus, Poisson's Ratio and damping coefficient is necessary for the simulation. There are previous researches about identification of Young's Modulus, but that about identification of Poisson's Ratio and damping coefficient are few. Therefore, in this research, we conduct tension experiments to measure Young's Modulus and Poisson's Ratio, and vibration experiments to measure damping coefficient.
