论文摘要
医疗干预措施的现实建模是开发高保真医学模拟器的关键要求。在这项工作中，已经开发了适用于针对针与组织的针相互作用的实时触觉反馈的参数化模型。基于Fe的数值模拟是在Abaqus/CAE和COMSOL中进行的，然后在MATLAB中进行后处理以开发参数模型。通过与各种文献结果进行比较验证的获得的参数模型。还开发了基于MATLAB的GUI应用程序，该应用程序利用这些结果并提供界面来检查所需的力是否已知的针头/方向。
The realistic modelling of medical interventions is the key requirement for development of high-fidelity medical simulators. In this work, a parameterized model suitable for real-time haptic feedback of needle interaction with tissue has been developed. The FE based numerical simulations are performed in ABAQUS/CAE and Comsol and then the results are post-processed in MATLAB to develop the parametric model. The obtained parametric model validated through comparison with various literature results. A MATLAB based GUI App has also been developed that utilizes these results and delivers an interface to examine the desired forces for any known needle position/orientation.
