摘要
以肝脏CT数据为原始数据,创建肝脏模型,对虚拟手术中肝脏的变形和力反馈进行研究。采用质点-弹簧阻尼力反馈计算模型,实验过程中视觉刷新频率稳定维持在65Hz以上,触觉刷新频率稳定维持在1000Hz以上,较好地对虚拟手术过程中产生的形变和力反馈进行了模拟,有效地保证了实验的真实性和实时性。
Based on the liver CT data,the liver model was created and the liver deformation and force feedback during virtual surgery were studied.The particle-spring damping force feedback calculation model was adopted.During the experiment,the visual refresh frequency remained stable above 65 Hz and the tactile refresh rate remained above 1000 Hz.The deformation and force feedback during the virtual surgery were better simulated,the authenticity of the experiment and real-time were ensured effectively.
