科学领域:

  • 医疗成像医学成像
  • 手术导航 手术导航
  • 计算机辅助手术 计算机辅助手术

背景情况:

  • 增强现实 (AR) 通过记录手术前数据与实时腹腔镜视图来增强腹腔镜肝切除 (LLR) 中的手术内瘤定位.
  • 当前的AR系统将手术前的瘤模型直接投射到腹腔镜图像上,这可能会导致外科医生误导,因为仪器和腹腔镜的入口点不同.

研究的目的:

  • 通过开发一个钥匙洞意识可视化管道来解决AR引导LLR中的误导问题.
  • 精确估计和可视化工具的钥匙孔位置在腹腔镜坐标,以改善AR指导.

主要方法:

  • 开发了一种新的钥匙孔感知管道,通过观察手术工具来估计工具的钥匙孔位置.
  • 该系统将瘤从内部位置投射到肝脏表面,向工具的钥匙孔,然后向摄像头.
  • 实施了对瘤的钥匙洞感知可视化.

主要成果:

  • 对in silico和肝脏幻影模型的定量评估证明了管道的有效性.
  • 使用三个患者数据集进行的定性评估证实了钥匙洞意识方法的好处.
  • 提出的方法成功地解决了工具钥匙孔位置估计问题.

结论:

  • 开发的钥匙洞感知AR管道显著提高了LLR中手术内瘤定位的准确性.
  • 这种方法减轻了外科医生的误导,增强了对LLR中深层瘤的AR的实用性.
  • 该系统为AR引导的微创性肝脏手术提供了有希望的进步.
