The RFA procedures rely on a precise positioning of the radiofrequency electrode and the complete destruction of the tumour. This article presents new optimization techniques to improve such surgical procedures.
A method to optimize the coverage of the tumour by successive RFA destructions and an in vitro procedure with simulated tumours have been developed.
The guidance system and optimization coverage have been tested on 3D simulation and by the surgeon in vitro on a heifer liver. In this context, the RFA electrode is optically tracked and guided.
The optimization method provides needle placements that ensure a complete theoretical ablation of the tumour, and the guidance system helps the surgeon to reach each position of destruction.
RFA 程序依赖于射频电极的精确定位和肿瘤的完全破坏。本文提出了新的优化技术来改进此类手术程序。
开发了一种通过连续 RFA 破坏来优化肿瘤覆盖范围的方法和一种具有模拟肿瘤的体外程序。
该引导系统和优化覆盖范围已在 3D 模拟和牛肝脏的体外由外科医生进行了测试。在这种情况下,RFA 电极是通过光学跟踪和引导的。
该优化方法提供了针放置位置,可确保肿瘤的完全理论消融,而引导系统则帮助外科医生到达每个破坏位置。
