摘要
背景：经颅聚焦超声的相位校正对于调节颅骨像差引起的不必要的焦点偏移至关重要。本研究的目的是设计并调查基于射线的经颅聚焦超声相位校正工具包的可行性：结果：使用建议的相位校正工具包，目标 I 和目标 II 的焦点区峰值压力分别提高了 140.5 ± 7.0% 和 134.8 ± 19.1%。每次超声的总计算时间为 402.1 ± 24.5 毫秒：结论：所设计的基于射线的相位校正软件可作为一种轻量级工具包，用于在临床环境中补偿畸变相位。
An open-source phase correction toolkit for transcranial focused ultrasound.
Background: The phase correction on transcranial focused ultrasound is essential to regulate unwanted focal point shift caused by skull bone aberration. The aim of the current study was to design and investigate the feasibility of a ray-based phase correction toolkit for transcranial focused ultrasound.
Results: The peak pressure at focal area was improved by 140.5 ± 7.0% on target I and 134.8 ± 19.1% on target II using proposed phase correction toolkit, respectively. A total computation time of 402.1 ± 24.5 milliseconds was achieved for each sonication.
Conclusion: The designed ray-based phase correction software can be used as a lightweight toolkit to compensate aberrated phase within clinical environment.
