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. 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. The designed ray-based phase correction software can be used as a lightweight toolkit to compensate aberrated phase within clinical environment.

用于经颅聚焦超声的开源相位校正工具包。


经颅聚焦超声的相位校正对于调节由颅骨畸变引起的不必要的焦点偏移至关重要。当前研究的目的是设计和研究用于经颅聚焦超声的基于射线的相位校正工具包的可行性。使用所提出的相位校正工具包，焦点区域的峰值压力分别在目标 I 上提高了 140.5 ± 7.0%，在目标 II 上提高了 134.8 ± 19.1%。每次超声处理的总计算时间为 402.1 ± 24.5 毫秒。设计的基于射线的相位校正软件可以用作轻量级工具包来补偿临床环境中的相位差。
