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.
背景
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。本研究的目的是设计并研究一种基于射线的经颅聚焦超声相位校正工具包的可行性。
结果
使用所提出的相位校正工具包，在目标I上，焦点区域的峰值压力分别提高了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。
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，在临床环境中补偿畸变相位。
