摘要

This study presents an improved point-spread-function (PSF) mapping-based distortion correction method and accelerated PSF acquisition for distortion correction in EPI without loss of quality or reliability compared to full encoding.

机译：这项研究提出了一种改进的基于点扩展函数（PSF）映射的失真校正方法，并提供了加速的PSF采集，用于EPI中的失真校正，与完整编码相比，不会损失质量或可靠性。
