肿瘤超声引导下的放疗研究现状

Research status of ultrasound-guided radiotherapy for tumors

在肿瘤放疗中,图像引导技术对于提高放疗精确程度至关重要。超声图像由于具有实时性、可重复性、无辐射等优点,已逐渐应用于临床放疗的摆位验证及自适应治疗中。本文就超声图像引导技术在放疗中的应用进行归类与分析,并介绍其最新进展。

Image-guided techniques are critical to improving the accuracy of radiotherapy for tumors.Ultrasound images have been gradually applied in the set-up verification of clinical radiotherapy and adaptive radiotherapy because of the real-time,reproducible and non-radiative characteristics.In this paper,the application of ultrasound image-guided technology in radiotherapy was classified and analyzed,and the latest research progress was introduced.
