Research progress on Clarity system in external beam radiation therapy of prostate cancer / 中华放射肿瘤学杂志

External beam radiation therapy (EBRT) is one of the main treatments for prostate cancer, and image-guided implementation of EBRT is more suitable for accurate radiotherapy. As a new type of image-guided technology, the Clarity system has been applied in the real-time tracking during EBRT for prostate cancer in clinical practice. While improving the accuracy of EBRT targeting, it also significantly reduces the side effects of traditional EBRT. In this article, the application of Clarity system in EBRT of prostate cancer and its existing problems were systematically elucidated.
