External beam radiotherapy (EBRT) is one of the curative treatment options for prostate cancer patients. The aim of this treatment option is to irradiate tumor tissue, while sparing normal tissue as much as possible. Frequent imaging during the course of the treatment (image guided radiotherapy) allows for determination of the location and shape of the prostate (target) and of the organs at risk. This information is used to increase accuracy in radiation dose delivery resulting in better tumor control and lower toxicity. Ultrasound imaging is harmless for the patient, it is cost-effective, and it allows for real-time volumetric organ tracking. For these reasons, it is an ideal technique for image guidance during EBRT workflows. Review papers have been published in which the use of ultrasound imaging in EBRT workflows for different cancer sites (prostate, breast, etc.) was extensively covered. This new review paper aims at providing the readers with an update on the current status for prostate cancer ultrasound guided EBRT treatments.
体外束放射治疗（EBRT）是治疗前列腺癌患者的一种有治愈可能的选择。该治疗方法的目的是照射肿瘤组织，同时尽量保护正常组织。在治疗过程中频繁进行成像（图像引导放射治疗）可以确定前列腺（靶区）和危险器官的位置和形状。这些信息用于提高放射剂量传递的准确性，从而更好地控制肿瘤并降低毒性。超声成像是对患者无害的，具有成本效益，并且可以实时进行容积器官跟踪。因此，它是 EBRT 工作流程中图像引导的理想技术。已经发表了一些综述论文，广泛涵盖了不同癌症部位（前列腺、乳房等）的 EBRT 工作流程中使用超声成像的情况。这篇新的综述论文旨在为读者提供有关当前前列腺癌超声引导 EBRT 治疗现状的最新信息。
