In-room radiography is not a new concept for image-guided radiation therapy. Rapid advances in technology, however, have made this positioning method convenient, and thus radiograph-based positioning has propagated widely. The paradigms for quality assurance of radiograph-based positioning include imager performance, systems integration, infrastructure, procedure documentation and testing, and support for positioning strategy implementation.
室内放射照相术对于图像引导放射治疗来说并不是一个新概念。然而,技术的快速发展使这种定位方法变得便捷,因此基于射线照片的定位已广泛传播。基于射线照片定位的质量保证范例包括成像器性能、系统集成、基础设施、程序文档和测试,以及对定位策略实施的支持。
