Quality control (QC) of X-ray equipment is an important task for patient safety. Periodic QC should not take long to perform, especially in a stressful clinical environment where downtime should be minimised. DOSESTAT-QC® is a new quick QC software with automatic image analysis that has been developed into a quality-assured and user-friendly tool for daily use. Trained X-ray personnel can easily perform the QC with selected image phantoms and immediately approve the results onsite before the equipment is used clinically. Image analysis includes visibility of contrast detail groups, homogeneity, signal-to-noise ratio and contrast-to-noise ratio. In the event of unapproved QC, a message is automatically sent to medical physicists and/or medical engineers. The results are stored over time and are available for trend analysis. The present paper describes the DOSESTAT-QC® software and its application in QC of interventional X-ray systems and mammography systems.
X 射线设备的质量控制（QC）是保障患者安全的重要任务。定期进行 QC 不应花费太长时间，尤其是在压力大的临床环境中，应尽量减少停机时间。DOSESTAT-QC® 是一款新的快速 QC 软件，具有自动图像分析功能，已开发成为一种质量保证且用户友好的日常使用工具。经过培训的 X 射线人员可以使用选定的图像体模轻松执行 QC，并在设备临床使用前在现场立即批准结果。图像分析包括对比度细节组的可视性、均匀性、信噪比和对比噪声比。如果 QC 未获批准，将自动向医学物理学家和/或医学工程师发送消息。结果会随时间存储，可用于趋势分析。本文介绍了 DOSESTAT-QC® 软件及其在介入 X 射线系统和乳腺 X 射线系统 QC 中的应用。
