Advances in imaging technology have facilitated the development of increasingly complex interventional cardiac equipment. Consequently, there is a need for definitive equipment requirements. The aim of the study is to assess the performances of different cardiac angiographic systems. A questionnaire was sent to centres participating in SENTINEL Project to collect dosimetry data (typical entrance dose rate in fluoroscopy and imaging mode), image quality evaluations (low and high contrast resolutions) and KAP calibration factors. Results from this survey could contribute to the explanation of patient dose variability in angiographic cardiac procedures and to derive reference levels for cardiac angiographic equipment performance parameters.
成像技术的进步推动了日益复杂的心脏介入设备的发展。因此，需要明确的设备要求。本研究的目的是评估不同心脏血管造影系统的性能。向参与SENTINEL项目的中心发送了一份问卷，以收集剂量测定数据（透视和成像模式下的典型入射剂量率）、图像质量评估（低对比度和高对比度分辨率）以及KAP校准因子。本次调查的结果有助于解释心脏血管造影手术中患者剂量的变异性，并得出心脏血管造影设备性能参数的参考水平。
