The introduction and extensive application of spectral shaping filters during fluoroscopic imaging procedures have decreased the patient skin entrance exposures (air kerma) dramatically while the image quality is optimized and maintained. The purpose of this article is to demonstrate and understand the functionality and operation of fluoroscopic automatic dose rate control logic installed on a modern cardiovascular angiography system, as seen from the equipment operation point of view. The fluoroscopic "patient" entrance exposure (air kerma) rate and the flat panel image receptor input exposure (air kerma) rate were obtained for reference and future application.
在透视成像过程中，光谱整形滤波器的引入和广泛应用显著降低了患者皮肤入口处的照射量（空气比释动能），同时优化并维持了图像质量。本文旨在从设备操作的角度展示并理解安装在现代心血管血管造影系统上的透视自动剂量率控制逻辑的功能和操作。获取了透视“患者”入口处照射量（空气比释动能）率和平板图像接收器输入照射量（空气比释动能）率，以供参考和未来应用。
