双能X射线计算机断层扫描（DECT）近年来获得了极大的关注。该技术提供了区分不同材料的潜力，因此提供了识别不同病理的可能性。在本文中，我们提出了一种双能量投影成像技术，利用侦察数据采集模式的CT结合快速kVp切换能力。体模实验表明，该方法在去除重叠结构和提高体内小结构的可视化方面具有优势。
Dual energy x-ray computed tomography (DECT) has gained a significant attention in recent years. The technology offers the potential to differentiate different materials, and therefore provides the possibility of identifying different pathologies. In this paper, we present a dual-energy projection imaging technique by utilizing the scout data acquisition mode of CT in conjunction with the fast-kVp switching capability. Phantom experiments have shown its advantage in removing overlapping structures and improves the visualization of small structure inside the body.
