研究目的: |
1.探究无心电门控(ECG-less)技术结合指脉仪心率监测,再配合个性化曝光时相窗口的设置,能否在冠状动脉 CT 血管成像(CCTA)中降低辐射剂量,同时保证收缩期与舒张期图像的同步采集。 2.研究在个性化曝光时相窗口下,80 千伏峰值管电压(80 kVp)联合深度学习图像重建技术(DLIR),在进一步降低辐射剂量与对比剂用量方面的应用潜力。 |

|
Objectives of Study: |
The research objectives of this article are: To explore whether the combination of ECG-less technology and heart rate measurement via a finger pulse oximeter, along with the setting of personalized exposure phase windows, can reduce the radiation dose in coronary CTA imaging while ensuring the simultaneous acquisition of systolic and diastolic phase images. To investigate the potential of 80 kVp combined with deep learning image reconstruction technology (DLIR) in personalized exposure phase windows for further reducing the radiation dose and contrast agent dosage. |
