摘要
双源CT具有双球管和双组探测器,其单扇区重建时间分辨率可达83m s,可在不控制心率的情况下获得高质量的冠状动脉血管图像。同时,双球管可同时输出不同能量的X线,提高了CT对不同组织的鉴别能力,拓展了CT的应用范围,提高了对病变诊断的正确性。
The dual source computed tomography is equipped with two X-ray tubes and two corresponding detectors. With its 83 ms-temporal resolution of single segment reconstruction, high quality coronary artery CT angiography can be acquired without heart rate control. Dual energy output by two X-ray tubes improves the differentiation of body tissues, clinical application and lesion diagnostic accuracy of CT.
