摘要
以NEMA NU2-2001《Performance Measurements of Positron Emission Tomography》标准推荐的方法对PET/CT设备性能进行验收测试;给出空间分辨率,散射分数,计数丢失和随机符合测量,计数丢失和随机符合校正,灵敏度,图像质量、衰减和散射校准准确性检测数据,从测试图像分析3D采集的性能优于2D采集,且图像质量好。
According to the NEMA NU2-2001《Performance Measurements of Positron Emission Tomography》to measure the performance of PET/CT, report the results including spatial resolution, scatter fraction, count losses, and randoms measurement, accuracy： corrections for count losses and randoms, sensitivity, image quality, accuracy of attenuation and scatter corrections. The image quality by using 3D acquisitions mode is better than that by using 2D acquisitions mode.
