本研究的目的是根据腹部CT中广泛使用的FBP和新近开发的SAFIRE等物理参数对图像进行客观的比较和分析，以确定最优的核函数。CT图像由一个直径为20 cm的充满水的圆柱体模型和Somtom Definition Edge CT(西门子医疗集团)采集。重建的图像具有3 mm厚的核，例如FBP，其具有B10(非常平滑)、B20(平滑)、B30(中等平滑)、B40(中等)、B50(中等锐化)和Safire，其具有i30(强度1到5)和i40(强度1到5)。在重建图像中使用图像J(版本1.49q；美国马里兰州贝塞斯达国立卫生研究院)测量SNR、PSNR、RMSE、MAE和PLOT Profile。结论：腹部CT的最佳核素应为Safire I30核强度为1。
This study is to determine an optimum kernel, which objectively compares and analyzes the image according to physical parameters such as FBP, which is widely used in abdominal CT, as well as SAFIRE, which was developed recently. CT images were acquired with a 20-cm-diameter cylinder phantom filled with water and a SOMATOM Definition Edge CT (Siemens Healthcare). The images were reconstructed with a 3-mm-thick kernel such as FBP, which has B10 (very smooth), B20 (smooth), B30 (medium smooth), B40 (medium), B50 (medium sharp), and SAFIRE, which has I30 (strength 1 to 5) and I40 (strength 1 to 5). SNR, PSNR, RMSE, MAE and Plot profile were measured using the image J (version 1.49q; National Institutes of Health, Bethesda, MD, USA) in reconstructed images. In conclusion, the optimum kernel for abdominal CT should be a SAFIRE I30 kernel of strength 1.
