颞骨扫描参数的优化与应用

Optimization and application of temporal bone scanning parameters

目的:优化颞骨扫描参数,提高图像质量,缩短扫描时间,减少患者的放射线照射。方法:使用西门子16排螺旋CT机,征得20位志愿者同意,采用默认参数和优化参数,在同一部位的相同范围扫描,采集容积数据。结果:20例志愿者的图像对比分析,优化参数17例优于默认参数,2例相同,1例差于默认参数。结论:经过对比实验和1000例优化参数的应用统计,优化参数图像质量高,扫描时间是默认参数的1/7,患者放射线量明显减少,优化参数优于默认参数,具有推广使用价值。

Objective To optimize the temporal bone scanning parameters, upgrade the picture quality, shorten the scanner time, and decrease the radiographic exposure during the scanning. Methods The scanning was performed on 20 volunteers using 16 spiral CT in the same position and range with optimizer parameters and general parameters respectively, and then the volume data were collected. Results Through comparision and analysis of the images of the 20 volunteers, 17 of them using the optimizer parameters were better than those using general ones, 2 of them showed no obvious difference, and 1 was not as good as the general one. Cone, ludons Through the experiment and the statistics of 1000 cases using optimizer parameters, the picture quality using optimizer parameters is better, the scanner time is 1/7 of the general scanning, and the radiographic exposure is decreased. Optimizer parameters are better than the general ones and worth popularizing.
