Abstract:
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. Conclusions 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.
