Trials of pneumoconiosis screening using mobile CT

我们尝试改进自己研发的移动螺旋CT肺癌筛查系统，并尝试将该系统应用于尘肺的筛查。在螺旋CT筛查系统的改进方面，我们与NTT网络解决方案研究所的研究人员合作，完成了一套对比以往CT图像和无钥匙报告系统的CT评估系统。将CT图像数据转换为DICOM格式，与被检查人的一般信息数据一起存储在PC服务器中。当我们在显示当前CT图像的CRT上绘制以前的CT时，用日文写名字的排序方法是足够有效的。医生也可以通过电脑输入结果。鼠标。此外，他/她还可以在CT上用鼠标点击标记异常结果。结果表可以以excel格式显示并打印出来。与尘肺有关的词汇为“细结节影”、“疤痕及纤维化”及“结节影”。如上所述，我们可以成功地实现胸部筛查系统的改进。然而，我们无法使用移动CT进行实际的尘肺筛查，因为我们的做法要求无法被任何公司和工厂接受。

We have tried to improve lung cancer screening system using mobile spiral CT which was developed by our group and tried to aplly this system to the screening for pneumoconiosis.Regarding an improvement of the screening system using spiral CT, we accomplished a CT evaluation system comparig previous CT image and keyless reporting system in collaboration with researchers of NTT cyber-solution research institute. The CT image data were converted to DICOM format and stored in the PC server together with genearal information data of examined bersons. When we draw a previous CT on a CRT showing present CT image, a sorting method by their names written in Japanese was effective sufficiently. Also it bacame to be possible that a doctor enter the result by cricking with PC. mouse. Beside he/she can put a mark at abnormal findings on the CT by the mouse crick. The resulst table can be revealed in Ecxel format and be printed out. The terms in relation to pneumoconiosis were "fine nodular shadow","scar and fibrosis" and "nodular shadow".As mentioned above we could achieve an improvement of chest screening system successfully. However, we could not carry out practical pneumoconiosis screening using mobile CT, because our request of the practice could not be accepted by any companies and factories.
