项目摘要

From November, 1997 to the end of January, 1998, we carried out primary mass chest screenings using mobile spiral CT in T and C areas. In the area T the indivisuals checked up beccause of abnormal findings in the x-ray were introduced to various local general hospitals as conventional chest screening system based on the Tuberculosis Control Law or the Health and Madical Services law for the Aged. In the another area the indivisuals checked up were examined in our university hospital or the affiliated hospital where our colleagues work. The numbers of individuals of area T and C were 782 and 765, respectively. The number of the person who needs to have further examinations in the area T and C were 33 (4.2%) and 40(5.6%), respectively. Finally, one was diagnosed as lung cancer and he underwent surgery in the area T, and five were diagnosed lung cancer and three of them underwent surgery. Although the all persons who checked up in the area C received definite diagnosis, in the area T, six of the 33 had not underwent further examination, In order to complete the diagnosis for the checked up persons, further examination should be done by the doctors who understand the value of chest screening.Through the experience written above, we have made the form for the result of CT reading. We have had no trouble to perform chest screenings.The CT readings were carried out using cathode-ray tubes(CRT). However, from the next year the comparison with previous CT image on the CRT will be necessory. We have studied about it with the group of NTT Human Interface, and the softwares have developed, By the software, the data of CT machine is converted to the data for the personal computer, and then on a CRT of the computer two CT images of the present CT and previous one are displayed. Vie are sure that our study will develop favorably using this software.

1997年11月至1998年1月底，我们用移动的螺旋CT在T区和C区进行了胸部肿块初筛。在T区，根据《结核病防治法》或《老年人保健和医疗服务法》，将因X光检查发现异常而接受检查的个人作为常规胸部检查制度引入各地方综合医院。在另一个地区，个人检查是在我们的大学医院或附属医院，我们的同事工作。T区和C区的个体数量分别为782和765。T区和C区需要进一步检查的人数分别为33人（4.2%）和40人（5.6%）。最后，一个被诊断为肺癌，他在T区接受了手术，五个被诊断为肺癌，其中三个接受了手术。虽然C区检查的所有人都得到了明确的诊断，但在T区，33人中有6人没有做进一步的检查，为了完成对被检查者的诊断，进一步的检查应该由了解胸部筛查价值的医生来做，通过上述经验，我们制作了CT阅读结果表。我们在进行胸部检查时没有遇到任何困难，CT读数是用阴极射线管（CRT）进行的。然而，从明年开始，将有必要与CRT上的先前CT图像进行比较。本课题组与NTT人机界面小组一起进行了相关的研究，并开发了相应的软件，该软件将CT机的数据转换为PC机的数据，然后在PC机的CRT上显示当前CT和前一个CT的两幅CT图像。我们相信，使用该软件，我们的研究将取得良好的发展。
