Medical Image Database for Developing Computerized Diagnosis System

本研究计画旨在建立医学影像资料库，以开发医学影像电脑诊断系统。在日本，乳腺癌、胃癌和肺癌非常流行。乳腺X线摄影数据库由医学图像计算机辅助诊断学会开发，并向学会成员开放。因此，本课题的主要研究目标是建立胃X线图像数据库和胸部X线、CT图像数据库。在两年的时间里，开发了以下数据库：胃X射线图像数据库：它包括76张计算机X射线摄影图像，其中65张图像包括胃癌;胸部CT图像数据库：它包括用于集体筛查的CT图像和用于密切检查的CT图像，分别包括70例和7例。它包括常规胸部X光图像数据库和胸部透视图像数据库，每个数据库包括50个病例，每个数据库包括读取图像的重要信息，如癌性肿瘤的位置，其草图，这对开发计算机化医学影像诊断系统具有重要意义。

This research project has been organized to develop medical image database which can be used to develop computerized diagnosis system of medical images. In Japan, breast cancer, gastric cancer and lung cancer are very popular. Mammography database has been developed by the Society of Computer Aided Diagnosis of Medical Images and it is open to the society members. Therefore, development of stomach X-ray image database and chest X-ray and CT image databases is the primary object of this research project. During two years, the following databases have been developed.Stomach X-ray image database : It includes 76 Computed Radiography images in which 65 images include gastric cancer.Chest CT image database : It includes both CT images for mass screening and for close examination, and it includes 70 cases and 7 cases, respectively.Chest X-ray image database : It includes conventional chest X-ray image database and chest fluoroscopy database, and each of them includes 50 cases.Each database includes important information to read images such as locations of cancerous tumors, their sketches, and so on. They will be very useful to develop computerized diagnosis system of medical images.
