This research consists of the management of large amount of image information, digitalizing the analog film data suitable for interpretation, archiving and retrieving the digital images, and report making. During the four year research period, this electronical field of technology has dramatically advanced owing to the foregoing computer sciences.Film data are very important. The X-ray films of a specific patient over a period of time are unique and cannot be reproduced if they are lost. Therefore, films must be stored carefully. But, it is not easy task to store films for a long period, because films are very heavy and bulky. A large storage space is required. Microfilming or miniaturization of films is an way of easy storage and PACS way is another. Newly founded medical schools adopted the microfilming for a long time, but efficient digitalizing method of analog microfilms was necessitated, because old original films have been abandoned and the valuable analog data in the microfilms … More must be transmitted to the digital forms in the age of PACS.Direct input of microfilm data by zooming lens attached to the TV-camera is displayed large enough on CRT monitor and converted from analog to digital by computer. This enabled to complete the flow chart of storage and observation systems for analog/digital image information.Digitalization of CCD and laser scan methods was fundamentally investigated for test-charts, simulation objects and clinical films as well.As for the reporting system, voice input of dictation was tested comparing other methods. Clinical information is essential to maintain the better reports of the radiological examinations to ordering or referring in Radiology Information System (RIS).Total Information System (TIS) includes reporting as well as image management and for higher integration of TIS, Mini-PACS and Case Information System (CIS) must be invested. Image Management and Communication Systems (IMACS) and TIS function to multi-modalities and data storage is investigated. Less

该研究包括大量影像信息的管理、适合判读的模拟胶片数据的数字化、数字化影像的存档和检索、报告的制作。在四年的研究期间，由于计算机科学的发展，这一电子技术领域取得了巨大的进步。特定患者在一段时间内的X光片是唯一的，如果丢失则无法复制。因此，电影必须小心保存。但是，由于胶片非常笨重，要长时间储存胶片并不容易。需要很大的存储空间。胶片的缩微或小型化是一种易于存储的方式，PACS方式是另一种。新建医学院长期以来一直采用缩微胶片，但由于旧的原始胶片已被抛弃，而缩微胶片中有宝贵的模拟数据，因此需要高效的模拟缩微胶片数字化方法 ...更多信息 在PACS时代，缩微胶片数据必须以数字形式传输，通过电视摄像机上的变焦透镜直接输入缩微胶片数据，在CRT显示器上显示足够大的图像，并由计算机将其从模拟转换为数字。完成了模拟/数字图像信息的存储和观察系统的流程图，对测试图表、模拟物体和临床胶片的CCD和激光扫描方法的数字化进行了初步研究，对报告系统进行了语音听写输入的测试，并与其他方法进行了比较。放射信息系统（RIS）中的临床信息是保证放射学检查报告及时、准确、及时的必要条件，全面信息系统（TIS）包括报告和影像管理两部分，要实现TIS的高度集成，必须投资Mini-PACS和病例信息系统（CIS）。研究了图像管理和通信系统（IMACS）和TIS对多模态和数据存储的功能。少
