Evaluation Research on Data Compression and Storage; Image Transfer and Interpretation; and Report Making, with Special Reference to Digitalized Images.

本研究包括对大量影像信息的管理，对适合解译的模拟影像数据进行数字化处理，对数字影像进行归档和检索，以及制作报告。在四年的研究期间，由于前面提到的计算机科学，这一电子技术领域取得了巨大的进步。电影数据非常重要。一个特定病人在一段时间内的x光片是唯一的，如果丢失就无法复制。因此，胶片必须小心保存。但是，由于薄膜非常重，体积很大，因此长期储存薄膜并不是一件容易的事。需要较大的存储空间。胶片的缩微或小型化是一种便于存储的方法，PACS是另一种方法。新成立的医学院校长期采用缩微胶片，但由于旧的原始胶片已被废弃，缩微胶片中宝贵的模拟数据在PACS时代必须更多地以数字形式传输，因此需要高效的模拟缩微胶片数字化方法。通过附在电视摄像机上的变焦镜头直接输入缩微胶片数据，在CRT显示器上显示足够大的数据，并由计算机将模拟数据转换为数字数据。这使模拟/数字图像信息的存储和观测系统流程图得以完成。对测试图、模拟对象和临床影像的CCD和激光扫描方法的数字化进行了基本的研究。对于报告系统，对比其他方法，对听写语音输入进行了测试。临床信息是保持更好的放射检查报告的必要条件，以便在放射信息系统（RIS）中订购或参考。总信息系统（TIS）包括报告和图像管理，为了使TIS更好地集成，必须投资Mini-PACS和案例信息系统（CIS）。研究了图像管理和通信系统（IMACS）和TIS在多模态和数据存储方面的功能。少

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
