项目摘要

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

这项研究包括管理大量图像信息，数字化适用于解释，存档和检索数字图像以及报告制作的模拟膜数据。在四年研究期间，由于上述计算机科学，该技术的电子领域已经大大提高了。FILM数据非常重要。特定患者在一段时间内的X射线膜是独一无二的，如果丢失了，就无法再现。因此，必须仔细存放电影。但是，长期存放电影并不容易，因为电影非常笨重。需要一个较大的存储空间。膜的微填充或微型化是一种简单存储的方式，而PACS方法是另一种。 Newly founded medical schools adopted the microfilming for a long time, but efficient digitalizing method of analog microfilms was necessary, because old original films have been abandoned and the Valueable 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.这使得完成了用于模拟/数字图像信息的存储和观察系统的流程图。对CCD和激光扫描方法的数字化也从根本上研究了测试创建，模拟对象和临床膜以及报告系统的测试形式，比较了其他方法的语音输入。必须投资临床信息，以维持有关放射学信息系统（RIS）中订购或参考的放射学检查的更好报告。计数信息系统（TIS）包括报告以及图像管理以及TIS，MINI-PACS和案例信息系统（CIS）的更高集成。研究了图像管理和通信系统（IMAC）和TIS功能多模式和数据存储。较少的
