1. Purpose of research were :(1) Experimental system for clinical trial use of electronic storage of medical images must be constructed, and radiologists and radiological technologist must use the system to check clinical effectiveness of it in the radiological practice. Especially capabilities of extracting diagnostic information musted be proven by checking image quality.(2) Quantitative measurement of clinical effectiveness for economical expense must be tried and the results must be applied for the decision making of installation of such electronical storage system of medical images.(3) Social impact of the results of such systems in the field of cooperation of hospitals with clinics, teleradiology, diagnostical education, cancer therapy as well as patient outcome must be proven.2. Results of research (1) and (2) below according to the purpose of the research of item (1) above are described as follows. Result of research (3) below according to the purpose of the research of item (2 … More ) above is described as follows.(1) Integration of HIS/RIS/PACS has been evaluated for these 5 years in Osaka University Hospital. Evaluation data were acquired by means of methods of time study for these 5 years. Quantitative evaluation of clinical outcome brought basic data for optimized design of PACS of next generation.(2) PACS which has more than 400 units of image display terminals for HIS functions has been evaluated by Osaka University. This HIS/RIS/PACS has functions of radiological diagnosis and reference.(3) Cost effectiveness of both experimental and practical systems for electronical storage of medical images were tried to be measured in terms of :a) Comparison of economical expenses for electronical storage of moving pictures such as digital cine-angiography applying DVD technology, MO technology and image data compression technologies was carried out.b) Economical expenses for hardware resources and the results of quantitative simulation of PACS performance such as response time employing such hardware resource were compared each other. Optimization of cost effectiveness was tried to get optimized design of PACS before purchasing hardware and software, and introducting such systems. Less

1. 研究的目的是：(1)建立医学影像电子存储临床试用实验系统，放射科医师和放射技师在放射实践中使用该系统检验其临床效果。特别是提取诊断信息的能力必须通过检查图像质量来证明。(2)为了节省费用，必须尝试定量测量临床效果，并将结果应用于安装此类医学影像电子存储系统的决策。(3)必须证明这些系统在医院与诊所、远程放射学、诊断教育、癌症治疗以及患者预后等领域的合作结果的社会影响。根据上述第(1)项的研究目的，下文第(1)项和第(2)项的研究结果如下：根据上述（2…More）项的研究目的，下面(3)项的研究结果如下：(1)对大阪大学医院5年来HIS/RIS/PACS的整合进行了评估。评价资料采用时间研究方法获取。临床效果的定量评价为下一代PACS的优化设计提供了基础数据。(2)拥有400多台HIS功能图像显示终端的PACS已通过大阪大学的评估。该HIS/RIS/PACS具有放射学诊断和参考功能。(3)尝试从以下方面衡量医学图像电子存储实验系统和实际系统的成本效益：a)比较了应用DVD技术、MO技术和图像数据压缩技术的数字电影血管成像等运动图像电子存储的经济费用。b)比较硬件资源的经济费用和采用该硬件资源的PACS性能的响应时间等定量仿真结果。从成本效益的角度出发，在软硬件采购和系统引进前，对PACS进行优化设计。少
