Integrated research on assessment of clinical effectiveness of electronical storage of, Prosses medical images

1.研究目的：（1）建立医学影像电子存储临床试验系统，供放射科医师和放射技术人员使用，检验其在放射学实践中的临床效果。特别是诊断信息的提取能力必须通过检查图像质量来证明。(2)必须尝试以经济的代价对临床效果进行定量测量，并且必须将结果应用于安装这种医学图像电子存储系统的决策。(3)必须证明这种系统在医院与诊所、远程放射学、诊断教育、癌症治疗以及患者结局合作领域的结果的社会影响。2.根据上述（1）项的研究目的，下面描述以下研究（1）和（2）的结果。根据第（2）项的研究目的，以下是研究结果（3 关于我们 ）的描述如下。(1)在大坂大学医院对HIS/RIS/PACS的集成进行了5年的评价。通过时间研究的方法获得了这5年的评价数据。临床结果的定量评价为下一代PACS的优化设计提供了基础数据。(2)大坂大学对拥有400多台用于HIS功能的图像显示终端的PACS进行了评估。该HIS/RIS/PACS系统具有影像诊断和参考功能。(3)对实验性和实用性医学影像电子存储系统的成本效益进行了以下方面的衡量：a）比较了采用DVD技术、MO技术和图像数据压缩技术的运动图像电子存储系统（如数字电影血管造影）的经济费用，B）比较了硬件资源的经济费用和采用这种硬件资源的PACS性能（如响应时间）的定量模拟结果。在采购PACS系统的硬件和软件以及引进PACS系统之前，尝试进行成本效益优化，以获得PACS系统的优化设计。少

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
