Abstract<和文抄録> 本邦における核医学画像処理用電算機システムの歴史と現状について述べるとともに, 電算機規格化委員会の調査結果を中心に, システムの使用状況, 各種問題点の検討と将来像について検討を加えた. さらに, これらの調査結果に基づいた核医学画像処理用電算機システムの試作を行った. 本邦でシステムが最初に導入された昭和43年以降, 昭和58年上半期現在までの核医学用電算機システムの普及は全国で571台に達し, 国産3社の製品が約3/4を占めている. 委員会調査では, 現有機種に対する満足度は低く, 規格化・標準化の要望が高かった. システムの使用状況は, 放射線技師が中心で使用され, 日常検査では, 心・肝に多くの時間がさかれ, データ保存はMT, ハードコピーには白黒フィルムとカラーポラロイドが汎用されている. 故障は, 年均平3回, ディスクとMTに関するものが多い. システムの将来像としては, 32ビットCPU, 光ディスク, 自動フィルムチェンジャー, 日本語の使用などが希望され, 総合画像処理ならびに病院用トータル・システムとの連絡性も考慮する必要がある. これらの要望を勘案し, 現在, 大阪医科大学では, Eclipse MV/6000を使用した試作システムを開発中であり, その構成ならびに結果の一部を呈示した.

AbstractThe history and evaluation of image processing computer system in the field of nuclear medicine were reported in this presentation, mainly on the basis of enquete survey to users which was performed by Committee of Standardization of Image Processing Computer System, (chairman Prof. Hiroaki Akagi) , in Japan Society of Nuclear Medicine (JSNM) . After the results of enquete survey, an experimental system, which would be expected in next generation, was discussed and demonstrated. 1. History of the system According to the reports by makers, sales of image processing computer system started at 1968, and now in 1983, total number of installed in Japan, came up to 571, where there were only 114 in 1977, and three quarters of the market share in Japan were by 3 Japanese makers, such as, Shimadzu, Toshiba and Hitachi. 2. Results of enquete survey The enquete survey by Committee of Standardization on Image Proceesing Computer System in JSNM showed strong demands for the improvement of conventional system as well as the standardization for the compatibility among the systems of each makers. The institutes satisfied with current systems were not more than 20 out of 168 (11.9%) , and request to standardization was in 119 (70.8%) . 1) Additional results The use of current systems in daily examinations was carried out by radiological technicians (71.1%) , both in static and dynamic images. Target organs were mainly heart (4.79 hours a week) and liver (3.81 hr/wk) , and the data storage was by MT and hardcopies were mainly on black and white X-ray film or colour Polaroid. Systems faults were reported as 3 times of 15 hours a year on average, which devices were mainly magnetic disks and MT. 2) Future system Future systems expected in the enquFte were computers with 32 bits CPU, optical disks for mass memory, automatic mult-film imager, input of Japanese characters and by voice, and report-writing in Japanese. And data exchange between the system and host of hospital computer should be on consideration. 3. Experimental system Upon the whishes an experimental system was designed and arranged in our laboratory using Ecripse MV/6000, in co-operation with Shimadzu and Nippon Data General. Some results were demonstrated but it was still on progress of the software, and inter-connection with the hospital computer system was under planning step. 4. Summary Nuclear Medicine had much shorter history compared to that of ordinary roentogenology, but the application of image processing method was used earlier, especially in the field of usage of computer system. But there occured some problems in compatibility of the system caused by rapid development of computers. In this presentation, some suggestion would be found for future computer system in data processing in Nuclear Medicine.
