DEVELOPMENT AND EVALUATION OF ORAL REPORTING SYSTEM FOR PACS

Experimental workstations for oral reporting and synchronized image fi ling have been developed and evaluated by radiologists and referring p hysicians. The file media is a 5.25-inch rewritable magneto-optical di sk of 600-Mb capacity whose file format is in accordance with the IS&C specification. The results of evaluation tell that this system is sup erior to other existing methods of the same kind such as transcribing, dictating, handwriting, typewriting and key selections. The most sign ificant advantage of the system is that images and their interpretatio n are never separated. The first practical application to the teaching file and the teaching conference is contemplated in the Osaka Univers ity Hospital. This system is a complete digital system in terms of ima ges, voices and demographic data, so that on-line transmission, off-li ne communication or filing to any database will be easily realized in a PACS environment. We are developing an integrated system of a speech recognizer connected to this digitized oral system.
