The PHOENIX Radiology Consultant is a rule-based expert system which assists physicians in planning radiological work-up strategies. This article describes the methods used to create and validate the system's knowledge base. The feasibility and acceptability of PHOENIX were tested for two years in a clinical trial. During this period, the system was used 1,421 times, an average of 13.7 times per week, primarily by medical students and nonradiologist physicians. Much of the system's use occurred at night and on weekends, when the radiology department was not fully staffed. Several physicians were enlisted to further evaluate the utility of the system. The results of their evaluation indicate that an expert system that helps physicians select diagnostic-imaging studies can serve as a useful and informative component of a radiology information system, and is particularly useful for medical students and physicians in training.
凤凰放射学顾问系统是一个基于规则的专家系统，可协助医生制定放射学检查策略。本文描述了用于创建和验证该系统知识库的方法。在一项临床试验中，对凤凰系统的可行性和可接受性进行了为期两年的测试。在此期间，该系统被使用了1421次，平均每周使用13.7次，主要使用者是医学生和非放射科医生。该系统的使用大多发生在夜间和周末，此时放射科人员配备不足。几位医生被招募来进一步评估该系统的效用。他们的评估结果表明，一个能帮助医生选择诊断性成像检查的专家系统可以成为放射学信息系统中一个有用且信息丰富的组成部分，尤其对医学生和正在接受培训的医生很有用。
