Content-based image retrieval (CBIR) has often been proposed to assist medical decision making in complement to textual information search. However, applications of this novel technology have rarely reached the end users. The study presented in this paper describes the design and setup for performing pilot user tests in order to assess a medical information retrieval system that supports CBIR with the goal of having more detailed tests with an updated system. Five individuals with medical education participated in the study at the University hospitals of Geneva. They were recorded and observed while interacting with the system, and then provided feedback on the usability of the system. Participants seemed to understand the concept and practical uses of the new tools, and needed 10-15 minutes to feel confident with the system. The results of this pilot study will be used for improving the system functionalities as well as an input for designing a new iteration of larger-scale user tests among radiologists.
基于内容的图像检索（CBIR）常被提议用于辅助医学决策，以补充文本信息搜索。然而，这项新技术的应用很少能触及终端用户。本文所呈现的研究描述了进行试点用户测试的设计与设置，目的是评估一个支持CBIR的医学信息检索系统，以便在更新后的系统上进行更详细的测试。五名受过医学教育的人员参与了日内瓦大学医院的这项研究。在他们与系统交互时进行了记录和观察，然后他们就系统的可用性提供了反馈。参与者似乎理解了新工具的概念和实际用途，并且需要10到15分钟才能对系统感到自信。这项试点研究的结果将用于改进系统功能，同时作为为放射科医生设计新一轮大规模用户测试的一项参考依据。
