This paper presents the architecture of an image administration system that supports the medical practice in tasks such as
teaching, diagnosis and telemedicine. The proposed system has a multi-tier, web-based architecture and supports content-based
retrieval. The paper discusses the design aspects of the system as well as the proposed content-based retrieval approach.
The system was tested with real pathology images to evaluate its performance, reaching a precision rate of 67%. The detailed
results are presented and discussed.
