Abstract
For mass image data analysis in hospitals, we have built an integrated platform for the development and assessment of various types of image analysis software such as computerized detection of lesions. It mainly consists of a set of clinical image databases, and a clinical server with web-based interfaces for launching analysis software and for viewing and evaluating analysis results. The image databases are employed for the registration of a sufficient number of clinical cases for machine learning in computer-assisted detection (CAD) software development. In addition, the clinical server collects data for evaluating the interpretation performance of radiologists as well as that of the CAD software.
