Description:

This collection compiles anonymous radiographs, which have been arbitrarly selected from routine at the Department of Diagnostic Radiology, Aachen University of Technology (RWTH), Aachen, Germany. The imagery represents different ages, genders, view positions and pathologies. Therefore, image quality varies significantly. All images were downscaled to fit into a 512 x 512 bounding box maintaining the original aspect ratio. All images were classified according to the IRMA code. Based on this code, 57 categories were defined. For 9000 images, these categories are transparent by the name of the folder. The remaining 1000 images without code are used as test data for the ImageCLEFmed 2005 competition.

• Training data: 9000 radiographs in 57 categories.
• Test data: 1000 radiographs without classification.
• Category names: medical terms characterizing the 57 categories in German and English languages.
