Nijmegen Database

All 40 images in this dataset show one or more clusters of microcalcifications. The mammograms are from 21 different patients. Both benign and malignant cases are included. (Benign cases: 1,2,7,8,9,10,14). The position and size of the microcalcification clusters were marked by two expert radiologists, based on all patient data available (different views, magnifications). These annotations were entered into the computer as circular areas and are stored in separate files (extension mrk). Pixel level output files of the microcalcification detection program on the public database of 40 mammographic images are included. This directory also contain files that give the lookup tables for conversion of the image files using adaptive noise equalization The 40 images in this dataset have been made available by the Department of Radiology, University Hospital Nijmegen, PO box 9101, The Netherlands. Questions can be addressed to Dr. Nico Karssemeijer (e-mail Publications making use of this dataset should mention this using the following acknowledgment: 'Images were provided by courtesy of the National Expert and Training Centre for Breast Cancer Screening and the Department of Radiology at the University of Nijmegen, the Netherlands'. These images are also available via anonymous ftp to

LLNL/UCSF Database

We, at Lawrence Livermore National Laboratories (LLNL), along with University of California at San Fransisco (UCSF) Radiology Dept. have developed a 12 volume CD Library of digitized mammograms featuring microcalcifications. For each digitized film image, we have 2 associated "truth" images (full size binary images) that show:

Along with the "truth" images, we provide a file with case history, radiologists comments, and other information.

The library contains 198 films from 50 patients (4 views per patient, but only 2 views from one mastectomy case), selected so as to span a range of cases of interest. These films were digitized to 35 microns. Each pixel was sampled to 12 bits of grayscale. As a result, each digitized mammogram results in image that is about 50 megabytes in size, for a total of nearly 6 gigabytes for the entire library.

The films were selected to present 5 normal, average, healthy cases (previous normal mammograms and no history of ultrasound, magnification views, biopsy, etc.), 5 normal but difficult cases (with either dense or fibrous breasts, implants, or asymmetric tissue), 20 cases of obviously benign microcalcifications (with at least 3 years of follow-up without change or developing cancer), 12 cases of suspicious, benign microcalcifications, (note: all these benign cases had either a biopsy or a diagnostic mammogram plus at least 3 years of subsequent follow-up without change or developing cancer), and 8 cases with a malignant cluster of microcalcifications, biopsy proven.

The set is available for US $100 to cover our reproduction costs. For more information on the database, send e-mail to

Mammographic Image Analysis Society (MIAS) Database

The images in this database were scanned with a Joyce-Loebl microdensitometer SCANDIG-3, which has a linear response in the optical density range 0-3.2. Each pixel is 8-bits deep and at a resolution of 50um x 50um. Further details of performance can be found in:

The data is in compressed format and before use will have to be uncompressed using the UNIX `uncompress ' command.

There is an accompaining License Agreement. MIAS is a nonprofit organization, and there is a small fee for a copy of the database on an 8mm Exabyte tape. Ordering information can be found at the MIAS Website

Washington University Digital Mammography Database

This database contains digitally acquired images of pathologically proven breast pathology. Each case consists of a single scout image of a breast lesion obtained during the course of stereotactic core needle biopsy. Cases are organized according to lesion histopathology. Patient demographic data will be added to the database in the near future.

Images have been acquired on a LORAD CCD-based, stereotactic core biopsy table. Each image is 512x512 pixels in size with 12 bits of grey scale data per pixel. Icons of images are available for viewing on the Web page. Raw image data can be downloaded via FTP to any Unix-based system.

Our intent in making these images available is to foster image processing research in digital mammography. To date, most publicly accessible digital mammography databases are made from film digitized mammograms. Image processing on such images does not allow the investigator to take full advantage of the unique characteristics of directly acquired digital data. It is our hope that the availability of digitally acquired mammographic data will aid the further development and acceptance of digital mammography.
