The OPTIMAM Image Database (OMI-DB) project implements procedures used to collect and store mammographic images for research.

OMI-DB was initially developed as part of a research project called OPTIMAM which ran from 1st December 2008 until 30th November 2013. The project was funded by Cancer Research-UK & EPSRC Cancer Imaging Programme in Surrey, in association with the MRC and Department of Health (England). A further period of funding was provided by Cancer Research-UK with the abbreviated title OPTIMAM2 which ran from 1st December 2013 until 30th November 2018. A further grant provided funding for the on-going collection of images and the management of the database is provided by CRUK. A steering committee oversees the work. The database is hosted and managed by staff with permanent contracts of employment at the Royal Surrey County Hospital, Guildford.
