At this time, the quality of a Whole Slide Image (WSI) is verified a posteriori by a technician or a pathologist. A WSI of insufficient quality needs to be scanned again. High-speed automatic quality assessment tools for WSI will therefore greatly improve laboratory workflow. We describe here a fast method to automatically assess WSI quality, with different tests such as blurri- ness, contrast, brightness and color, and to accept or discard them at the time of acquisition in less than a minute. Parameters are weighted by pertinence and a global score indicates whether the WSI is suitable for further use. This fast method, designed at first to improve laboratory workflow, is currently being implemented in a network of 27 French hospitals and public-private health in- stitutions in the Paris region. It may also be used as a calibration and quality control tool for WSI acquisition systems.
