In a move to update a collection of medical slide images and improve access to high-quality medical images for postgraduate teachers at the Institute of Child Health and Great Ormond Street Hospital for Children, a new collection of scanned slide images was created on Kodak Photo CD discs. Each image was available in five different resolutions. The images were catalogued in an image database by diagnosis, date, patient registration number, and anatomical view. Images could be accessed using simple search protocols and output to digital files, slides or prints.
