The ASH Image Bank is a comprehensive reference and teaching tool that is widely accessible to physicians and hematology students around the world. The images are presented in a digital, case-based format that allows both the images and text to be searched, cross-referenced, and hyperlinked to other cases as well as other educational resources, including Hematology, the Education Program Book, the ASH Teaching Cases, and the syllabus from the ASH Self-Assessment Program. In addition to the case studies, the Image Bank includes a collection of basic atlas images.
