OPEN-i®: A Unique Image Search Engine

As the saying goes, “A picture is worth a thousand words.” While it can take hundreds or thousands of words to convey a complicated concept; a single image can easily do the same thing. OPEN-i® is the open access biomedical image search engine from the National Library of Medicine’s Lister Hill Center for Biomedical Communications. OPEN-i® is unique in its ability to index both the article’s text and images from the open source literature and biomedical image collections. OPEN-i® searches and retrieves both abstracts and images (including charts, graphs, clinical images, etc.)

You can conduct a search in OPEN-i® by typing your terms in the search box or by selecting a saved image. From the results display, hover your cursor over an image and a MEDLINE citation will pop-up.

The following limits can be applied to your searches:

OPEN-i® contains over 3.7 million images from about 1.2 million PubMed Central® articles; over 7,400 chest x-rays with over 3,900 radiology reports; 67,500 images from the NLM History of Medicine collection; and over 2,000 orthopedic illustrations, plus MedPix.

Images are obtained from the following sources:

Copyright for use of the images remains with the authors or the journal.
