Multimedia Database Tool

The Multimedia Database Tool (MDT) provides text-searchable access to databases containing both text and images. With the MDT, users may use a graphical user interface to pose a query based on values of text fields (including numeric values), and retrieve database records, including associated images, that satisfy the query. The MDT display is divided into scrollable areas for the returned text, and for the returned images. The returned data may be downloaded to the user’s local computer. Images may be displayed in reduced or expanded size. The MDT is designed to accommodate any text/image database which fits into a general data model in which the primary structure is a patient node having visit nodes; data fields may be associated with each node type, and images may be associated with visits. The two initial databases used in the MDT are the National Cancer Institute (NCI) Guanacaste and ALTS databases, which include 100,000 uterine cervix “cervigram” images. A typical query of one of these databases might be to find all records for women who had an HPV test positive for HPV type 16. The current MDT uses Java client/server architecture, but the MDT is being re-architected to run as a Web browser application.
