iScout: an intelligent scout for accessing and navigating large image sets in a PACS.

A new software tool for PACS, called iScout (intelligent scout), has been developed and optimized for a radiology workstation. The purpose of iScout is to display an overview of a large image series, allowing the user to select images for priority downloading from a PACS server to a PACS workstation. This allows radiologists to reduce the delays that are associated with downloading hundreds or even thousands of images. Several schemes that semiautomatically manage the download process are presented along with tests to measure performance. The results of the tests confirm that priority downloading provides faster access to images in large image series and that the time savings increase in proportion to the study size.
