ihe, solution for integration of information systems and pacs

Pacs is used as a way to store images and matches well with the workflow in the radiology department and can spread toother parts of hospital. integration with other pacs and other hospital systems like radiology information system (ris),hospital information system (his), and electronic patient records has been completely done, but there are still problems.pacs also provide good conditions for setting up tele-radiology. the next step for pacs is where hospitals and healthcare organizations share photos in integrated electronic patient record. among the different ways for sharing photosbetween different hospitals, ihe (integrating the health care enterprise) standard indexes the cross-enterprise documentsharing profile (xds) and allows sharing photos from various hospitals even if their pacs has different brands anddifferent vendors.application of xds is useful for sharing images between health care organizations without duplicating them in a centralarchive. images need to be indexed in a central registry. in the xds profile, ihe defines an indexing mechanism forprinting and indexing images in the central document registry. ihe also defines mechanisms to be used by each hospitalto retrieve images, regardless of storing them in hospital pacs.
