DICOM - The Early Years First implementations of DICOM focused on the

ability to send/receive images (i.e. Storage) Hospitals first used images from CT, MR, CR and

Secondary Capture, primarily in Radiology US, NM, X-ray quickly followed

Many modalities were connected via a DICOM Conversion Box – this still exists today

Secondary Capture used by framegrabbers, film digitizers, etc. – this still exist today

Storage enabled the first trueStorage enabled the first true““multi-vendor” image integrationmulti-vendor” image integration


DICOM - The Early Years Most common image transfer was between

modalities and workstations PACS archive products did exist but mostly based

upon proprietary designs (receive DICOM then convert) DICOM Query/Retrieve was used to “pull images”

from modalities (mainly only CT, MR) Query/Retrieve from PACS archive typically only

used via 3rd party workstation – often true today

Image transfer is the first DICOMImage transfer is the first DICOMfeature for all medical imaging specialtiesfeature for all medical imaging specialties


DICOM – Middle Years DICOM Print became widely used in 97’-98

(even “film-less” hospitals need print as backup to PACS)

Storage used in Cardiology, Radiation Therapy

DICOM specifications for dentistry, pathology, ophthalmology, endoscopy, and more

PACS starting to integrate with information systems (RIS), starting with Modality Worklist

Why Has DICOM BeenWhy Has DICOM BeenSo Successful?So Successful?


Too Many Reasons to Cover, But…. It starts with the DICOM Committees themselves

Worked long hard hours to provide specificationsthat can be practically implemented

Committees consist of vendors and users that are competitors but are able to put aside differences to provide a high quality standard

World wide participationDICOM is truly an international standard

Thanks to all my colleaguesThanks to all my colleaguesin all the DICOM Committees and NEMA!in all the DICOM Committees and NEMA!


Early and ContinuedDICOM Demonstrations

RSNA played an important role to educate and showcase DICOM to hospitals and vendors

Live DICOM “picture” images at RSNA (94’)

Mallinckrodt and Oldenburg CTN software for testing and use

Demonstrations in Europe and Japan Support of the US Department of Veterans Affairs

RSNA and HIMSSRSNA and HIMSSIHE continues to showcase DICOM IHE continues to showcase DICOM


The Technical Reason? Service/Object Pair (SOP) Class is what allows us

to successfully implement DICOM It’s what the DICOM Standard specifies It’s what the software developers implement to It’s what vendors test in their labs It’s what we integrate in our hospitals It’s our communication tool

(I need my modalities to integrate with the my RIS, ok, you implement Modality Worklist SOP Class)
