USECASES

DICOM defined

Supplement 92 reference/overview


Use Case #1: Interoperability without digital radiographic equipment using DICOM Removable Media (RM).

This use case scenario demonstrates the use of DICOM RM as a means of communicating diagnostic radiographic images to a practitioner who does not have a digital imaging system.

Use Case #2: Interoperability between different vendor’s digital radiographic equipment using DICOM Removable Media (RM).

This use case scenario demonstrates the use of DICOM RM as a means of transferring diagnostic radiographic images between dental practices with different vendor’s digital imaging systems.

Use Case #3: Conversion of radiographic image archive from one vendor’s digital imaging system to another’s using DICOM Removable Media (RM).

This use case scenario demonstrates the use of DICOM RM as a means of converting an entire dental practice radiographic image archive between different vendor’s digital imaging systems, thereby maintaining the dentist investment in digital imaging.


Use Case #4: Interoperability between a dental practice using conventional film radiography and a specialty dental practice with digital radiography using DICOM Network Storage and Retrieval (NSR).

This use case scenario demonstrates the use of DICOM NSR and DICOM RM as a means of integrating both conventional film-based and digital radiography.

Use Case #5:Communication of digital radiographic images between a private practitioner and an interested third-party using DICOM Storage and Retrieval (NSR).

This use case scenario demonstrates the use of DICOM NSR as a means transmitting digital radiographic studies between dental practices using a secure third-party DICOM server.

Use Case #6: Interoperability between a dental practice management system and a digital radiography system using DICOM Modality Worklist (MWL).

This use case scenario demonstrates the use of DICOM MWL as a means of integrating information from a dental practice management system to a digital imaging system.


  • e.g. Use Case #4: Interoperability between a dental practice using conventional film radiography and a specialty dental practice with digital radiography using DICOM Network Storage and Retrieval (NSR).

  • This use case scenario demonstrates the use of DICOM NSR and DICOM RM as a means of integrating both conventional film-based and digital radiography.

  • A new patient arrives at a dental specialist office with conventional film intra-oral and extra-oral radiographs. The receptionist creates a new record for the patient in their digital imaging system and scans these films with a x-ray film scanner. The scanned images are stored to the DICOM server.

  • The specialist, using his/her digital imaging system, performs a DICOM Query and retrieves the appropriate images from the local server using DICOM Retrieve.

  • Additional digital extra-oral and/or intra-oral images are taken. The dentist views the images on his workstation.

  • The receptionist creates a DICOM RM CD with a copy of the complete set of images for the patient to take back to her referring general practitioner. This CD has the capabilities as previously discussed.

DICOM Connecting Dentists


ADA Interoperability 2004 Activity Sponsors using conventional film radiography and a specialty dental practice with digital radiography using DICOM Network Storage and Retrieval (NSR).


Ongoing activities
Ongoing Activities using conventional film radiography and a specialty dental practice with digital radiography using DICOM Network Storage and Retrieval (NSR).

  • Standardization of digital x-ray virtual mounts, including variation in the intra-oral full mouth series (approved new DICOM work item). - WG22.

  • Development and implementation of a Media Application Profile Supplement for dental color photographic (VL) images – or appropriate correction package to existing standard. - WG22.

  • Examination of application of existing DICOM standards for e-mail attachment of images. - ADA WG12.1 (ADA TR).


In the longer term
In the longer term… using conventional film radiography and a specialty dental practice with digital radiography using DICOM Network Storage and Retrieval (NSR).

  • Dental applications of WADO.

  • Dental VL virtual mounts.

  • Creation of templates for structured reporting.

  • Development of guidelines for presentation states including overlays used in dentistry.

  • DICOM and 3-dimensional imaging issues for dentistry (e.g. Cone Beam CT and Tomosynthesis).

  • Evaluation of existing objects or current work items for use in dental imaging.
