MINT Goals
Provide fast transport of DICOM studies over Web• Eliminate end of study problem• Storage commit is inherent
Provide an Web based DICOM Storage System• Long Term Archive• Caches
Eliminate the need for PACS migrations• Supports studyUIDs across domains• A MINT store can be walked and indexed by any authorized
application, i.e. it can support multiple PACS

Essence of MINT
RESTful Interface Study create, read, update, delete, copy, move Studies are Normalized, i.e. no metadata duplication DICOM objects addressed by UIDs UIDs are global across domains Entire study can be transmitted in one message Eliminates need for migration
• PACS must percolate all changes to storage MINT Store can be indexed by any authorize app

URI WADO
One object at a time Only one use case in Sup148 “Get an object”
![Page 7: MINT Web Based DICOM Storage. MINT is designed for the efficient transport and storage of DICOM objects using Web technologies MINT Store PACS Modalities](https://reader035.vdocuments.us/reader035/viewer/2022062407/56649d925503460f94a78e01/html5/thumbnails/7.jpg)
How MINT is Like URI WADO
Designed for Web HTTP support for DICOM study object retrieval
![Page 8: MINT Web Based DICOM Storage. MINT is designed for the efficient transport and storage of DICOM objects using Web technologies MINT Store PACS Modalities](https://reader035.vdocuments.us/reader035/viewer/2022062407/56649d925503460f94a78e01/html5/thumbnails/8.jpg)
How MINT is Different from WADO
Focused DICOM transport & storage using HTTP It only supports DICOM objects
(not rendered objects – but could be extended) It normalizes metadata Creates, Updates and Deletes DICOM studies Uses REST style resources rather than parameters
to identify studies, series and objects
![Page 9: MINT Web Based DICOM Storage. MINT is designed for the efficient transport and storage of DICOM objects using Web technologies MINT Store PACS Modalities](https://reader035.vdocuments.us/reader035/viewer/2022062407/56649d925503460f94a78e01/html5/thumbnails/9.jpg)
How MINT is Different from WADO(cont)
It supports resources for Studies, Series, Objects, Types & Jobs

Problems MINT Addresses
Study size increasing• Time to display images increasing
Multiple mini-PACS w/ separate caches• Speed• Proprietary data• Increases complexity
DICOM Push model Migrating the archive when changing vendors Need for enterprise archive

• Metadata • Includes all non binary attributes found in all DICOM SOP
instances in a given study• Normalized attributes according to DICOM Information
Model• Is accessed independently from the binary data• References binary data items using their id
• Binary Items • Can be retrieved in batch or individually• Are identified by study scoped ids (bids or binary ids)

MINT is Web Based
RESTful interface to DICOM studies• Transport = HTTP 1.1 (includes chunking)
Leverages existing technologies Transmission through firewalls
• Encoding XML • Operations
CRUD (Create, Retrieve, Update, Delete) Search Notification
• Data Model = DICOM Part 3 Leverages existing web technologies Allows transmission through firewalls
