Minimum Required DICOM Tags for Functionality


This article lists the minimum DICOM tags Flywheel requires for certain features.

Instruction Steps

The OHIF Viewer

The OHIF viewer requires the following tags:

DICOM Connector

The default DICOM tags that the Connector uses to upload data to Flywheel and update key field values are listed below. It is possible to customize the Connector configuration to use alternative DICOM tags for some of the fields. Mapping the images to the Flywheel hierarchy in the database could be impacted if those values are not available. Also, some Flywheel field values might not not be populated if DICOM tag values are not available. Learn more about how the DICOM connector uploads images.

Flywheel Hierarchy Field Mappings to DICOM Tags

Flywheel Field DICOM Tag Name DICOM Tag VR
Group ID
Project Label
Subject ID
Study Comments* (0032,4000)*
Session UID Study Instance UID (0020,000D) UI
Session Label Study Description (0008,1030) LO
Acquisition UID Series Instance UID (0020,000E) UI
Acquisition Label Protocol Name (0018,1030) LO

*It is possible to customize which DICOM field(s) Flywheel should configure to capture Routing String values (Group, Project, and Subject)
