Minumum Required DICOM Tags for Functionality
Introduction
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 | Study Comments* | (0032,4000)* | |
| Project Label | |||
| Subject ID | |||
| 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)
Flywheel Field Mappings to DICOM Tags
If these values are not present in the DICOM tags, then the Flywheel timestamp will be blank
| Flywheel Field | DICOM Tag Name | DICOM Tag | VR |
| Timestamp | Acquisition Date | (0008,0022) | DA |
| Acquisition DateTime | (0008,002A) | DT | |
| Acquisition Time | (0008,0032) | TM | |
| If one set of DICOM tag values is not present then we try to use the other | |||
| Timestamp | Series Date | (0008,0021) | DA |
| Series Time | (0008,0031) | TM |
