Series collection parameters are stored in a separate JSON file called params.json stored in the series directory. The JSON object is an array of key-value pairs. This can be used for MRI sequence parameters.
All DICOM tags are acceptable parameters. See this list for available DICOM tags https://exiftool.org/TagNames/DICOM.html. Variable keys can be either the hexadecimal format (ID) or string format (Name). For example 0018:1030 or ProtocolName. The params object contains any number of key/value pairs.
| Variable | Description | Example |
|---|---|---|
{Key:Value} | A unique key, sometimes derived from the DICOM header | Protocol, T1w FieldStrength, 3.0 |
