DICOM Attribute Coercion Parameters - dcm4che/dcm4chee-arc-light GitHub Wiki

Merge Attributes Options

{AttributeTagOrKeyword}={value}
{SequenceTagOrKeyword.AttributeTagOrKeyword}={value}
{value} may contain an AttributeTagOrKeyword. In this case the AttributeTagOrKeyword inside {value} will be replaced by the value of that attribute in the original dataset.
Above examples can be combined with various Formatting Options
To nullify an attribute value, just specify attribute without any value {AttributeTagOrKeyword}= or {SequenceTagOrKeyword.AttributeTagOrKeyword}=
To remove the attribute from the dataset, specify the attribute name/tag followed by !, i.e. {AttributeTagOrKeyword}! or {SequenceTagOrKeyword.AttributeTagOrKeyword}!

Formatting options available to merge DICOM dataset attributes are :

Attributes format	Meaning	Example
`slice`	Slice attribute value from a certain index / position (optionally upto an end index / position)	`PatientID={PatientID,slice,3}` `PatientID={PatientID,slice,3[,7]}`
`hash`	Hash the value of specified attribute	`IssuerOfPatientID={00100010,hash}-{00100030}` `AccessionNumber=ACC-{StudyInstanceUID,hash}`
`upper`	Convert specified attribute's value to upper case	`AccessionNumber={AccessionNumber,upper}`

Some examples :

PatientID=JMS{PatientID} : If PatientID in original dataset is P123, resultant PatientID will be JMSP123
PatientID={PatientID,slice,3} : If PatientID in original dataset is JMSP456, resultant PatientID will be P456
IssuerOfPatientID=pdgen-{00100010,hash}-{00100030} : Resultant IssuerOfPatientID will be pdgen suffixed with hash values of PatientName and suffixed with PatientBirthDate
00321034.00080100=ReqSrvCV01 : Resultant Code Value in RequestingServiceCodeSequence will be ReqSrvCV01
StudyDescription= / IssuerOfAccessionNumberSequence.LocalNamespaceEntityID= : Resultant dataset will have no values for StudyDescription attribute and LocalNamespaceEntityID attribute within IssuerOfAccessionNumberSequence
StudyDescription! / IssuerOfAccessionNumberSequence.LocalNamespaceEntityID! : Resultant dataset will have no attributes - StudyDescription and LocalNamespaceEntityID attribute within IssuerOfAccessionNumberSequence in it
