Note that this "root" for the UIDs is organization-specific, and that the FOIA release of this software will only include data for this table for VA sites. See the DICOM Standard ( PS 3.8 Annex A for instructions on how to obtain a valid UID root.
.01owner(+)0;1FREE TEXTBThe value of this field is a string that identifies the organization to which the UID root code that is stored in this record is assigned.
1uid root(+)UID ROOT;1FREE TEXTThe value of this field is a string that represents this organization's UID root code. Values for this code must be obtained from the International Standards Organization (ISO) or from their national representative bodies (for the USA, this is ANSI). The format of an UID root code looks like a list of integer numbers, separated by periods. For VA hospitals, the value for this field will be automatically entered. Other organizations first need to obtain their "root code" from the appropriate standards organization, and then manually enter the assigned value into this field.
2last datetime uid generated1;1DATE-TIMEThis field contains the date and time that the last DICOM UID was generated.
3tick1;2NUMERICThis field is incremented every time a new DICOM UID is generated. This field is reset to one ('1') daily when a new DICOM UID is generated for the first time during the day. This field supplements LAST DATETIME UID GENERATED field (2006.15,2) to prevent duplicate DICOM UIDs within one second interval of generation requests.
