Data coercion forces defined value into specific fields that the
modality may not have included in the object. The data coercion
engine supports three modes: 1) overwrite a DICOM attribute with a defined
value; 2) assign one DICOM attribute value to another DICOM attribute; and
3) parse the contents of one DICOM attribute and assign part of it to
another DICOM attribute. At this time, coercion works for DICOM
alpha-numeric attributes only.
Coercion rules get assigned to a specific registered device, and are
applied to all DICOM C-STORE messages that arrive from that device.
Multiple rules can exist for a single device, and they are applied in the
defined sequence. For example, if the admin wants to swap two
values, he must define a three-step process: assign the value from one
attribute to a temporary attribute, copy the value from the second
attribute to the first attribute, and then copy the value in the temporary
attribute to the second attribute.
To define coercion rules, go to the Devices page and click on the edit
button of
the device in the Devices table. At the bottom of the DICOM Services
page, the
format of each rule is explained in the legend. If you need the DICOM tag for a particular attribute, select
it from the pull-down menu and click on Add Tag. If the attribute is
not available, enter it directly into the text box. Complete the
rule by typing the rest of the command. When you have completed all
the rules, click on Save. Note that these rules do not propagate
between linked servers. |
