MWL thru REST - Compulsory Attributes

[Mamisoa Andriantafika]

Hi,

I'm trying to update a scheduled procedure in MWL thru Rest from dcm4chee-arc.

What are the compulsory attributes if I only want to update from "SCHEDULED" to "DEPARTED" ?

This simple json get an answer and seems to update:

{
  "00100020": {
    "vr": "LO",
    "Value": ["22879"]
  },
  "0020000D": {
    "vr": "UI",
    "Value": ["2.25.289401306701039254349950808360341823820"]
  },
  "00400100": {
    "vr": "SQ",
    "Value": [      {
        "00400020": {
          "vr": "CS",
          "Value": ["DEPARTED"]
        }
      }
    ]
  }
}

Answer:

{"00080050":{"vr":"SH","Value":["A-00000010"]},"00100020":{"vr":"LO","Value":["22879"]},"0020000D":{"vr":"UI","Value":["2.25.289401306701039254349950808360341823820"]},"00400100":{"vr":"SQ","Value":[{"00400002":{"vr":"DA","Value":["20170721"]},"00400003":{"vr":"TM","Value":["214609.246"]},"00400009":{"vr":"SH","Value":["SPS-00000015"]},"00400020":{"vr":"CS","Value":["DEPARTED"]}}]},"00401001":{"vr":"SH","Value":["RP-00000010"]}}

but I still see it in MWL ...

The POST dcm4chee-arc/aets/{aet}/rs/mwlitems request have to contain the whole MWL Item as DICOM JSON object, not just die attribute you want to update.

To change the Patient ID you will have to use another service: POST dcm4chee-arc/aets/{aet}/rs/patients/{patientID}/changeid/{priorPatientID} .

Attribute Scheduled Procedure Step Status is not in the root Dataset, but in an item of the Scheduled Procedure Step Sequence. s. http://dicom.nema.org/medical/dicom/current/output/chtml/part04/sect_K.6.html#sect_K.6.1.2.2

Just to be sure to understand.

I added the item in MWL using REST. I got a JSON response.

To update this item, I update this response and send the whole item ? I thought that I could update only using patient ID and UID for this item that are specific, and the element to be updated.

But I did not want to change the patient ID, which should indeed be change through the adequate service.
