4.2 PACS DICOM tags - FNNDSC/pfdcm GitHub Wiki

pfdcm PACS DICOM tags

Abstract

  • The series to be asked for DICOM tags must have been pulled a priori.

This page describes how to return a JSON object of DICOM tags for a given series.

Preconditions

  • A HOST_IP environment variable that denotes the IP of the host housing the service. In Linux, you can do:
export HOST_IP=$(ip route | grep -v docker | awk '{if(NF==11) print $9}')
  • Make sure that pfdcm has been started (see here for more info)
pfcon --forever --httpResponse

  • Have the following information pertaining to the remote PACS server:

    • IP
    • port
    • AETITLE
    • CALLED AETITLE

  • Set the internal values specifying the remote PACS host according to here.

  • Make sure you have a series UID from a previous call to PACS query here.

DICOM tags based on SeriesUID

Call

Data is typically retrieved on SeriesInstanceUID, and this is also used to determine the tags for a given series.

pfurl   --verb POST                             \
        --raw                                   \
        --http ${HOST_IP}:4055/api/v1/cmd       \
        --jsonwrapper 'payload'                 \
        --msg '{  
            "action": "internalDB",          
            "meta": {
                "do":  "DICOMtagsGet",
                "on" : {
                   "series_uid": "1.3.12.2.1107.5.2.32.35235.2011120607520430264805764.0.0.0"
                }
            }
        }'

Receive

A typical call returns the following (not that only DICOM tags that are type string are returned):
