DICOMweb Go

Introduction

A DICOMweb client for Golang.

There are plenty of packages that allow you to read DICOM files in Go whereas not much for communicating with DICOM server.

Currently there are DICOM servers such as dcm4chee, Orthanc, etc., that support read/write DICOM by HTTP protocol, known as DICOMweb.

This package provides a simple DICOMweb client that allows you to query DICOM info (QIDO), retrieve DICOM files (WADO), and store DICOM files (STOW).

Documentation

• Dicomweb : https://www.dicomstandard.org/dicomweb

Getting Started

Installation

go get github.com/Szubie/dicomweb-go/dicomweb

Requirements

• Go 1.12+

Quick Examples

note: for demonstration, the endpoint is set to a dcm4chee server hosted by dcmjs.org. Change it to your DICOM server instead.

Query all study

client := dicomweb.NewClient("https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs")

qido := dicomweb.QIDORequest{
    Type: dicomweb.Study,
}
resp, err := client.Query(qido)
if err != nil {
    log.Fatalf("faild to query: %v", err)
}

Query all series under specific study

client := dicomweb.NewClient(dicomweb.ClientOption{
    QIDOEndpoint: "https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs",
    WADOEndpoint: "https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs",
    STOWEndpoint: "https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs",
})

    Type:              dicomweb.Series,

}
resp, err := client.Query(qido)
if err != nil {
    log.Fatalf("faild to query: %v", err)

        log.Fatalf("faild to retrieve: %v", err)
    }

    b, err := ioutil.ReadFile(fname)
    if err != nil {
        log.Fatal(err)
    }
    parts = append(parts, b)
}

stow := dicomweb.STOWRequest{
    StudyInstanceUID: "1.2.840.113820.0.20200429.174041.3",
    Parts:            parts,
