API Documentation

The API documentation for the core library (represented by fo-dicom.Desktop) and the log4net, NLog and Serilog connectors is available here.

Usage Notes

Image rendering configuration

Out-of-the-box, fo-dicom for .NET defaults to Windows Forms-style image rendering. To switch to WPF-style image rendering, call:

ImageManager.SetImplementation(WPFImageManager.Instance);

Logging configuration

By default, logging defaults to the no-op NullLogerManager. On .NET, several log managers are available and can be enabled like this:

LogManager.SetImplementation(ConsoleLogManager.Instance);  // or ...
LogManager.SetImplementation(NLogManager.Instance);        // or ...

On Universal Windows Platform, Xamarin iOS, Xamarin Android and Mono there is only one operational log manager available, namely MetroLogManager.Instance.

Cross-platform development

To facilitate cross-platform development, the core library is strong name signed and denoted Dicom.Core.dll on all platforms. From an assembly reference point-of-view this convention makes the core assemblies mutually replaceable. It is thus possible to develop a Portable Class Library that depends on the PCL Dicom.Core assembly, and when the developed Portable Class Library is used in a platform-specific application, the PCL Dicom.Core assembly can be replaced with the platform-specific Dicom.Core assembly without needing to re-build anything. fo-dicom.Json and fo-dicom.MetroLog are examples of portable class libraries that depend on the PCL Dicom.Core.dll.

The assembly naming convention is often referred to as the bait-and-switch trick. The fo-dicom package supports the bait-and-switch trick by automatically selecting the best suited Dicom.Core assembly depending on the targeted platform of the development project upon download from NuGet.

Sample applications

There are a number of simple sample applications that use fo-dicom available in separate repository here. These also include the samples that were previously included in the Examples sub-folder of the VS solutions.

Examples

File Operations

var file = DicomFile.Open(@"test.dcm");             // Alt 1
var file = await DicomFile.OpenAsync(@"test.dcm");  // Alt 2

var patientid = file.Dataset.Get<string>(DicomTag.PatientID);

file.Dataset.AddOrUpdate(DicomTag.PatientName, "DOE^JOHN");

// creates a new instance of DicomFile
var newFile = file.Clone(DicomTransferSyntax.JPEGProcess14SV1);

file.Save(@"output.dcm");             // Alt 1
await file.SaveAsync(@"output.dcm");  // Alt 2

Render Image to JPEG

var image = new DicomImage(@"test.dcm");
image.RenderImage().AsBitmap().Save(@"test.jpg");                     // Windows Forms
image.RenderImage().AsUIImage().AsJPEG().Save(@"test.jpg", true);     // iOS

C-Store SCU

var client = new DicomClient("127.0.0.1", 12345, false, "SCU", "ANY-SCP");
await client.AddRequestAsync(new DicomCStoreRequest(@"test.dcm"));
await client.SendAsync();

C-Echo SCU/SCP

var server = new DicomServer<DicomCEchoProvider>(12345);

var client = new DicomClient("127.0.0.1", 12345, false, "SCU", "ANY-SCP");
client.NegotiateAsyncOps();
for (int i = 0; i < 10; i++)
    await client.AddRequestAsync(new DicomCEchoRequest());
await client.SendAsync();

C-Find SCU

var cfind = DicomCFindRequest.CreateStudyQuery(patientId: "12345");
cfind.OnResponseReceived = (DicomCFindRequest rq, DicomCFindResponse rp) => {
	Console.WriteLine("Study UID: {0}", rp.Dataset.Get<string>(DicomTag.StudyInstanceUID));
};

var client = new DicomClient("127.0.0.1", 11112, false, "SCU-AE", "SCP-AE");
await client.AddRequestAsync(cfind);
await client.SendAsync();

C-Move SCU

var cmove = new DicomCMoveRequest("DEST-AE", studyInstanceUid);

var client = new DicomClient("127.0.0.1", 11112, false, "SCU-AE", "SCP-AE");
await client.AddRequestAsync(cmove);
await client.SendAsync();

N-Action SCU

// It is better to increase 'associationLingerTimeoutInMs' default is 50 ms, which may not be
// be sufficient
var dicomClient = new Dicom.Network.Client.DicomClient("127.0.0.1", 12345, false, "SCU-AE", "SCP-AE",
DicomClientDefaults.DefaultAssociationRequestTimeoutInMs, DicomClientDefaults.DefaultAssociationReleaseTimeoutInMs,5000);
var txnUid = DicomUIDGenerator.GenerateDerivedFromUUID().UID;
var nActionDicomDataSet = new DicomDataset
{
    { DicomTag.TransactionUID,  txnUid }
};
var dicomRefSopSequence = new DicomSequence(DicomTag.ReferencedSOPSequence);
var seqItem = new DicomDataset()
{
    { DicomTag.ReferencedSOPClassUID, "1.2.840.10008.5.1.4.1.1.1" },
    { DicomTag.ReferencedSOPInstanceUID, "1.3.46.670589.30.2273540226.4.54" }
};
dicomRefSopSequence.Items.Add(seqItem);
nActionDicomDataSet.Add(dicomRefSopSequence);
var nActionRequest = new DicomNActionRequest(DicomUID.StorageCommitmentPushModelSOPClass,
                DicomUID.StorageCommitmentPushModelSOPInstance, 1)
{
    Dataset = nActionDicomDataSet,
    OnResponseReceived = (DicomNActionRequest request, DicomNActionResponse response) => 
    {
        Console.WriteLine("NActionResponseHandler, response status:{0}", response.Status);
    },
};
await dicomClient.AddRequestAsync(nActionRequest);
dicomClient.OnNEventReportRequest = OnNEventReportRequest;
await dicomClient.SendAsync();

private static Task<DicomNEventReportResponse> OnNEventReportRequest(DicomNEventReportRequest request)
{
    var refSopSequence = request.Dataset.GetSequence(DicomTag.ReferencedSOPSequence);
    foreach(var item in refSopSequence.Items)
    {
        Console.WriteLine("SOP Class UID: {0}", item.GetString(DicomTag.ReferencedSOPClassUID));
        Console.WriteLine("SOP Instance UID: {0}", item.GetString(DicomTag.ReferencedSOPInstanceUID));
    }
    return Task.FromResult(new DicomNEventReportResponse(request, DicomStatus.Success));
}
