Write(Stream,String,DicomDataSet) Method

In This Topic

Writes dataset to a system IO stream object with specified transfer syntax and meta header

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Sub Write( _
   ByVal Stream As System.IO.Stream, _
   ByVal TransferSyntax As System.String, _
   ByVal MetaHeader As DicomDataSet _
)

public void Write( 
   System.IO.Stream Stream,
   System.string TransferSyntax,
   DicomDataSet MetaHeader
)

Parameters

Stream: The Stream to which to write.
TransferSyntax: Specifies the full UID of the transfer syntax with which the data is to be saved when Part 10 format is used. If omitted, the little-endian explicit VR transfer syntax is used.
MetaHeader: The customized MetaHeader (only Group 2 Elements)

Remarks

The file may subsequently be read by the Read method or by other DICOM software.

The provided meta header should only contain group 2 elements.

Example

DicomDataSet ds = new DicomDataSet();
DicomDataSet metaHeader = new DicomDataSet();
string transferSyntax = TransferSyntaxes.ExplicitVRLittleEndian;
                    
string pixelTransferSyntax = TransferSyntaxes.ExplicitVRLittleEndian;
ds.Add(Keyword.SamplesPerPixel, 1);
ds.Add(Keyword.PhotometricInterpretation, "MONOCHROME2");
ds.Add(Keyword.Rows, 512);
ds.Add(Keyword.Columns, 512);
ds.Add(Keyword.PixelSpacing, new float[] { 0.684f, 0.684f });
ds.Add(Keyword.BitsAllocated, 16);
ds.Add(Keyword.BitsStored, 12);
ds.Add(Keyword.HighBit, 11);
ds.Add(Keyword.PixelRepresentation, 0);
ds.Add(Keyword.WindowCenter, new int[] { 35, 50 });
ds.Add(Keyword.WindowWidth, new int[] { 350, 150 });
ds.Add(Keyword.RescaleIntercept, -1200);
ds.Add(Keyword.RescaleSlope, 1);
ds.SetPixelData(pixelTransferSyntax, getData);
                    
metaHeader.Add(Keyword.MediaStorageSOPClassUID, SOPClasses.CT); // CT Image Storage
metaHeader.Add(Keyword.MediaStorageSOPInstanceUID, DicomGlobal.NewUID());
metaHeader.Add(Keyword.TransferSyntaxUID, transferSyntax);
metaHeader.Add(Keyword.ImplementationClassUID, DicomGlobal.ImplementationUID);
metaHeader.Add(Keyword.ImplementationVersionName, DicomGlobal.ImplementationName);
  
using (FileStream fs = new FileStream("Output_Dataset.dcm", FileMode.Create, FileAccess.Write))
{
    ds.Write(fs, transferSyntax, metaHeader);
}
                    
// Method
private Stream getData(int arg)
{
    return new FileStream("pixel.data", FileMode.Open, FileAccess.Read, FileShare.Read);
}

Requirements

Target Platforms: .NET CLR 4.8 or higher
