Question

我已使用GDCM库成功将 8位图像写为DICOM文件。现在我尝试将 16位图像写为DICOM文件。这是我的代码。任何人都可以指出我缺少什么或应该做些什么。

static public void CreateSmallDICOMShort(string fileName, short [] buffer, uint[] dim)
  {
      using (var writer = new gdcm.PixmapWriter())
      {
          gdcm.Pixmap img = writer.GetImage();
          img.SetNumberOfDimensions(3);
          var pixelFormat = new PixelFormat();
          pixelFormat.SetScalarType(PixelFormat.ScalarType.UINT16);
          img.SetDimension(0, dim[0]);
          img.SetDimension(1, dim[1]);
          img.SetDimension(2, 1); // fake a 3d volume
          img.SetPixelFormat(pixelFormat);
          PhotometricInterpretation pi = new PhotometricInterpretation(PhotometricInterpretation.PIType.MONOCHROME1);
          img.SetPhotometricInterpretation(pi);
          gdcm.DataElement pixeldata = new gdcm.DataElement(new gdcm.Tag(0x7fe0, 0x0010));
          //byte[] buffer = new byte[512 * 512 * 2];
          pixeldata.SetArray(buffer,(uint)buffer.Length);
          img.SetDataElement(pixeldata);

          gdcm.File file = writer.GetFile();
          gdcm.DataSet ds = file.GetDataSet();
          gdcm.DataElement ms = new gdcm.DataElement(new gdcm.Tag(0x0008, 0x0016));
          string mediastorage = "1.2.840.10008.5.1.4.1.1.7.2"; // Multi-frame Grayscale Byte Secondary Capture Image Storage
          byte[] val = StrToByteArray(mediastorage);
          ms.SetByteValue(val, new gdcm.VL((uint)val.Length));
          ds.Insert(ms);

          writer.SetFileName(fileName);
          writer.Write();
      }
  }

Answer 1

您需要使用其他SetArray()功能。您正在为图像缓冲区传递一个8位数据数组。只需传递一个16位数组。例如：

unsigned short[] buffer = new unsigned short[512 * 512];
pixeldata.SetArray(buffer,(uint)buffer.Length);

Answer 2

您是否尝试过设置BitsAllocated，HighBit和BitsStored标签？
