Converting GDCM Image to Java BufferedImage

问题

I am using GDCM to read in DICOM images. Is there an easy way to read in a dicom file with GDCM, and then convert it to a Java BufferedImage? So far I have the following

String filename = "C:\\test.dcm";
    gdcm.ImageReader reader = new gdcm.ImageReader();
    reader.SetFileName(filename);
    reader.Read();
    gdcm.Image image = reader.GetImage();
    BufferedImage bufferedImage = new BufferedImage((int)image.GetRows(, (int)image.GetColumns(), BufferedImage.TYPE_USHORT_GRAY);
    // How do I populate bufferedImage?;

Can anyone tell me if I'm on the right track and how to complete this example.

Thanks

You can retrieve the raw buffer of pixel using:

  byte[] str1 = new byte[ image.GetBufferLength()];
  image.GetBuffer( str1 );

See full example at:

or
