我想用另一个 DICOM 文件替换像素数据。我使用了这段代码：

public bool ImportImage(string imageFile, string newFilePah, string oldDicomFile)
{
    try
    {
        Bitmap bitmap = new Bitmap(imageFile);
        bitmap = GetValidImage(bitmap);
        int rows, columns;
        byte[] pixels = GetPixels(bitmap, out rows, out columns);
        MemoryByteBuffer buffer = new MemoryByteBuffer(pixels);
        DicomDataset dataset = new DicomDataset();
        var df = DicomFile.Open(oldDicomFile);
        FillDataset(ref dataset, df);

        DicomTransferSyntax dicomTransfer = df.Dataset.Get<DicomTransferSyntax>(DicomTag.TransferSyntaxUID, DicomTransferSyntax.JPEGProcess14);
        dataset.AddOrUpdate(DicomTag.PhotometricInterpretation, PhotometricInterpretation.Rgb.Value);
        dataset.AddOrUpdate(DicomTag.Rows, (ushort)rows);
        dataset.AddOrUpdate(DicomTag.Columns, (ushort)columns);
        dataset.AddOrUpdate(DicomTag.BitsAllocated, (ushort)8);
        DicomPixelData pixelData = DicomPixelData.Create(dataset, true);
        pixelData.BitsStored = 8;
        pixelData.SamplesPerPixel = 3;
        pixelData.HighBit = 7;
        pixelData.PixelRepresentation = 0; …
