DCM文件未正确压缩。 [英] DCM file not compressing properly.

问题描述

我正在使用GDCM工具压缩dicom图像，但图像未正确压缩。我发布了示例代码。



我尝试过：



我的代码如下：

string inputFileNamepath = @G：\Test \ Test_07_06_2016 \Source\CT-MONO2-16-ankle.dcm;

string outputFileNamepath = @G：\Test \ Test_07_06_2016 \ Source1 \\\\\\\\\\\\\\\\\\\\\\\,,,,,, file = new FileInfo（@G：\Test \ Test_07_06_2016 \ Source \ BU001015MN-166-CL-001V01_2005101414120923_1_1.dcm）;



字符串扩展名= Path.GetExtension（inputFileNamepath）;

inputFileName = Path.GetFileName（inputFileNamepath）;



outputFileName = Path.GetFileName（outputFileNamepath）;



试试

{

gdcm.ImageReader reader = new ImageReader（）;

reader.SetFileName（inputFileNamepath）;

if（！reader.Read（））

{

//System.Console.WriteLine(\"Could not read：+ filename） ;

MessageBox.Show（错误）;

返回;

}





gdcm.File file = reader.GetFile（）;



gdcm.DataSet ds = file.GetDataSet（）;

gdcm.Image image = reader.GetImage（）;



ImageChangeTransferSyntax change = new ImageChangeTransferSyntax（）;

TransferSyntax targets = new TransferSyntax（TransferSyntax.TSType.JPEG2000Lossless）;

change.SetTransferSyntax（targets）;



JPEGCodec codec = new JPEGCodec（ ）;



if（！codec.CanCode（targets））

{

/ / MessageBox.Show（WrongData）;

//返回;

}

codec.SetLossless（false）;

codec.SetQuality（90）; //质量差！

change.SetUserCodec（codec）; //指定用于ImageChangeTransferSyntax的编解码器



change.SetInput（图片）;



bool b = change.Change（）;



if（！b）

{

MessageBox.Show（ 无法更改Ttansfer语法）;

//返回;

}



ImageWriter writer = new ImageWriter（）;

writer.SetImage（（gdcm.Image）change.GetOutput（））;

writer.SetFile（reader.GetFile（））;

writer.SetFileName（outputFileNamepath）;



if（！writer.Write（））

{

MessageBox.Show（无法写）;

}









}

catch（Exception ex ）

{



}

I am compressing dicom images using GDCM Tool but image is not compressed properly. I am Posting the Sample Code.

What I have tried:

My code is as follow:
string inputFileNamepath = @"G:\Test\Test_07_06_2016\Source\CT-MONO2-16-ankle.dcm";
string outputFileNamepath = @"G:\Test\Test_07_06_2016\Source1\CT-MONO2-16-ankle.dcm";

//FileInfo file = new FileInfo(@"G:\Test\Test_07_06_2016\Source\BU001015MN-166-CL-001V01_2005101414120923_1_1.dcm");

string extension = Path.GetExtension(inputFileNamepath);
inputFileName = Path.GetFileName(inputFileNamepath);

outputFileName = Path.GetFileName(outputFileNamepath);

try
{
gdcm.ImageReader reader = new ImageReader();
reader.SetFileName(inputFileNamepath);
if (!reader.Read())
{
//System.Console.WriteLine("Could not read: " + filename);
MessageBox.Show("Error ");
return;
}


gdcm.File file = reader.GetFile();

gdcm.DataSet ds = file.GetDataSet();
gdcm.Image image = reader.GetImage();

ImageChangeTransferSyntax change = new ImageChangeTransferSyntax();
TransferSyntax targets = new TransferSyntax(TransferSyntax.TSType.JPEG2000Lossless);
change.SetTransferSyntax(targets);

JPEGCodec codec = new JPEGCodec();

if(!codec.CanCode(targets))
{
// MessageBox.Show("WrongData");
//return;
}
codec.SetLossless(false);
codec.SetQuality(90); // poor quality !
change.SetUserCodec(codec); // specify the codec to use to the ImageChangeTransferSyntax

change.SetInput(image);

bool b = change.Change();

if (!b)
{
MessageBox.Show("Can not change Ttansfer Syntax");
//return;
}

ImageWriter writer = new ImageWriter();
writer.SetImage((gdcm.Image)change.GetOutput());
writer.SetFile(reader.GetFile());
writer.SetFileName(outputFileNamepath);

if (!writer.Write())
{
MessageBox.Show("Could not write");
}




}
catch (Exception ex)
{

}

推荐答案

你将拥有与编写您正在使用的GDCM工具的人交谈。您发布的代码似乎没有问题。

You're going to have to talk to the people who wrote the "GDCM tool" you're using. There doesn't appear to be a problem with the code you posted.
