[Insight-users] Fwd: How to Truncate Dicom Series?

[Abayiz]

Hello,

The size of input image is [220, 250, 144], and that of ROI image is [220,225,144]. 

Any suggestion?

Thanks :)

  Hello,

Actually I found that I can handle this problem by using 
itkRegionOfInterestImageFiler, it works quite well, except it started to 
truncate the image from the opposite of the desired direction. Then I tried to 
set its index, but it gave me this error:

********************************************

Requested region is (at least partially) outside the largest possible 
region
********************************************
 

I've already used "UpdateLargestPossibleRegion()" method, here is the 
partial code:

********************************************

reader->SetFileName(argv[1]);
  
reader->Update();
  
reader->UpdateLargestPossibleRegion();

  ImageType::RegionType desiredRegion;
  
desiredRegion.SetSize(size);
  
desiredRegion.SetIndex(start);
 
  
filter->SetRegionOfInterest(desiredRegion);
  
filter->SetInput(reader->GetOutput());

  WriterType::Pointer 
writer = WriterType::New();
  writer->SetFileName ( argv[2] 
);
  writer->SetInput ( filter->GetOutput() );
  
writer->Update();
********************************************


Can anyone help? Thanks in advance.

Hi,

I 
didn't find any way to do that as you suggested. Seems like there is
no way 
to set the index for the itkImageWriter. Am I doing 
wrong?

Read the 
series and then write it truncated.
