[Insight-users] Slice extraction in multiple axis

[Luis Ibanez]

Hi Wagner,

Two Questions:


1) What fileformat did you used for saving the slice images ?

2) What image viewer (software) are you using to display these
    resulting slice image files ?



It is very likely that:


A) you choose to save the image in a file format that does not
    support pixel spacing (e.g. PNG, JPEG...)

and/or

B) You are using an image viewer that does not take pixel
    spacing into account.


As a verification, in your slice extraction code you can
add the call:


   extractFilter->Update();
   std::cout << "Input volume characteristics" << std::endl;
   extractFilter->GetInput()->Print( std::cout );
   std::cout << "Output slice characteristics" << std::endl;
   extractFilter->GetOutput()->Print( std::cout );


and with this output you should be able to verify if the
original spacing of the image was respected on every slice.


Please let us know your answers to questions (1) and (2).


    Thanks


        Luis
