[Insight-users] Dicom slice position

[Mathieu Malaterre]

Jolinda,

	I have a question about your program MRI convert. I used it to convert 
my set of DICOM images. And as you said it takes into account the Image 
Position Patient. Here is the value I extracted from my files:

Patient		 	[ -199.506987\-34.042491\255.448394]

So acquisition axe is Y (Y spacing is 1.5), but there is also a Z variation.

So my questions is:
- Does MRIConvert takes this Z variation also into account ?
- If yes how come the result is still 512*512 ? There should be some 
black/white area

          512

In those two areas you don't know the value of the pixel, right ?

Thanks for putting some light on it.

Ps: When will the linux version be available ?
