[Mristudio-users] DTIstudio on Vista potential problem

[susumu]

Hi Jim,

 

? Can I expect problems 

   on any listed vendor for any specific MRI version 

   on a XP laptop?  vista laptop?

 

> DtiStudio should be able to process all these data. Vista laptop should be
fine. The only issue could be memory. If you are using a 32-bit XP or Vista
and/or only 1GB memory, it happens frequently.

 

I have a vista laptop which I could use but not yet loaded,   

   for any specific MRI version?

 

> No, XP and Vista use the same version of DtiStudio. There are 32 and
64-bit versions.

 

? Can anyone send me Philips gradient files 

  (should be 6 direction) or are they in the rec files?

 

No the gradient orientation is not specified in the Philips REC/PAR file.
Jon Farrell has a nice web-based software to make a gradient table for
Philips scanner based on imaging parameters and the version of the operating
system. Jon, could you send us the URL of your software?

 

I am attempting to run without success an Indiana site study 

0008,0020  Study Date: 20040625

0008,0070  Manufacturer: GE MEDICAL SYSTEMS

0008,103E  Series Description: dti scheme9 

0018,1020  Software Versions(s): 09 

without imbedded gradient vectors and using Bessar normalized gradients.

It loads but I get no FA map.  

on a 3 yr old laptop and 2  2 yr old PCs installed in an MRI research room. 

 

You need to get a correct gradient table because it is not always available
through data headers.

 

memory is OK, 

Any graphics card  requirements? 

 

No, DtiStudio is not graphics-heavy, but depending on the size of your data,
you need a decent amount of RAM.
