[Mristudio-users] New to the program

[darshan pai]

Sorry one final question,

I have Siemens data in DICOM. I read the user manual for how to convert it to an REC file, but don't know what to use for my gradient table. Does anyone know how to generate one?

Thank you again!

Hello all,

I've tried sending a couple of e-mails to the DtiStudio support staff, but they have yet to get back to me. While waiting for their reply, I was wondering if anyone in this newsletter would be able to answer my questions. Below, I have copy-pasted both my e-mails. I apologize for the length, I got a little carried away in my curiosity. 

If anyone can help, it would be greatly appreciated.

Thank you very much,

Dear Support Team,
I am writing you in reference to your program DTI Studio.
Let me begin by stating that I am very new to diffusion tensor imaging, and am
trying to use your program as a stepping stone into that field of study. For
the record, I am a research assistant in a lab that is registered on your
website (dtistudio.org) under the username slee56. 
I write to you with only a few hours of experience with the
program under my belt. The manual which you posted alongside the software is
helpful in knowing how to open files and view them. For the purposes of
learning how the program works, I downloaded the data set 01_020729_31.rec.
Initially, I was able to boot up the program and load the data set via file
-> dtimapping. Using the gradient posted next to the data set on your demo
data database, and leaving all other settings as they were, I was able to bring
up the axial, sagittal, coronal, and 3-d views of the .rec file. Next, under
the dtimap tab, I clicked "tensor, color map, etc." to come up with the
different maps. Once this was completed, I was able to view the different maps,
but this is where my problems began. 
As I stated earlier, I am very new to this field, and thus
am at a loss when it comes to actually interpreting
the data. 
For this reason, I am contacting you to ask whether you have
some documentation on how to "read" all the various DTI maps that this program
is capable of creating, along with a glossary which explains every term used in
the program. For me to create maps and not know what I am looking at presents a
problem that, hopefully, you can help me with. I have looked through the user
manual that is on your webpage, and while it is very helpful in utilizing the
program itself, it does not help me interpret the images. For example, I am
completely unaware how to find within what area of the brain the diffusion is
higher or lower than normal, or even know what normal is for that matter. 
Finally, I was wondering if you could tell me that after
creating the "tensor, color maps etc," where I can view the data this
calculates, and what those figures mean. 
Also, just as a side note, under the dtimap whenever I click
any of the buttons under "calculation," 40% of the time it causes the program
to severely stall and/or crash altogether.
I really appreciate your help in this matter, and hope to
soon become knowledgeable in this area with your aid. So if there is some
documentation explaining every single in and out of what DTI images are, show,
and help with, it would be incredibly useful to me. 
 
Thank you for your time,

Dear Support Team,
This is the second e-mail that I am writing
to you, and not being sure whether or not my first e-mail reached you,
I've attached it below. This e-mail, however, is in reference to
converting DICOM images to REC images. I was able to follow the user
manual to perform the actual conversion, however, when I load the newly
created REC, I am unable to perform any of the mapping functions. Does
anyone know why this is happening?
Thank you for your time, I hope to hear from you soon in regards to this e-mail and the one attached below.
