[Mristudio-users] 3D volume of the whole brain

[Hua KG]

Hi, Judy

 

You may try to use mean DWI image generated from DTIStudio. B0 image is not exactly mean DWI image. 

 

If you still can't find appropriate threshold, you may try to toggle on/off the byte order. The s/w only works with raw images so far.

 

Thanks! Let me know if you have further questions!

> I downloaded the s/w and tried to load a mean DWI (Bo) image that is generated from DTIstudio. It did not work. In the VTK output, it is giving errors in reading the file. I tried saving the mean DW images in all the 3 formats mentioned: raw, analyze and NRD. But the DTI3DMRI was not able to take any. Also there was an error message that popped mentioning about the threshold being set high. 30 was the default, but I set it to '0'. But it still kept taking 30.
