BrainVISA

Hi,

If i compare the histogram of the corrected image and the image without bias, i think that i have a good correction.

So, thank you for your help Mr Mangin, and Mr riviere.

Hi, sorry for my late response. I've download the image from brainweb, it's an image with 0% of noise and 20% rf, i use Vipbiascorrection and take the parameters by default. I have no problem with the corrected image, and the histogram is corrected. This is the bias field i have when i take the rati...

Hi, when i have used : Aimsfileconvert -i biais.ima -o biais.img i have this type of image with mricro and spm: http://www.imagup.info/images/06/1193789355_spmbrain.png http://www.imagup.info/images/06/1193789515_mricrobrain.png When i add -t S16, it's worse (c'est pire ) :shock: http://www.imagup.i...

I had trouble to use viewer, and that why i've posted before. I' ve installed Brainvisa to use the VipBiasCorrection, i just need the image of bias field. I'm using Matlab.


Thanks

So, how can i convert the file bias.ima to visualize the bias field ? By using Aimsfileconvert or another command.

Thanks

hi, i used vipbiascorrection to an image corrupted with bias field, and i have convert the result from .ima to .img by using Aimsfileconvert. I can visualize the corrected image with mricro or brainsuite, but when i do the same thing to the file bias.ima, it's not look like bias field. Sorry for my ...

hi, i dont think that my graphic card is the problem, i can visualise the volume with other application (mricro,spm)...etc. I have downloaded the image from Brainweb, and i used vipbiascorrection and convert the images to visualise it with mricro. I dont know what is the problem when i try to visual...

Hello, Sorry for my late response! i' ve used an axial, coronal and sagittal windows to view the volume, and have only the axes. When i use brainvisa, it call anatomist when i click on the icone (eye), and i have the same problem (the axis only). i have another question, can i read the volume (.ima)...

I can read an mri volume with brainvisa (anatomist), i have only the axes!!

Sorry for my english, can i ask my question in french?
