Because the original web site at Massachusetts General Hospital's Center for Morphometric Analysis is no longer working, the Internet Brain Segmentation Repository is now being released right here on NITRC.  That web site was created in 1996 and has functioned faithfully for 17 years!  The original site is still up and contains some additional information, but new access to the data is no longer available.

There are two data sets that have been very popular: the "20 Normal" subjects and the newer "IBSR_V2.0" subjects.  Up until recently, these were the best and most comprehensive, manually labeled MRI brain scans publicly available.  Data from the IBSR has been used in publications more than 107 times (I stopped counting in early 2009).

Long live the new IBSR!

Hi Andy:

This is awesome, thanks!

This may be a good time to ask - I made for myself NIFTI images (in correct orientation) and fairly nice (I like to think) skull strippings for the 18 parcellated cases a while back.

Might there be any interest on your part in putting these here also, so others can get them if they want to? (I'd still have to dig them up again, though).

Best,

Hi Torsten,

Yes. that would be excellent!  I think many would benefit from having the old data in a modern format, and skull stripped too.

Thanks again, Torsten!   The IBSR_V2.0 scans, now skull-stripped and in NIfTI format are uploading as I type this.

Hi

I am looking for: IBSR volume 110_3, slice 128:30:166
is there this IBSR here?

Which Download file are you talking about?

Andy.

Hi

I downloaded the IBSR from here(stripped). how can i use it i mean when i open it there is an error: unknown format.
I searched and found MIPAV software,i wanted to be sure that with this software i can use this pack  or no.

Hello, 
I am using original 20 normal image dataset provided here. In that segmentation and 8bit format dataset are provided in '.buchar' format can anyone please suggest me how to read them. It will be really helpful.

Regards, 
Raghav

Hi Vahideh,

Sorry for the slow response.

Look at the README files for the scans you are trying to open.  Some of them are "raw" (have no header information) so you have to tell MIPAV how the number of columns, rows, slices, voxel size, number of bytes, etc.

Here is a description of the ".img" files.

Andy.

Hi Raghav,

Sorry for the slow response.

The '.buchar' format means they are 8-bit "raw" format.  You need to tell the software you are opening them with that, along with the number of columns, rows, slices, and voxel resolutions.  That information can be found in the ".hdr" file for each scan and/or in the README file.

Andy.
