BrainWeb: About the Simulated Brain Database
The pre-generated Simulated Brain Database (SBD) was produced using
the following parameters:
- pulse sequence:
- as in the ICBM {T1,T2,PD} template of custom simulations.
- noise:
- the reference tissue for the noise computation was: White Matter for T1, and CSF for T2 and PD images.
- INU (intensity non-uniformity):
- the field A was used for T1 images, field B for T2 images, and field C for PD images.
Note that you can obtain images with any other combination of parameters by using the custom simulations feature.
Intensity non-uniformity fields:
You can download the inhomogeneity
fields used to simulate these MR images. There are three fields
available: field A,
field B,field C.
These files are the 20% INU version. For other INU levels, these
fields are rescaled linearly to provide alternate inhomogeneity
percentages.
