TubeTK/TBI Data

Image Format

Images are presented in the nii format. Each image can thus be loaded directly by any program that supports nii format, including most ITK and VTK-based applications such as Slicer.

There are two patients. For each of them there are data sets for the Acute and Chronic Stage: For each stage there are datas for 4 modalities:

1. Fluid-attenuated inversion recovery (FLAIR) data set: Fluid-attenuated inversion recovery (FLAIR) is an advanced magnetic resonance imaging sequence that reveals tissue T2 prolongation with cerebrospinal fluid suppression, allowing detection of superficial brain lesions [1].

1. Gradient Recalled Echo (GRE) data set:

We don`t have susceptibility-weighted imaging (SWI) and DTI data at the moment.
