fMRI: Activation Map Visualization

With MedINRIA, you can visualize your fMRI study results at the same time as you visualize your DTI results. Indeed, you can import an activation map assuming it has the same dimensions as the current displayed image. For that click on the ``Open activation map'' button. It will display colored activation regions in the volume (see Fig. 3.18). The activation regions are colored from red to purple and going through the rainbow colors.

Figure 3.18: This figure shows an activation map displayed in a T1 image. On the left is shown a coronal 2D view of a T1 image with the activation regions colorized from red to purple. A Volume Rendering is shown on the right, with a red extracted fiber bundle.

Note that if you change volume the activation map will disappear, you will have to load it again. You can also change the color mapping by moving the activation map sliders. First slider controls the minimum level of activation to be displayed, while the second one controls the color saturation.
