* Some modification were introduced in the volume reconstruction in order to be compatible with the new version of the OpenIGTLinkRemote module.
* Volume reconstruction is not in real time anymore. Now, it is necessary to acquire the whole sequence before. This is in order to have a good grid for the volume reconstruction.
* Now it is possible to see the reconstructed volume slices in the Navigation step just clicking the show volume button.
* Now you hear a status sound when you acquire a tracker point position for registration.
