Brain Tutor HD on iPad - It's a Kind of Magic

When Steve Jobs introduced the iPad to the world, he called it a "magic" device. And indeed, playing, learning and working with it feels very intuitive. Especially its relatively large screen evokes the feeling that one works with a serious mobile computing platform and the multi-touch interface is even more impressive than on a 3-4 inch gesture-driven smartphone screen. When I decided to develop a version of Brain Tutor for the iPad, I immediately realized that it had to exploit the larger screen for more efficient navigation and for better visualizations of brain slices...

Automatic Intensity Inhomogeneity Correction

Intensity inhomogeneities in MR images can substantially reduce the accuracy of segmentation and registration. Despite advances of correcting spatial intensity inhomogeneities, the advent of multichannel phased array coils and 7T+ scanners have increased (again) the importance of this problem for post-scan processing. Since many years, BrainVoyager includes a powerful intensity inhomogeneity correction (IIHC) tool that is based on a “surface fitting” approach to voxels preliminary labelled as white matter. This tool required, however, that...

Towards 'Minority Report Interfaces': BV Viewer Reloaded

The movie “Minority Report” was very visionary in 2002; people remember not only the exciting “pre-crime murder prevention” plot, but also the way how John Anderton (Tom Cruise) interacted with the computer: Images were retrieved, moved, rotated and scaled by simple hand gestures. While hardware for such distant gesture control is not yet widely available (this might change when Microsofts “Natal” system ships), touch-enabled input devices have become very popular in the last years. When Apple announced the iPad two weeks ago...
