The magnetic resonance angiography (MRA) can be used to examine blood vessels in key
areas of the body, including the brain. In the MRA, a powerful magnetic field, radio waves
and a computer produce the detailed images. Physicians use the procedure in brain
images mainly to detect atherosclerosis disease in the carotid artery of the neck, which
may limit blood flow to the brain and cause a stroke and identify a small aneurysm or
arteriovenous malformation inside the brain.
Multi-autostereoscopic displays provide multiple views of the same scene, rather than just
two, as in autostereoscopic systems. Each view is visible from a different range of positions
in front of the display. This allows the viewer to move left-right in front of the display and
see the correct view from any position.
The use of 3D imaging in the medical field has proven to be a benefit to doctors when
diagnosing patients. For different medical domains a stereoscopic display could be
advantageous in terms of a better spatial understanding of anatomical structures, better
perception of ambiguous anatomical structures, better performance of tasks that require
high level of dexterity, increased learning performance, and improved communication with
patients or between doctors.
In this work we describe a multi-autostereoscopic system and how to produce 3D MRA
images to be displayed with it. We show results of brain MR angiography images
discussing, how a 3D visualization can help physicians to a better diagnosis.
