Article Synopsis
- A new autostereoscopic display was developed to visualize static 3D models from intracranial time-of-flight MR angiography and compared against conventional 2D displays.
- In a study involving three neuroradiologists examining 3D models of intracranial arteries, a significantly higher percentage of arterial markings were correctly identified using the autostereoscopic display.
- The findings suggest that autostereoscopic displays enhance the visualization of intracranial arteries, improving identification rates compared to traditional 2D displays.

Background: The detection of small nodules in pulmonary multidetector computed tomography (MDCT) data sets is challenging, and there is a need for visualization techniques that can improve reader sensitivity and efficiency. We have developed a subvolume rendering technique ("Softslice") with nonlinear, symmetrical modulation of the relative signal intensity along the viewing direction. Our hypothesis was that this technique might provide an advantageous visual differentiation between nodules and overlapping vessels in pulmonary MDCT subvolumes.
