Study evaluates stack mode viewing techniques
by Douglas Page
In the absence of satisfactory 3D viewers, most volumetric medical data is currently viewed as stacks of 2D slices. Yet little research has been conducted on stack mode viewing techniques.
A recent study from Canada evaluated three interaction techniques for scrolling stack mode displays of volumetric data:
* Two techniques used a scroll-wheel mouse.
* One used only the wheel, while another used a click-and-drag technique for fast scrolling, using the wheel only for fine-tuning adjustments.
* The third technique used a new device called the Shuttle Xpress jog wheel.
"The paper addresses an underutilized research area of how new technology, in this case the contour shuttle device, can improve radiologist workflow during the typical task of viewing potentially hundreds of 2D CT and MR image slices using cine mode image navigation," said M. Stella Atkins, Ph.D., of the School of Computing Science, Simon Fraser University.
