Binocular three-dimensional perception through stereoscopic generation from rotating images

Rationale and Objectives. The authors evaluated the clinical utility and po tential applications of a binocular three-dimensional (3D) image display in diagnostic radiology. Materials and Methods. Rotating video displays of computed tomographic (CT) , magnetic resonance (MR) angiographic, and digital subtraction angiographi c (DSA) image data were used to generate stereoscopic image displays with a 3D appearance. Eight physicians viewed and scored eight skeletal and eight vascular-interventional studies with a planar display mode and a cathode r ay tube. Each physician then viewed the 3D display of the same data and ass essed the change in image findings, as well as ally corresponding changes i n level of diagnostic confidence. Results. Image findings changed in 78 (61 %) of the 128 studies after viewing the 3D displays. In 93 (73%) of all 128 studies, the interpreters reported increased confidence in their perceptio n of the findings. Results for the vascular-interventional and skeletal cases were generally v ery similar. Conclusion. Binocular 3D stereoscopic displays from rotating images were re ported to provide better image conceptualization and a higher degree of con fidence in the findings on the images.
