Abstract :
There is a significant need for three-dimensional (3-D) spatial information in digital X-ray angiography (imaging of blood vessels). Availability of new, fast, c-arm systems, digital imagers and stereoscopic displays makes it possible to acquire stereoscopic X-ray angiograms. The authors develop a stereo-geometry model to explain acquisition geometry as well as basic aspects of stereoscopy, such as disparity, depth resolution and depth distortion. The authors also perform some simple experiments to verify the model. Finally, they present a set of guidelines for optimal stereoscopic acquisition
