The objective of this study was to establish the accuracy of an holographic display approach for detection of stenoses in coronary arteries. The rationale for using an holographic display approach is that multiple angles of view of the coronary arteriogram are provided by a single 'x-ray'-like film, backlit by a special light box. This should be more convenient in that the viewer does not have to page back and forth through a cine angiogram to obtain the multiple angles of view. The method used to test this technique involved viewing 100 3D coronary angiograms. These images were generated from the 3D angiographic images of nine normal coronary arterial trees generated with the Dynamic Spatial Reconstructor (DSR) fast CT scanner. Using our image processing programs, the image of the coronary artery lumen was locally 'narrowed' by an amount and length and at a location determined by a random look-up table. Two independent, blinded, experienced angiographers viewed the holographic displays of these angiograms and recorded their confidence about the presence, location, and severity of the stenoses. This procedure evaluates the sensitivity and specificity of the detection of coronary artery stenoses as a function of the severity, size, and location along the arteries.
