Real three-dimensional cardiac imaging using leading-edge holographic display.

Understanding three-dimensional cardiac anatomy is fundamental for the practice of clinical cardiology. However, if three-dimensional images are displayed on two-dimensional monitors, they fail to provide depth perception. Currently, novel technologies, including the three-dimensional printing, three-dimensional monitors/projectors, and virtual reality applications can provide real three-dimensionality with depth perception. However, their relatively high cost and limited user-friendliness prevent their wide application. We introduce novel and commercially available holographic display, which allows multiple observers to see the full-color holographic images simultaneously without any specific glasses and headgear. This leading-edge technology is immediately applicable in both educational and clinical settings.
