- W4206951692 abstract "To investigate a virtual reality imaging system in terms of visualization accuracy and appropriate orientation when displaying cardiac anatomy, we used an ex vivo model enabling direct comparison between reconstructed 3-dimensional visualization of intracardiac structures and real-time visual images.We established a systole-diastole platform using a swine heart activated by an external mechanical pump and reservoir, allowing simultaneous acquisition of endoscopic visual and computed tomography images of the aortic valve. Virtual images were processed from computed tomography data using 3-dimensional software (the Vesalius 3D suite; PS Medtech, Amsterdam, Netherlands) and compared with visual images seen through a fiberoptic scope.An endoscope gave a fine view of the aortic valve, whereas the virtual images elucidated the valve structures. Superimposition of the images from the 2 different modalities showed the virtual reality images precisely matching the visual images in both systole and diastole, confirming the validity of this virtual reality application.In view of this demonstrated fidelity of virtual imaging, this technology may be of sufficiently high quality to be considered a gold standard for cardiac anatomy." @default.
