Using high resolution displays for high\ud resolution cardiac data

By C. Goodyer, J. Hodrien, J. Wood, P. Kohl and K.W. Brodlie


The ability to perform fast, accurate, high resolution visualization is fundamental\ud to improving our understanding of anatomical data. As the volumes of data\ud increase from improvements in scanning technology, the methods applied to rendering\ud and visualization must evolve. In this paper we address the interactive display of\ud data from high resolution MRI scanning of a rabbit heart and subsequent histological\ud imaging. We describe a visualization environment involving a tiled LCD panel\ud display wall and associated software which provide an interactive and intuitive user\ud interface.\ud The oView software is an OpenGL application which is written for the VRJuggler\ud environment. This environment abstracts displays and devices away from the\ud application itself, aiding portability between different systems, from desktop PCs to\ud multi-tiled display walls. Portability between display walls has been demonstrated\ud through its use on walls at both Leeds and Oxford Universities. We discuss important\ud factors to be considered for interactive 2D display of large 3D datasets,\ud including the use of intuitive input devices and level of detail aspects
