Presentation Transcript

  1. Fusion of Multi-Modality Volumetric Medical Imagery Mario Aguilar and Joshua R. New Knowledge Systems Laboratory MCIS Department Jacksonville State University Jacksonville, AL 36265

  2. Outline • What is the neurophysiological motivation of the fusion architecture? • How is fusion extended to a three-dimensional operator? • How is this operator applied to volumetric data sets? • What are the results?

  12. Conclusions • Development of the 3D shunting operator is a natural extension of the 2D operator • Application of the 3D shunting operator provides better definition of image details in volumetric data sets • 3D fusion extensions developed in the context of Med-LIFE, a visualization and pattern recognition tool.
