Welcome to FusionViewer


FusionViewer is an open source medical image display package developed by Insightful and the Imaging Research Laboratory at University of Washington. It is designed to improve the physician's ability to interpret the results of combined positron emission tomography (PET) and computed tomography (CT) studies. This software is a display application for facilitating and improving visualization. The effective display of the fused data permits easy viewing of the anatomical information provided by the CT images while simultaneously displaying the functional data provided by PET.

Getting Started

The best starting point is to try FusionViewer Demo. Please view user's guide for more information.

Important Notice! Current FusionViewer executable is Windows Vista compatible. But due to the fact that DirectX is chosen by default on Vista system with an ATI graphic card while we are using OpenGL to perform the rendering, there is a bug which disables the view mode switching.

Solution: Please update the Video card driver. One of the possible solutions is to start a new application window if you want to display the images with different layout. We are working on this issue and hope to resolve it in near future.
