Learning Objectives: 1. Load PET and CT images, display fused images, and select/switch display modes. 2. Use four modes of fusion display. 3. Understand the application of this package to clinical practice.
Abstract (summary): We have developed an open-source application specifically for PET/CT image display that is both fast and platform-independent. There are several high-quality PET/CT display systems available, but these are not open-source and/or platform independent. The combination of PET and CT images offer both accurate and sensitive cancer information with respect to detailed patient anatomy. The application (FusionViewer) facilitates efficient visualization and analysis of PET/CT studies in different modes (linked cursor display, alpha-blend mode, checkerboard mode and split window mode). Localization is preserved when switching between display modes. FusionViewer is implemented in Java and linked to the Java OpenGL (JOGL) library and Insight segmentation and registration toolkit (ITK) library, which make it both fast and a cross-platform application. Its graphical user interface makes it easy to be used by physicians, radiologists, and research scientists. Several analysis and display tools are already available (navigator, zoom, pan, screen snapshot, ROI, and line measure tool; alpha-blending, checkerboard display, and split window display) There are also multiple color tables and CT W/L presets. The application has been validated with clinical PET and CT images and has been tested on Windows XP and Mac OS X. The source code is fully documented and available at sourceforge.net. This presentation will demonstrate the steps of acquiring data, displaying fused images and selecting/switching display modes.
