Tracer

Tracer is a Java application that allows images to be displayed in three dimensions. The tool allows anatomic structures to be traced and the tracings to be saved in a format that facilitates review and revision. The traced structures can also be exported in the UCF format that is used by many of the tools in the UCLA Laboratory of Neuroimaging. These include tools for simple measurements (e.g., areas, volumes, lengths, width, surface areas, etc.) as well as tools that resample the tracings into surface meshes that can be analyzed and displayed.

Requirements:

• Images must be in Analyze format (can be PC or UNIX versions)
• Java 1.3 or higher (available for PC's, Mac OS X, and most UNIX platforms)

Descriptions of the following topics are available:

• Launching Tracer
• Loading an image
• Adjusting image brightness
• Changing image orientation
• Handling anisotropic voxels
• Changing image display size
• Viewing data
• Refreshing the display
• Defining a structure that will be traced
• Tracing a defined structure
• Modifying a tracing
• Saving traces
• Reloading saved traces
• Exporting traces as UCF's
• Analyzing UCF's
• Loading a reference image for side-by-side display
• Unloading a reference image
• Editing an image
• Repairing a badly edited image
• Quitting Tracer
