| − | ===Module Description===
| |
| − | The goal of this project is the creation of interfaces in Slicer3 that integrate the EMSegment algorithm (Pohl et al.), an automatic segmentation algorithm for medical images that previously existed in Slicer 2. As in Slicer 2, the user is able to adjust the algorithm to a variety of imaging protocols as well as anatomical structures and run the segmenter on large data sets. Three views or interfaces to the algorithm are available: a wizard-based module for building and editing parameter sets, a simplified "one-click" GUI module, and a command line interface for script and batch processing.
| |
| − | | |
| − | As of January, 2008, working versions of all EMSegment interfaces are complete and have been checked into the Slicer3 SVN repository. Recent development effort has focused on providing simplified interfaces to the algorithm, reducing assumptions about input data, testing, and validation. The module was demonstrated at the NAMIC All-Hands meetings in Salt Lake City (2007 and 2008). A tutorial has been developed and is available from this page.

| − | ====EMSegment Workflow Module====
| |
| − | | |
| − | The EMSegment worfklow module is the primary Slicer3 interface to the EMSegment algorithm. The target audience for this module is someone familiar with brain atlases and tissue labels, not a computer scientist. It allows the user to configure the algorithm---step-by-step---to a variety of imaging protocols and anatomical structures, and then apply the algorithm to segment data. Configuration settings are stored in an EMSegment parameters node in the Slicer3 MRML tree. These settings can be saved and later applied to new data via any of the EMSegment interfaces within Slicer3 or the command-line EMSegment executable.
| |
| − | | |
| − | A similar EMSegment module is available in Slicer2.6. The intent of
| |
| − | this project is to implement a Slicer3 module with similar
| |
| − | functionality while also improving the graphical user interface (GUI).
| |
| − | While the GUI and data structure (MRML) code was completely rewritten
| |
| − | for the Slicer3 module, the algorithm code was not modified.
| |
| − | | |
| − | ====EMSegment Command-line Executable====
| |
| − | | |
| − | The EMSegment command-line executable is used to simplify the processing of large collections of images. The primary function of the '''work flow''' module is to step the user through the process of calibrating, via algorithm parameters, the segmentation algorithm to a particular set of input data. However, once a successful collection of parameters is established, the user will commonly want to bypass this detailed calibration process when segmenting new images. The command-line executable provides this batch processing capability.
| |
| − | | |
| − | The executable is included in the Slicer3 distribution.

| − | ===Usability issues===
| |
| − | | |
| − | The EMSegmenter can be adapted to many segmentation problems. However, there is no "default" set of parameters that will work for all segmentation problems.
| |
| − | *Atlas-to-target registration and intensity normalization are very important; it will be most effective to apply these steps using algorithms that are customized to your data. Defaults are provided but they may perform poorly for your data---this will lead to poor segmentation results.
