The AstroMed project at Harvard University’s Initiative in Innovative Computing (IIC) is working on improved visualization and data sharing solutions applicable to both the fields of astronomy and medicine. The 3D Slicer and OsiriX medical imaging programs have been used to make isosurface and volumetric models of spectral line data cubes from the COMPLETE Survey of Star Forming Regions. Both programs are open source and built on the ITK and VTK toolkits. We have already used 3D Slicer and OsiriX on COMPLETE's 150,000-spectrum (8-square degree) spectral line maps of Perseus, both to detect outflows and to better understand the cloud structure. One particularly illuminating result shows how existing 3D astronomical "segmentation" algorithms (e.g. CLUMPFIND) often break up the cloud into structures humans (and possibly physics) would not select as most meaningful. Future work for AstroMed includes continuing to make 3D Slicer more compatible with astronomical data, and continuing to apply it to these and other astronomical research projects. All IIC developed tools, as well as 3D Slicer and OsiriX, are freely available, through iic.harvard.edu.
