As 3D volumetric images of the human body become an increasingly crucial source of information for the diagnosis and treatment of a broad variety of medical conditions, advanced techniques that allow clinicians to efficiently and clearly visualize volumetric images become increasingly important. Interaction has proven to be a key concept in analysis of medical images because static images of 3D data are prone to artifacts and misunderstanding of depth. Furthermore, fading out clinically irrelevant aspects of the image while preserving contextual anatomical landmarks helps medical doctors to focus on important parts of the images without becoming disoriented. Our goal was to develop a tool that unifies interactive manipulation and context preserving visualization of medical images with a special focus on diffusion tensor imaging (DTI) data. At each image voxel, DTI provides a 3 x 3 tensor whose entries represent the 3D statistical properties of water diffusion locally. Water motion that is preferential to specific spatial directions suggests structural organization of the underlying biological tissue; in particular, in the human brain, the naturally occuring diffusion of water in the axon portion of neurons is predominantly anisotropic along the longitudinal direction of the elongated, fiber-like axons [MMM+02]. This property has made DTI …

Interview with Evelyn Brown, Vietnam War-era veteran of the US Navy, as part of the Tarrant County War Veterans Oral History Project. The interview includes Brown's personal experiences of childhood and education in Pennsylvania, attending nursing school, enlisting in the Navy Nurse Corps, and being involved with veterans organizations. Additionally, Brown discusses her coming out experience, her assignment to facilities in Florida, Guantanamo Bay, Cuba, Camp Lejeune, N.C., and Quantico, Virginia, her decision to leave service upon assignment to USS Sanctuary, a hospital ship stationed off the coast of Vietnam, and her opinions regarding the "don't ask, don't tell" policy.

Interview with Arthur Hofstein, a Army WWII veteran from Cambridge, Massachusetts. Hofstein discusses the lead up to war, being drafted, training to be a radio operator, departure for the European Theater, landing in France and first action at Mars-la-Tour, the Battle of the Bulge, German prisoners and civilians, advancing into Germany, the liberation of Dachau, letters, and life after the war. In appendix are various materials and photographs related to Hofstein and his service.
