Spatial Displays and Interaction for Image Guided Therapy

1. Spatial Displays and Interaction for Image Guided Therapy Image Guided Therapy Program Brigham and Women’s Hospital Michael Halle Ph.D. and Wendy Plesniak Ph.D. Surgical Planning Laboratory, Brigham and Women’s Hospital Harvard Center for Neurodegeneration and Repair, Harvard Medical School Computational infrastructure 3D Slicer forms a common computational core for data processing and visualization within the IGT programs. The visualization core will add new functionality to Slicer for providing common frameworks for input and output devices, shielding developers from many of the details of different technologies. Standard frameworks allow rapid prototyping for new applications and environments, simplified development, reduced code complexity, and more standardized evaluation and testing. The experience that developers build and users gain with one display system, for example, can transfer to their experiments with new displays. Display & Interaction Different display devices provide different kinds of information: 3D, animated, real-time, or high resolution. No one display technology currently addresses all the requirements for all therapy applications. In addition, some displays are more available or approachable than others. The visualization core will develop navigation and interaction techniques that build context between different display and interface technologies, integrating them to provide as well as provide intuitive interaction for specific IGT applications.

Needs & use assessment Image guided therapy includes a wide range of medical procedures performed in different clinical environments, from the reading room, to surgery, to the MR magnet. New display and interface technology will be incorporated into new environments through an initial assessment of environmental constraints, a needs assessment for the procedure and tasks involved, and an ongoing evaluation of effectiveness of prototype devices and applications. As promising new display and interface technologies emerge, they will be integrated into our common framework for experimentation, development, and deployment.
