A Three-Dimensional User Interface for Neurosurgical Visualization
نویسندگان
چکیده
We describe a three-dimensional user interface for pre-operative neurosurgical planning based on the physical manipulation of familiar real-world objects in free space. Using these passive interface props, neurosurgeons can apply their existing skills to specify spatial relationships in a natural and direct manner. The interface currently employs a head viewing prop, a cuttingplane selection prop, and a trajectory selection prop. Each prop is a simple real-world tool, the position and orientation of which is tracked by the computer. The behaviors associated with each prop serve as “interaction primitives” which can be composited to describe complex spatial relationships, resulting in a powerful, expressive, and conceptually simple user interface. From the surgeon’s perspective, the interface is analogous to holding a miniature skull which can be “sliced” and “pointed to” using the cutting-plane and trajectory props. Our informal evaluation sessions have shown that with a cursory introduction, neurosurgeons who have never seen our interface can understand and use it without training.

Interactive Visualization of Three-Dimensional Segmented Images for Neurosurgery
Visualization for neurosurgical applications requires speed, realism, and methods for unobtrusive and intuitive interactive exploration. The method presented here uses fast voxel projection to multiple compositing buffers together with a hybrid user interface which includes six degree-of-freedom props.
متن کاملThe props-based interface for neurosurgical visualization.
We describe a three-dimensional human-computer interface for neurosurgical visualization. The interface is based on the two-handed physical manipulation of hand-held tools, or "props", in free space. These user interface "props" facilitate transfer of the user's skills for manipulating tools with two hands to the operation of a user interface for visualizing 3D medical images, without need for ...

OBJECTIVE: Mastery of the neurosurgical skill set involves many hours of supervised intraoperative training. Convergence of political, economic, and social forces has limited neurosurgical resident operative exposure. There is need to develop realistic neurosurgical simulations that reproduce the operative experience, unrestricted by time and patient safety constraints. Computer-based, virtual ...
متن کاملA Visualization Environment for Fused Multi-dimensional Data Analysis and Navigation in Remote Sensing Applications
We present a visualization environment for multi-dimensional, multi-source data analysis and navigation. The system consists of a number of components for three-dimensional terrain generation, image fusion, ground data rendering, and a navigation and data analysis interface. We implement a neural network architecture to fuse four spectral bands from Landsat 5 data. The four bands correspond to ...
