The author presents an overview of the state of the art in biomedicalvisualization and simulation and provides a brief tutorial on the various computer graphics modeling representations, with pointers toward more in-depth information. A set of properties based on empirical knowledge of the properties of the structures and organisms concerned, yet sensitive to the current limitations of the ability of computers to model the physical world, is put forth. A brief discussion of many biological phenomena whose study would be well served by utilization of the graphics and simulation techniques discussed is presented.

The use of images of a patient's internal anatomy as the basis for the design and optimization of radiation treatment plans, the precise identification of the target disease volume and normal surrounding organs, the importance of verifying the delivery of presented therapy, and the visualization and correlation of computer tomography and magnetic resonance imaging volumes to facilitate treatment are discussed.

The authors discuss the implementation of a method of image registration that uses the edges of common features and is suited to the coarse grain parallel model of communicating sequential processes. Results are given for performance of sections of the algorithm on a small network of transputers. Some of the factors which must be considered in using a parallel system are discussed.

An ergonomic design of a user interface which considers human factors is discussed. Based on a model of the anesthesiologist's monitoring task, the user interface design of an anesthesia decision support system is described as an example. The essential aspects of this user interface comprise appropriate information structure, information coding by color and shape, user guidance, and interaction by means of a touch input facility.

A system of graphical software tools to facilitate the two-dimensional visualization of primary and model data is described. The system uses a direct manipulation interface developed at Duke University Medical Center. This system presents the investigator with different tools to view and manipulate data in various ways and with the ability to cut and paste between display modes. A formal description of the standardized self-documenting file structure used by these tools and a description of the display and manipulation tools that make up the system are presented. Examples derived from current use demonstrate how visualization facilitates exploration and analysis by direct manipulation.

visualization tools common to the areas of molecular, cellular, and anatomical imaging are explored. These tools address four major problem areas common to visualization of molecular, cellular, and anatomical structures: (1) presentation of visual representation;(2) correlation;(3) quantitation and understanding;(4) data management. The authors address general requirements for three-dimensional biovisualization but do not explore modes of implementation or application-specific problems.

A method for the visualization of the electroencephalogram (EEG) in phase space is described. The signal is transformed from the time domain to phase space by measuring the correlation dimension of the data and constructing the attractor in the required embedding space, which is normally of dimension 3 to 8. A singular value decomposition is used to obtain a good projection to 3-D. Animation of a series of 2-D rotated projections provides a way to visualize the fine structure of the reconstructed 3-D attractor. Examples and a computer package are briefly described.

A representation of image intensity structure, the multiscale orientation field (MOF), is described, and its application to biomedical image segmentation is discussed. The MOF is composed of orientation vectors at every pixel and at multiple scales. The vectors are computed from the outputs of an artificial visual system composed of spatial filters whose design is described. An abstract feature space for orientation measurement is defined, and a filter sensitivity function that yields a desirable mapping into the feature space is described.

The use of visualization in five neuroscience projects is discussed. The issue of how structural models can be best manipulated to gain insight into nervous system function is addressed. visualization projects that take up this issue from three different user perspectives (research, student, and clinician) are described. Several conceptual and technical issues that these projects (and others like them) pose are considered.
