Three-Dimensional Neuroimaging Using Octree Encoding

摘要

As part of an effort to design an expert system for interpreting images of the nervous system, we have developed computer programs to display and manipulate three-dimensional images. Tissues of differing radiodensities, include soft tissues can be extracted without the need for human tracing, and composite images of structures of different densities may be built. The method is applicable to any digital imaging modality (CT, MRI, local cerebral blood flow, or PET). All programming was done in the C programming language under the UNIX operating system.
