Paper Abstract

A computerized brain atlas data base has been developed, primarily for use in positron emission tomography. The underlying information was derived from a digitized cryosectioned cadaver brain. The atlas can be individually adjusted to fit a wide range of patients with reasonable accuracy. The necessary transformations are chosen so that the atlas will fit an initial set of CT or NMR images of the patient. The individualized brain atlas opens several new possibilities in the quantification and evaluation of PET data. It can - be used to select a suitable patient orientation during the PET study, - improve the attenuation and scatter corrections, - supply external information to be used in the image reconstruction, such as proper 3-dimensional regions of interest, - serve as a vehicle in the comparison of different examinations of the same patient, thus reducing the need of reproducible fixation systems, - facilitate the merging and comparison of results from different individuals or groups of individuals (i.e. serve as a reference atlas). The brain atlas can also be used with other imaging modalities as well as in stereo-taxic surgery.
