Abstract:
3D-VIEWER is a new software tool for neurosurgical planning and population studies.
It is based on digitized three-dimensional brain atlases derived from standard stereotactic
atlases that can be adapted to an individual’s brain and shown as a series of displayed
images. If the patient’s brain has been imaged in different modalities, the standardized
anatomical information can be adapted to the individual images, which will bring the
images into registration. The 3D-VIEWER can be used as a tool for combining multimodal
information from the same patient. In addition, several tools are available that allow
oblique views of anatomical structures or the view along the intended trajectory during
a neurosurgical intervention. Furthermore, using the atlas transformation matrices,
anatomical information can be determined when comparing an individual’s brain to the
anatomy of the atlas brain. Thus, standardized anatomical information from the atlas
can be introduced into individual images. This standardization is used to perform
individual-group and group-by-group comparisons between patients and normal controls
in anatomical studies.
