CASS Brain Mapping Module
The CASS Brain Mapping System allows simultaneous display, manipulation, and/or cross-correlation of various brain mapping modules, such that data from various mapping techniques can be related to each other in a normalized computer mapping environment. A proprietary mapping method, utilizing brainstem referenced coordinate systems constructed about the third and fourth ventricular cores of the brain, is used to create comprehensive anatomical-physiological maps. The brainstem coordinate system is designed to compensate for the variable angular relationship of the lower with the upper brainstem. Anatomical, physiological and other topographical data are used in conjunction with internationally recognized nomenclature to create a normalized whole brain mapping system. The CASS Brain Mapping System can be used in conjunction with MR, CT, angiographic, and other brain imaging techniques. This mapping technique can be used in conjunction with any of the CASS imaging or treatment planning modules.
Brainstem Anatomical Maps
Digitized diencephalic and lower brainstem anatomical maps
from the stereotactic atlases of Schaltenbrand and Bailey,
Van Buren and Borke, and Schaltenbrand and Wahren, can be custom-fitted to each patient's brain dimensions as defined by CT and MR imaging. These maps can be individually scaled and superimposed over any patient's brain image for specific mapping purposes.
Electrophysiological maps consisting of a database of over 2500 electrophysiological responses from per-operative stimulation and recording in-and-about the thalamus (see above image). User specified custom maps for data entry into the mapping system are available for the user to enter their own data.
Whole Brain Proportional Mapping System
A refined Talairach/Tournoux whole-brain proportional mapping technique is utilized to create a normalized probabilistic volume mapping system from image data sets.
Comprehensive Integration and Cross-correlation
All mapping systems can be integrated to create composite individualized brain maps. Brodmann's cortical architectonics are also integrated into the system for complete cortical topography.
