Abstract

BACKGROUND:Targeting in deep brain stimulation (DBS) relies heavily on the ability to accurately localize particular anatomic brain structures. Direct targeting of subcortical structures has been limited by the ability to visualize relevant DBS targets. METHODS AND RESULTS:In this work, we describe the development and implementation, of a methodology utilized to create a three dimensional deformable atlas for DBS surgery. This atlas was designed to correspond to the print version of the Schaltenbrand-Bailey atlas structural contours. We employed a smoothing technique to reduce artifacts inherent in the print version. CONCLUSIONS:We present the methodology used to create a three dimensional patient specific DBS atlas which may in the future be tested for clinical utility.
