Co-analysis of Maps of Atrophy Rate and Atrophy State in Neurodegeneration
The variability in atrophy rate in patients with neurodegenerative disease can be partially explained by disease stage. Since atrophy state (baseline scan tissue volume) correlates with cognitive impairment an...

Steps Toward a Stereo-Camera-Guided Biomechanical Model for Brain Shift Compensation
Surgical navigation systems provide the surgeon with a display of preoperative and intraoperative data in the same coordinate system. However, the systems currently in use in neurosurgery are subject to inaccu...

Evaluation of the limits of visual detection of image misregistration in a brain fluorine-18 fluorodeoxyglucose PET MRI study
In routine clinical work, registration accuracy is assessed by visual inspection. However, the accuracy of visual assessment of registration has not been evaluated. This study establishes the limits of visual ...
