To develop and evaluate an adaptive MRI segmentation method that models boundary topography to enhance the detection of longitudinal brain tissue changes.
Incorporated edge operators to detect tissue interfaces and model voxel label dependencies across synthetic and clinical scans.
Evaluated performance against FAST and SPM5 segmentation tools using synthetic MRI templates corrupted with additive noise and longitudinal MRI series.
Achieved more consistent tissue labeling across varying noise levels on synthetic templates compared to both FAST and SPM5.
Reduced variability in individual longitudinal trajectories of tissue change, indicating superior discrimination of true anatomical alterations from imaging artifacts.
