In this study, we present a magnetic resonance imaging (MRI)-based, high-resolution, numerical model of the head of a healthy human subject. In order to formulate the model, we performed quantitative volumetric segmentation on the human head, using T1-weighted MRI. The high spatial resolution used (1 x 1 x 1 mm(3)), allowed for the precise computation and visualization of a higher number of anatomical structures than provided by previous models.
