Coupling Axis-Length Profiles with Bezier Splines in Finite Element Head Models

Applying Craniofacial Metrics to Adapt 3D Generic Head Models

“…Simple generic models simulate down-sampled and smoothed tissue boundaries (Kybic et al, 2006;Wendel, Osadebey & Malmivuo, 2008;). These models represent larger groups of people through their approximated shapes and sizes.…”

“…They will optimize the deformation, i.e., adaptability, of head models by minimizing the need for expensive MRIs and CTs, and eliminating the segmentation time. As scalp and skull tissue atlases are compiled and analyzed across age, gender, and ethnicity, the understanding of how to apply changes to a template will improve a model to match the non-imaged patient (Wendel, Osadebey & Malmivuo, 2008;. Ultimately, incorporating the exact electrode locations to guide the deformation according to the patient's scalp surface would improve this method (Darvas et al, 2006;van 't Ent et al, 2001).…”

“…Our goal is to make deformable generic head models readily available for individuals who have not been medically imaged. The radial vector technique was briefly described in Wendel, Osadebey & Malmivuo (2008;. The full mathematical description of the radial vector technique manipulating the radial angular matrix (RAM) can be found in Wendel et al (2012).…”
