Network models in anatomical systems.
Journal of anthropological sciences = Rivista di antropologia : JASS, 2011Network theory has been extensively used to model the underlying structure of biological processes. From genetics to ecology, network thinking is changing our understanding of complex systems, specifically how their internal structure determines their overall behavior.

Modeling anatomical heterogeneity in populations
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011Our goal is to model anatomical variability across individuals, which presents substantial challenges in clinical population studies and in building atlases for segmentation. Based on a mixture model for a population, we derive an efficient algorithm that clusters a set of images while co-registering them into a common coordinate frame.

Modeling the Anatomical Distribution of Sunlight¶‡
Photochemistry and Photobiology, 2004ABSTRACTOne of the major technical challenges in calculating solar irradiance on the human form has been the complexity of the surface geometry (i.e. the surface‐normal vis‐a‐vis the incident radiation). Over 80% of skin cancers occur on the face, head, neck and back of the hands.

Anatomical modeling of the bronchial tree
SPIE Proceedings, 2010The bronchial tree is of direct clinical importance in the context of respective diseases, such as chronic obstructive pulmonary disease (COPD). It furthermore constitutes a reference structure for object localization in the lungs and it finally provides access to lung tissue in, e.g., bronchoscope based procedures for diagnosis and therapy.

A framework for predictive modeling of anatomical deformations
IEEE Transactions on Medical Imaging, 2001A framework for modeling and predicting anatomical deformations is presented, and tested on simulated images. Although a variety of deformations can be modeled in this framework, emphasis is placed on surgical planning, and particularly on modeling and predicting changes of anatomy between preoperative and intraoperative positions, as well as on ...

REENTRY IN AN ANATOMICAL MODEL OF THE HUMAN VENTRICLES
International Journal of Bifurcation and Chaos, 2003We study wave propagation in a recently developed model, which reproduces geometry and fiber orientation in the right and left ventricles of the human heart. The cardiac tissue is represented using the previously developed γ-ionic model for human ventricular tissue using a spatial resolution of 0.5 mm.

A SIMPLIFIED TECHNIQUE FOR CASTING ANATOMICAL MODELS
International Journal of Dermatology, 1977ABSTRACT: For anyone desiring to cast anatomical models, a simplified technique for external casting has been developed using dental impression materials readily available in dental supply houses. These impressions yield life‐like permanent models retaining topographical features of normal as well as pathological skin and nails.

A Technique for Kinematic Modeling of Anatomical Joints
Journal of Biomechanical Engineering, 1980This paper describes a general technique for fitting a spatial kinematic model to an in-vivo anatomical joint under typical physiological loading conditions. The method employs a nonlinear least squares algorithm to minimize the aggregate deviation between postulated model motion and experimentally measured anatomical joint motion over multiple joint ...
