Anatomical structure modeling from medical images
Computer Methods and Programs in Biomedicine, 2006Some clinical applications, such as surgical planning, require volumetric models of anatomical structures represented as a set of tetrahedra. A practical method of constructing anatomical models from medical images is presented. The method starts with a set of contours segmented from the medical images by a clinician and produces a model that has high ...

Patient-Specific Anatomic Models
1996Virtual reality offers the promise of highly interactive, natural control of the visualization process, greatly enhancing the scientific value of the data produced by medical imaging systems. Due to the computational and real time update requirements of virtual reality interfaces, however, the complexity of polygonal surfaces which can be displayed is ...

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.

Anatomically accurate, finite model eye for optical modeling
Journal of the Optical Society of America A, 1997There is a need for a schematic eye that models vision accurately under various conditions such as refractive surgical procedures, contact lens and spectacle wear, and near vision. Here we propose a new model eye close to anatomical, biometric, and optical realities.

Anatomical Accuracy in Medical 3D Modeling
2001In complex surgery, medical modeling has become an accepted tool for diagnosis, simulation and the planning of surgical interventions [1]. However, the question concerning the accuracy of the model, i.e. the equivalence between the model itself on the one hand and the original anatomical situation on the other hand, remains unanswererd in the current ...

Computerized Anatomical Model Man
1970Abstract : The Computerized Anatomical Model Man is a detailed representation of the radiation transport properties of the human body. It is to be used for computation of the areal density distribution at specified locations in the body. This information is applicable to dose calculations in natural, weapon, reactor, and other radiation environments ...

Anatomical models for medical images
COMPSAC 79. Proceedings. Computer Software and The IEEE Computer Society's Third International Applications Conference, 1979., 2005We are working towards a general model of the anatomy seen in medical images that can be used to find the boundaries of organs. We argue that such a model must have four components: - multiple resolution copies of the image (pyrarn ids) ; - geometric shape models for organs; - network-like models of inter-organ relationships; and - a top-down control ...

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.

Musculoskeletal Modelling: relevance of model anatomical consistency
2021No consensus exists on how to model human articulations within musculoskeletal models (MSKM). We propose to evaluate a joint model based on their anatomical consistency (AC), i.e. by quantifying ligament and cartilage deformation associated to its motion: to be consistent with articular physiology this deformation should be minimum.
