An improved finite-element contact model for anatomical simulations
The Visual Computer, 2003This work focuses on the simulation of mechanical contact between nonlinearly elastic objects, such as the components of the human body. In traditional methods, contact forces are often defined as discontinuous functions of deformations, which leads to poor convergence characteristics and high-frequency noises.

Elemental composition of anatomically distinct regions of rat liver
Biological Trace Element Research, 1999Experiments were conducted to test the commonly held assumption that analysis of a portion of rat liver is representative of the elemental concentration of the whole organ. Male Sprague-Dawley rats (initial body weight approximately 250 g) fed a chow diet or weanling male Long-Evans rats (initial body weight approximately 50 g) fed a semipurified diet ...

Wood Anatomic Elements With Acoustic Microscopy
1996The main interest in acoustic microscopy arises from the direct interaction between the wave and the elastic properties of the material through which it propagates. Acoustic waves permit the exploration of the region of specimen beneath the surface.

Anatomic Variability of the Neurovascular Elements Defined by MRI
Brachytherapy, 2014described a system of ultrasound and fluoroscopy based seed localization (RUF) for intraoperative dose calculation, and sought to prospectively evaluate its accuracy in predicting post-implant dosimetry compared to standard ultrasound-based dosimetry.

Association of variance in anatomical elements of myocardial bridge with coronary atherosclerosis
Atherosclerosis, 2013The myocardial bridge (MB) is an anatomical structure consisting of myocardium covering a part of the left anterior descending coronary artery (LAD). The extent and spatial distribution of atherosclerosis in the LAD with an MB is influenced by the anatomical properties of the MB.

Thoughts on practical core elements of an ethical anatomical education
Clinical Anatomy, 2015While questions of ethics in body procurement have become a focus of attention in many medical schools around the world, the recent report by a medical student regarding disturbing incidences in an anatomical dissection course (Terry, ) underlines the importance of a discussion of ethical practices in anatomical education.

Finite element analyses for predicting anatomical neck fractures in the proximal humerus
Clinical Biomechanics, 2019Proximal humerus fractures which occur as a result of a fall on an outstretched arm are frequent among the elderly population. The necessity of stabilizing such fractures by surgical procedures is a controversial matter among surgeons. Validating a personalized FE analysis by ex-vivo experiments of humeri and mimicking such fractures by experiments is ...

An Anatomically Based Finite Element Model of the Lower Limbs in the Seated Posture
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007In this study an anatomically accurate 3D Finite Element (FE) model of the lower limbs was developed from axial cryosection images of the Visible Man (VM). The relative position of the lower limbs of a subject in standing and sitting positions was acquired with a laser scanner.

ASME 2012 Summer Bioengineering Conference, Parts A and B, 2012
Although mitral valve (MV) repair initially restores normal leaflets coaptation and stops MV regurgitation, in long term it can also dramatically change the leaflet geometry and stress distribution that may be in part responsible for limited repair durability.

Anatomical registration and segmentation by warping template finite element models
SPIE Proceedings, 1998Image segmentation and anatomical registration play an important role in subject-specific computational modeling and image analysis. Often a three-dimensional (3D) segmentation is available for a canonical template image dataset of a single subject.
