Parametric anatomical modeling [PDF]
Frontiers in Neuroanatomy, 2014 Computational models of neural networks can be based on a variety of different parameters. These parameters include, for example, the 3d shape of neuron layers, the neurons' spatial projection patterns, spiking dynamics and neurotransmitter systems. While many well-developed approaches are available to model, for example, the spiking dynamics, there is

Anatomically based modeling [PDF]
Proceedings of the 24th annual conference on Computer graphics and interactive techniques - SIGGRAPH '97, 1997 We describe an improved, anatomically based approach to modeling and animating animals. Underlying muscles, bones, and generalized tissue are modeled as triangle meshes or ellipsoids. Muscles are deformable discretized cylinders lying between fixed origins and insertions on specific bones.

Bone graft harvested from the olecranon—an anatomic study
JSES International, 2022 Background: Bone grafts are widely used in orthopedic surgeries. Although the conventional iliac crest graft is still the largest source of cancellous and cortical-cancellous bone grafts, it may require a new surgical field and additional anesthesia.

Training models of anatomic shape variability [PDF]
Medical Physics, 2008 Learning probability distributions of the shape of anatomic structures requires fitting shape representations to human expert segmentations from training sets of medical images. The quality of statistical segmentation and registration methods is directly related to the quality of this initial shape fitting, yet the subject is largely overlooked or ...

Nonparametric joint shape learning for customized shape modeling [PDF]
, 2010 We present a shape optimization approach to compute patient-specific models in customized prototyping applications. We design a coupled shape prior to model the transformation between a related pair of surfaces, using a nonparametric joint probability ...

3D printing of canine hip dysplasia: anatomic models and radiographs [PDF]
Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2020 Canine Hip Dysplasia (CHD) is a highly prevalent articular pathological condition. In this sense, radiography becomes an important diagnostic method to determine the presence and severity of the disease.

Microsurgical training model with nonliving swine head. Alternative for neurosurgical education [PDF]
Acta Cirúrgica Brasileira, 2014 PURPOSE: This paper proposes a practical model of microneurosurgical training using a nonliving swine head. METHODS: Fresh porcine heads were obtained from butchery and dissected at our Laboratory of Microsurgery.
