Computer model of an inhomogeneous human torso

Area of Science:

• Anatomical modeling
• Computational biology
• Biomedical engineering

Background:

• Accurate anatomical models are crucial for physiological simulations.
• Existing models may lack the detailed resolution required for specific research applications.
• The human torso contains complex structures vital for understanding cardiac function.

Purpose of the Study:

• To introduce a detailed three-dimensional computer model of the human torso.
• To create a high-fidelity model of the heart chambers (left ventricle, right ventricle, left atrium, right atrium) and lungs.
• To validate the model's utility for electrocardiogram (ECG) simulation research.

Main Methods:

• Construction of a 3D computer model based on an atlas of sectional human anatomy.
• Development of algorithms for detailed model generation.
• Utilizing over 10,000 surface triangles to represent anatomical structures and proportions.
• Focusing on precise depiction of the heart and lung anatomy.

Main Results:

• A comprehensive 3D computer model of the human torso was successfully created.
• The model accurately represents the four heart cavities and two lung lobes.
• The detailed myocardial model and overall torso structure were established.
• Algorithms for model construction are presented in detail.

Conclusions:

• The developed 3D torso model provides a high-fidelity anatomical representation.
• The model's accuracy and detail make it suitable for advanced simulation research.
• The study discusses the model's validity for electrocardiogram simulation, paving the way for further research.
