This paper emphasizes the growing importance of precise models of biological structures to be used in conjunction with dynamic models of physiological events for improved physiological systems modeling. Medical imaging developments, represented mainly by computerized tomography, have been oriented principally towards medical diagnostic applications, that is towards the obtention of semi-quantitative information using sophisticated three-dimensional image display and manipulation capabilities. On the other hand, three-dimensional reconstruction of objects for modeling purposes presents rather more stringent requirements. The most important are the precise and independent representation and manipulation of the structures involved, the possibility of modifying the model parameters, the access to geometric data for specific measurements and transformation, and the compatibility with CAD/CAM software. Methods to obtain and manipulate such information are becoming available and a particular system used for the geometric modeling of the vertebral spine and knee is outlined.
本文强调精确的生物结构模型与生理事件动态模型相结合对于改进生理系统建模日益重要。主要以计算机断层扫描为代表的医学成像技术发展主要面向医学诊断应用，即利用复杂的三维图像显示和处理能力获取半定量信息。另一方面，为建模目的进行的物体三维重建提出了更为严格的要求。最重要的是对所涉及结构进行精确且独立的表示和处理、修改模型参数的可能性、获取用于特定测量和变换的几何数据以及与CAD/CAM软件的兼容性。获取和处理此类信息的方法正在出现，并且概述了一种用于脊椎和膝盖几何建模的特定系统。
