本文提出了两种不同的数学方法，可以单独使用或结合使用，以适应正常人体神经解剖之间的形状变异。这两种方法都使用数字化教科书来表示典型正常神经解剖学的复杂结构。教科书坐标系上的概率变换被定义为适应教科书和其他正常神经解剖结构的图像之间的形状差异。在第一种方法中，变换被约束为与可变形弹性固体的物理性质一致，而在第二种方法中，变换被约束为与粘性流体的物理性质一致。本文提出的结果表明，如何一个单一的变形教科书可以用来适应正常的形状变化。
This paper presents two different mathematical methods that can be used separately or in conjunction to accommodate shape variabilities between normal human neuroanatomies. Both methods use a digitized textbook to represent the complex structure of a typical normal neuroanatomy. Probabilistic transformations on the textbook coordinate system are defined to accommodate shape differences between the textbook and images of other normal neuroanatomies. The transformations are constrained to be consistent with the physical properties of deformable elastic solids in the first method and those of viscous fluids in the second. Results presented in this paper demonstrate how a single deformable textbook can be used to accommodate normal shape variability.
