评估μCT输出的牙科研究通常将分辨率作为影响数据的参数进行检查，但许多其他因素也会影响图像质量。本文的目的是提出与优化的μCT数据采集和处理的两个生物力学动物模型所涉及的问题。第一个模型评估了狗切牙体外疲劳载荷后牙根结构的表面和体积变化。第二部分评价了近交系和转基因小鼠在正畸力作用下的骨和牙齿的活体形态测量反应。这种类型的数据需要特定的放大倍率和噪声控制μCT设置，以分割和渲染具有可接受清晰度的对象。所提出的程序，使高清晰度呈现牙齿和骨骼形态的变化，正畸研究。它们还允许构建用于有限元分析的实体模型。
Dental studies evaluating μCT output often examine resolution as a parameter that affects the data, but many other factors can influence image quality. The objective of this paper is to present the issues involved with the optimization of μCT data acquisition and processing for two biomechanical animal models. The first model evaluates surface and volumetric changes in root structure afterin vitrofatigue loading of dog incisors. The second evaluates thein vivomorphometric bone and tooth responses to application of orthodontic force in inbred and transgenic mice. This type of data required specific magnification and noise control μCT settings to segment and render objects with acceptable definition. The proposed procedures enabled high definition rendering of changes in tooth and bone morphology in orthodontic studies. They also allowed for the construction of solid models for finite element analyses.
