生物力学研究人员对实验测量牙科结构所经历的应力感兴趣,整个骨头,关节置换,软组织,四肢正常,等。要做到这一点,已经使用了各种基于声学的实验方法,光学,压阻,或其他原则,比如数字图像相关,光纤传感器,照片弹性,应变计,超声,等。几篇生物力学综述论文调查了这些研究技术,但他们没有提到热成像。热成像可以识别指示骨骼上低应力或高应力区域的温度异常,植入物,假肢,等。,可能需要修理,替换,或重新设计以避免损坏,降解,或失败。此外,热成像可以准确预测结构的循环疲劳强度。因此,本文对用于生物力学应力分析的热成像科学文献进行了最新调查。这篇综述(I)描述了热成像的基本物理学,生物材料的热弹性特性,热成像实验方案,优势,和缺点,(ii)关于使用热成像技术进行生物力学应力测量的各种应用的调查发表的研究报告,(iii)讨论一般调查结果和未来工作。本文旨在告知生物力学研究人员有关热成像技术在应力分析中的潜力。
Biomechanics investigators are interested in experimentally measuring stresses experienced by dental structures, whole bones, joint replacements, soft tissues, normal limbs, etc. To do so, various experimental methods have been used that are based on acoustic, optical, piezo-resistive, or other principles, like digital image correlation, fiber optic sensors, photo-
elasticity, strain gages, ultrasound, etc. Several biomechanical
review papers have surveyed these research technologies, but they do not mention thermography. Thermography can identify temperature anomalies indicating low- or high-stress areas on a bone, implant, prosthesis, etc., which may need to be repaired, replaced, or redesigned to avoid damage, degradation, or failure. In addition, thermography can accurately predict a structure\'s cyclic fatigue strength. Consequently, this article gives an up-to-date survey of the scientific literature on thermography for biomechanical stress analysis. This
review (i) describes the basic physics of thermography, thermo-elastic properties of biomaterials, experimental protocols for thermography, advantages, and disadvantages, (ii) surveys published studies on various applications that used thermography for biomechanical stress measurements, and (iii) discusses general findings and future work. This article is intended to inform biomechanics investigators about the potential of thermography for stress analysis.
