Abstract

Principles of coherent and non-coherent double exposure Speckle photography are presented with evaluation of shift changes in continuous and discrete areas. The aim of this work is to demonstrate that this computer method can be also employed in medical research. It may be transformed for the study of small deformations of the specimens of lumbar spines during applications of different physical strains.•Incoherent computer speckle interferometry was used to visualize small changes in the assessment of lumbar spine surgical fixation.•Vertebral movement is contactless monitored by two cheap CCD cameras and evaluated using computer technology.•The results obtained were verified on a cadaveric sample of human spine.

摘要

介绍了相干和非相干双曝光散斑摄影的原理，并对连续和离散区域的位移变化进行了评估。这项工作的目的是证明这种计算机方法也可用于医学研究。它可以转化用于研究在施加不同物理应变时腰椎标本的微小变形。

•采用非相干计算机散斑干涉术来可视化腰椎手术固定评估中的微小变化。

•通过两个廉价的电荷耦合器件（CCD）相机对椎体运动进行非接触式监测，并使用计算机技术进行评估。

•在人体脊柱的尸体样本上验证了所获得的结果。
