| 中文摘要: |
| 激光散斑衬比成像技术可以为中医理疗提供无创、高效的疗效评估手段，但目前该评估方法的稳定性有待提高。基于能产生稳定散斑衬比的近红外激光光源，对针灸疗效进行散斑成像实验并获得原始实验数据，分析对比Roll算法与基于此算法加入时间抽样形成新的衬比处理RT（Roll with time-sampling）算法的数据处理结果。从衬比随时间分布的规律可以看出，RT算法处理所得的衬比分布更加均匀，消除了部分噪声干扰，因此RT算法能够提升激光散斑衬比分布的稳定性。 |
| 英文摘要: |
| Laser speckle contrast imaging (LSCI) technology can provide non-invasive and highly effective therapeutic evaluation method for traditional chinese medicine physical therapy. However, the stability of this assessment method needs to be improved. Based on near infrared laser light source, the speckle imaging experiment was performed and the original experimental data was obtained. The data processing results of the new contrast processing algorithm based on RT(Roll with time-sampling) were analyzed. It can be seen that based on the regularity of the contrast distribution the distribution obtained by the RT algorithm was more even as some of the noise was filtered. Therefore, RT algorithm could improve the stability of the laser speckle contrast distribution. |
