【摘要】：目的：通过提取多维的脉诊触觉信息,并将其转化为可视化动态三维图形,构建符合中医脉诊指感描述的动态三维指感脉图,为脉诊的“全信息”交流提供手段。方法：根据人体指面产生触觉的生理学机理,硅压力传感器裸芯(Die)作为传感器件,埋植于柔性硅橡胶表面内,构成模拟指面的压力敏感表面,形成柔性面接触型传感模式,以获得适于脉诊研究的技术参数。利用双三次样条插值函数将网格由4层六边形加密为7层六边形阵列,提高了图像的分辨率及边缘精度,为三维图像的快速重建提供了方便。结果：以阵列式压力传感器为核心搭建的动态压力分布采集系统,经过信号分析与多信息融合处理,构建出了中医脉诊动态三维指感脉图。结论：通过几十例的受试者脉诊信息采集,本文的阵列式压力传感系统能够用于取脉点动态压力分布的采集,所获得的可视化动态三维图形,丰富了脉诊提取的信息量,极大地拓宽了中医师获取脉诊信息的途径,有望建立一种全新的中医脉诊客观化检测与评价方法。
[Abstract]:Objective: by extracting multidimensional palpation information and transforming it into visualized dynamic three-dimensional graphics, we can construct dynamic three-dimensional finger pulse map which accords with the description of finger sense of traditional Chinese medicine (TCM), and provide a means for "full information" communication of pulse diagnosis. Methods: according to the physiological mechanism of tactile on human finger surface, the bare core (Die) of silicon pressure sensor was planted on the surface of flexible silicone rubber as sensing device, forming the pressure sensitive surface of simulated finger surface and forming the contact sensing mode of flexible surface. To obtain the technical parameters suitable for pulse diagnosis. The double cubic spline interpolation function is used to encrypt the mesh from 4-layer hexagonal to 7-layer hexagonal array, which improves the resolution and edge accuracy of the image, and provides convenience for the fast reconstruction of 3D images. Results: the dynamic pressure distribution acquisition system based on array pressure sensor was constructed by signal analysis and multi-information fusion. Conclusion: by collecting pulse information of dozens of subjects, the array pressure sensing system can be used to collect the dynamic pressure distribution of pulse point, and the visual dynamic 3D figure is obtained, which enriches the amount of information extracted by pulse diagnosis. It greatly broadens the way for traditional Chinese medicine doctors to obtain pulse diagnosis information and is expected to establish a new method for the objective detection and evaluation of pulse diagnosis in traditional Chinese medicine.
