摘要
在体研究了人体手厥阴心包经及其周围非经络组织的光传输特性。应用点阵结合法对包含手厥阴心包经的一个区域漫射光强度空间分布进行了无损测量。并对该区域的漫射光强度进行了整体分析,在漫射光强度分布的三维图上观察到有明显的线状凹陷,其位置与经络两侧的肌腱相吻合。结果表明,该方法可以有效地测出体表漫射光的空间分布。将实验数据进行三次样条插值处理,发现光波沿手厥阴心包经方向和其他非经络方向传播时的衰减程度存在明显的差异(p<0.05)。在比较的5个方向中,手厥阴心包经方向为漫射光强度衰减最小方向,并且与经络方向偏离越大,漫射光沿该方向衰减越快。
Abstract
The light-transport characteristics of the pericardium meridian and its surrounding non-meridian tissue are studied in vivo. An experimental scheme is established for noninvasively measuring the space distribution of diffuse light in an area including the pericardium meridian with the method of combination of dots and matrix. The distribution of diffuse light in the area are studied integrally. Two obvious linear dips are observed on the 3D image of the distribution of diffuse light, and their location coincides with the tendons on the two sides of the pericardium meridian. The study suggests that with this method the space distribution of diffuse light on the surface of body can be measured effectively. The experimental data is processed with the method of cubic spline interpolation. The study suggests that there is a significant difference between the propagations along the meridian direction and the non-meridian direction (p<0.05). In the five specific directions the light attenuation along the pericardium meridian is significantly less than that along the other non-meridian directions. The larger the angle between the meridian direction and the non-meridian direction, the faster the diffuse light attenuates along this non-meridian direction.
