Pulse differences and 3D pulse mapping in TPNI displacements

Pulse diagnosis is one of the most important examinations in Traditional Chinese Medicine (TCM). Regardless the fact of the subjectivity and fuzziness of pulse diagnosis in TCM, the displacement of Fu (superficial pressure), Zhong (medium pressure), Chen (deep pressure) at the location of Cun (upper), Guan (medium), Chi (lower) on the wrist during pulses diagnosis is still under discovering so far. In this paper, a novel Bi-Sensing Pulse Diagnosis Instrument (BSPDI) was provided quantifiable Traditional Chinese Medicine Pulse Diagnosis (TCMPD) research. Moreover, using signal processing algorithms, the core characteristics of three-dimension pulse mapping (3DPM) are identified, including strength, rate, length, width and trends. BSPDI can conduct the quantitative research of pulse diagnosis to discover the empirical finger-reading models published in the TCM books.
