三部九候為脈診核心的方法，中醫師把脈時佈指於寸關尺，而施壓浮中沉，以此得不同部位不同深度之脈象。脈象在不同部位與不同深度代表著不同生理訊息。近年來脈診量化研究中多集中探討脈象分類的方法，卻鮮少研究取脈行程之浮中沉量化準則，因而造成眾多研究在重現度沒有一致性。因此，本研究試著提出脈診之浮中沉量化準則，期許建立脈診的標準取脈流程，使得脈診量化研究能建構在同一操作準則上，以提高脈診的臨床應用性。
　　一般在確認脈管被按壓的變化必須借助超音波儀器成像，但此舉複雜化了脈診儀的研發。因此，本研究提出以團隊研發之雙感測脈診儀(Bi-Sensing Pulse Diagnosis Instrument, BSPDI)取得之脈波參數來取代超音波，以簡化取脈過程。實驗方法分別以BSPDI和超音波將脈管壓扁，記錄其按壓深度資料。並在超音波的部分紀錄撓動脈脈管按壓過程直徑的變化，擷取BSPDI完整脈波訊號與脈波參數，作為浮中沉脈位建立的依據。
　　根據中醫師實際取脈之深度，定義浮中沉對應脈管的變化分別為撓動脈脈管按壓15%、45%、75%。實驗結果由超音波得到的脈管按壓百分比與雙感測脈診儀的按壓深度之間的關係，對應浮中沉深度的靜態壓力值，經過一調整機制後可將誤差範圍由29.1%降至16.9%，有效的提高判斷浮中沉各深度的靜壓力值。依據脈管按壓百分比和按壓深度與調整機制來定義浮中沉脈位的準則。
　　本研究利用醫師實際取脈，脈管被按壓程度之等分法來定義浮中沉之脈位，並提出超音波之相關數據做為驗證，有別於多數研究採用壓力做為脈位定義的做法，提供一更加快速與符合生理學的定義方式。本研究最重要的貢獻在以雙感測脈診儀之操作基礎，提出一套定義浮中沉脈位的方法，作為脈診儀把脈的初始標準，以期日後和中醫師臨床經驗進行比對和修正。站在中醫脈診量化的角度，在提出三部九候的脈位深度定義之後，脈像辨識才能有系統與精準的定義，以建立有用的臨床資料庫，如此在中醫脈診量化的研究才能持續的進行，在中醫的傳承與臨床的應用發揮其價值。

　Three Positions Nine Indicators is the main method of pulse diagnosis, physicians do pulse-taking with their fingers on Cum Guan Chi, and press on Fu Zhong Chen, in this way to get pulse of each part and depth. Pulse of each part and depth means different physical signification. Recently, pulse-taking quantify researches are discuss about different type of pulse, but few to discuss about quantitative standards of pulse-taking depth on Fu-Zhong-Chen, that is the reason of there’s no consistency for the research. Therefore, this thesis trying to propose of quantitative standards of pulse-taking, hope we can establish the standard of pulse, to make pulse-taking quantify researches can based on the same principle, in this way to enhance clinical application of pulse-taking.
　Generally, we need ultrasound instrument to get the image of pressed radial artery, but this way complicating the develop of Pulse Diagnosis Instrument. Therefore, this thesis mention that we can use Bi-Sensing Pulse Diagnosis Instrument (BSPDI) instead of ultrasound instrument, to simplified the process of pulse-taking. The experiment is using BSPDI or ultrasound to press artery, and record the press depth data. Also record the diameter variety of radial artery in ultrasound, capture the full pulse signal in BSPDI and analysis pulse parameter for the base on pulse position of Fu-Zhong-Chen.
　According to the practical pulse depth taking from Traditional Chinese doctors, we define the changes of artery corresponding to Fu-Zhong-Chen are 15%, 45% and 75%. We can get experience results by the relationship corresponding to the static pressure value of Fu-Zhong-Chen between pressure percentage of artery and the pressure depth of BSPDI. We can reduce inaccuracy from 29.1% to 16.9% through a monitoring system and effectively rise the accuracy of the static pressure value of each depth of Fu-Zhong-Chen. We can define the position of Fu-Zhong-Chen according to the pressure percentage of artery, the pressure depth, and monitoring system.
　In this research, we equally divide the pulse position depth when pressing on, and defining the pulse position depth into three part, which called Fu-Zhong-Chen. Also, we provide ultrasound experiment data to verify the result which we defined. This research differs from other researches which utilize pressure to be the parameter of definition, the definition in this research is faster and suitable in physiological aspect. The most important contribution of this research is that we establish a standard which defining pulse parameter of Fu-Zhong-Chen based on BSPDI. To quantify the traditional chinese medicine (TCM) pulse diagnosis in the future, we make pulse detection more accuracy after we establish the depth definition of TPNI. By this way, we can establish a practical clinical database and continue the research of quantification of TCM pulse diagnosis and have a great revolution in TCM.
