脉诊是东方医学中一种重要且普遍使用的方法。由于传统的诊脉方法依赖于东方医学医生手指的主观感觉，因此一直需要更客观的脉诊方法。最近，已经开发出各种脉象分析仪以满足这种客观的诊脉和解读需求。然而，这些尝试大多未能成功取代东方医学医生用手指进行的诊脉。为了提高脉象分析仪的性能，除了提高重复性和再现性之外，还应该为文献中的脉象图像开发适合机器的解读方法。需要解读的广泛使用的脉象图像之一是浮脉和沉脉。浮脉和沉脉是两种具有代表性的脉象图像，它们告知我们应该施加多大的压力才能获得最大的脉象力度。先前的一项研究通过定义浮沉脉系数（CFS），为浮脉和沉脉提出了一种简便且统一的测量方法。我们发现，在某些情况下，CFS的原始定义可能存在错误。为了提高性能，我们引入了一种新的CFS算法，用于通过脉象分析仪（3 - D MAC）确定浮脉和沉脉。为了测试新提出算法的性能，我们进行了一项临床研究，比较了与东方医学医生浮脉和沉脉诊断的符合率。我们发现，在被诊断为有浮脉或沉脉的受试者中，新的CFS算法显示出55.3%的诊断率和73.0%的符合率，与原始CFS算法相比，诊断率和符合率分别提高了约3%和6%。
The pulse diagnosis is an important and universally used method in Oriental Medicine. Since the traditional method of palpating the pulse relies on the subjective sense in the fingers of an Oriental Medical Doctor(OMD), there has been continued need for more objective method for pulse diagnosis. Recently, various pulse analyzers have been developed to meet such objective palpation and interpretation. However, most of these attempts were not successful to replace OMD's own palpation by fingers. To improve the performance of the pulse analyzers, one should develop machine-appropriate interpretations for the pulse images in the literature, in addition to the improvement in the repeatability and reproducibility. One of such widely-used pulse images to be interpreted is the floating and sinking pulse. The floating and sinking pulses are the two representative pulse images informing us how strong pressure one should apply to obtain the maximal pulse strength. A previous study suggested a convenient and unified measure for the floating and sinking pulses by defining the coefficient of the floating-sinking pulse(CFS). We found the original definition of the CFS could be erroneous under some situations. To improve the performance, we introduce new CFS algorithm for determining the floating and sinking pulse with a pulse analyzers(3-D MAC). To test the performance of the newly suggested algorithm, we conducted a clinical study comparing the agreement ratio with the floating and sinking pulse diagnosis by the OMDs. We found that, among the subjects who are diagnosed with having either the floating pulse or sinking pulse, the new CFS algorithm showed 55.3% diagnosis rate and 73.0% concordance rate, which are about 3% and 6% improvement in the diagnosis rate and agreement rate, respectively, compared to the original CFS algorithm. ??????????????????????????????????????????????????????????????????????????????????????????????????????????????
