Arterial pulsation waveform has been considered as fundamental indicators in the diagnosis of cardiovascular disease and guide therapeutic decision in complex clinical situations. Abnormality of shapes and frequencies of palpation are symbols of certain cardiovascular disorders, thus how to pick up arterial pulse waveforms without distortion has become an important issue in biomedical signal processing. On the other hand, pulse diagnosis is the one of four kind diagnosis methods to determine the physiological condition of patients in Traditional Chinese Medicine (TCM). In clinic, most popular methods applied to measure pulse behavior include stethoscope, sphygmomanometer, and Doppler-based instrumentation. In TCM, most studies of pulse diagnosis machine use other devices to record pulse changes. A set of three pressure transducers to sense three location pulses has been proposed. Lu and Wang analyzed the harmonics from the frequency spectrum of pulse waves and related some illness condition to certain harmonics. The devices used in these studies could either interfere in the measurement because contacting or cost more as having additional sensors for multiple points probing. No touch pulse measurement with optical interferometer was proposed by Hong et.al, it can estimate skin vibration velocity. Echo-metric techniques which would make use of time-of-flight measurements of an energy pulse reflected from points on the object are not practical at short rangers due to very short time intervals that have to be measured. An optical non-contacting technology, which based on optical triangulation, is proposed in this study. Optical triangulation is well known in thickness and contour measurement, and applied to many industrial fields. This study will conduct the design of the pulse measurement system and verify the pulse measurement accuracy, then using this pulse measurement system to build a complete data base by measuring the patients. Moire’ will be used to locate the top of the pulse, then the vibration and frequency of the pulse will be record with this IR laser pulse measurement. 研究期間：9508 ~ 9512 |
