A Non-invasive Evaluation System for Pulmonary Artery Pressure and its Application Value

Wang Weiqi,Chen Shubao,Wang Yuanyuan,Liu Bin,Zhang Yuqi,Yu Jianguo,Sun Kun,Chen Sizhong

Strategic Study of CAE 2000, Volume 2, Issue 1,   Pages 41-46

Abstract:

Pulmonary artery pressure is an important parameter for clinical diagnosis and physiological research. It used to be measured by the traditional invasive method, cardiac catheterization. A non-invasive method based on audio pulsed-wave Doppler signal and ECG is presented and the noninvasive evaluation system is developed. The key techniques, animal experiment and clinical probation are described in this paper. The key techniques include： wavelet de-noising, new percentile method as well as locating characteristic point with wavelet. According to the data obtained from animal experiments of 9 dogs and 60 cases, the relativity with cardiac catheterization exceeds 80% .

Development of surface reconstruction algorithms for optical interferometric measurement

Dongxu WU, Fengzhou FANG

Frontiers of Mechanical Engineering 2021, Volume 16, Issue 1,   Pages 1-31 doi: 10.1007/s11465-020-0602-6

Abstract: Optical interferometry is a powerful tool for measuring and characterizing areal surface topography in precision manufacturing. A variety of instruments based on optical interferometry have been developed to meet the measurement needs in various applications, but the existing techniques are simply not enough to meet the ever-increasing requirements in terms of accuracy, speed, robustness, and dynamic range, especially in on-line or on-machine conditions. This paper provides an in-depth perspective of surface topography reconstruction for optical interferometric measurements. Principles, configurations, and applications of typical optical interferometers with different capabilities and limitations are presented. Theoretical background and recent advances of fringe analysis algorithms, including coherence peak sensing and phase-shifting algorithm, are summarized. The new developments in measurement accuracy and repeatability, noise resistance, self-calibration ability, and computational efficiency are discussed. This paper also presents the new challenges that optical interferometry techniques are facing in surface topography measurement. To address these challenges, advanced techniques in image stitching, on-machine measurement, intelligent sampling, parallel computing, and deep learning are explored to improve the functional performance of optical interferometry in future manufacturing metrology.
