Cardiovascular disease is the leading cause of death in many developed countries. Arteries of people suffering from this disease become stiff and blocked by fatty deposits. In recent years, non-invasive imaging techniques have been playing an increasingly important role in detecting the development of cardiovascular disease. Several methods focus on the measurement of pulse wave velocity, the velocity at which the pressure wave propagates, because it is directly related to arterial stiffness. The objective of this project is to investigate the feasibility of measuring local pulse wave velocity from the blood flow waveforms acquired by Doppler ultrasound. The proposed method includes the following steps: first acquire flow waveforms by Doppler ultrasound at two locations within the same artery, next detect the delay or difference in arrival time of the flow wave at the two arterial locations, and then calculate the PWV by dividing the length of the arterial segment being imaged by the calculated time delay. Although at the conclusion of this study reliable pulse wave velocity detection is not achieved, the study sheds light on many important issues surrounding this potential application. The project explores how sources of variations such as radial positioning of the probe and noise level affect the accuracy of the delay estimate.

Full textThis work focuses on the processing of biomedical images. The aim of our study is to estimate the mechanical properties of the carotid artery in vivo using ultrasound imaging, in order to detect cardiovascular diseases at an early stage. Over the last decade, researchers have shown interest in studying artery wall motion, especially the motion of the carotid intima-media complex in order to demonstrate its significance as a marker of Atherosclerosis. However, despite recent progress, motion estimation of the carotid wall is still difficult, particularly in the longitudinal direction (direction parallel to the probe). The development of an innovative method for studying the movement of the carotid artery wall is the main motivation of this thesis. The three main contributions proposed in this work are i) the development, the validation, and the clinical evaluation of a novel method for 2D motion estimation of the carotid wall, ii) the development, the simulation and the experimental validation of the 3D extension of the estimation method proposed, and iii) the experimental evaluation of the 2D proposed method in ultra-fast imaging, for the estimation of the local pulse wave velocity. We propose a motion estimation method combining tagging of the ultrasound images, and a motion estimator based on the phase of the ultrasound images. The ultrasonic tagging is produced by means of transverse oscillations. We present two different approaches to introduce these transverses oscillations, a classic approach using a specific apodization function and a new approach based on filtering. The proposed motion estimator uses the 2D analytical phase of RF images using the Hahn approach. This thesis work shows that, compared with conventional methods, the proposed approach provides more accurate motion estimation in the longitudinal direction, and more generally in directions perpendicular to the beam axis. Also, the experimental evaluation of our method on ultra-fast images sequences from carotid phantom was used to validate our method regarding the estimation of the pulse wave velocity, the Young’s modulus of the vessels wall, and the propagation of a longitudinal movement

Full textРаботоспособность обсадных колонн - один из главных факторов, влияющих на производительность и безопасность работы скважины. Отказы элементов обсадных колонн проявляются как при спуске и креплении колонны, так и во время освоения скважины и, особенно, в процессе ее продолжительной (более 20 лет) эксплуатации. Бывают случаи, когда через аварии с обсадными колоннами ликвидируют скважины, не выполнившие своего целевого назначения. Особенно актуальны вопросы контроля обсадных колонн подземных хранилищ газа, глубоких скважин и скважин, которые продолжительное время были на консервации. Практическое значение полученных результатов состоит в том, что разработанные способы и средства контроля позволяют: обеспечить контроль технического состояния обсадных колонн непосредственно в скважине; повысить надежность работы глубинного устройства благодаря использованию невращающейся системы сканирования и уменьшить её габаритные размеры благодаря использованию только одного измерительного канала и одного преобразователя, что играет значительную роль при конструировании средств внутритрубного контроля.
Is shown and prove that most informative parameters, which responsible for operational reliability of casing strings and which determine their actual technical condition, are the geometrical parameters. According to theoretical and experimental researches the means of the acoustic testing of geometrical parameters of pipes from their internal side and methodology of application with this purpose an acoustic pulse-echo method of the testing in operational conditions of a well was developed. Dependence of a speed of longitudinal ultrasonic wave propagation in a material of casing string and sensitivity of an acoustic tract from the operational factors experimentally are investigated. The mathematical model of the testing (of a work of an acoustic tract and estimation of an acoustic field) in conditions of a well is developed. The complex of means of the acoustic testing of geometrical parameters of casing strings in a well is developed.

Full textThe acoustoelasticity theory relates the variation in propagation velocity of mechanical waves to the stress variation in a solid medium. In brittle materials such as concrete, damage affects the propagation velocity parallel to the acoustoelastic effect. This research aims to identify and quantify how damage and acoustoelastic effect act on Ultrasonic Pulse Velocity (UPV) in concrete samples subjected to uniaxial compression. In order to do so, three phases of testing were performed. The first one focused on generating data to analyze the application of the Coda Wave Interferometry (CWI). Two variations of this method were studied and compared, to the purpose of determining which variation shows better results and which parameters should be adopted in the analysis. To enable the analysis, a computational code using Python 3.6.0 language was developed. It was verified that the stretching technique shows better results than the traditional coda wave interferometry technique. The second phase was dedicated to study the variation in propagation velocity due to damage recovery in the sample. The third phase addressed the influence of the sample geometry and the concrete composition over the response from the material to the acoustoelasticity. Furthermore, a Damage Index (D) was defined based on the elastic modulus reduction due to loading, in order to isolate the variation of velocity due solely to the acoustoelastic effect. Regarding the study of damage recovery over time, the relative velocity variation in the first 24 hours following the withdrawal of the loading showed to be too little when compared to the variations caused by temperature and humidity conditions. It was also concluded that the cylindrical samples showed more uniform responses to the acoustoelastic effect than the prismatic samples. Finally, the Damage Index proved itself to be a reliable tool to isolate the effects of damage and acoustoelasticity over the UPV.
