On the use of block matching for the estimation of arterial wall motion

2008 8th IEEE International Conference on BioInformatics and BioEngineering, 2008

Motion of the carotid artery wall is important for the quantification of arterial elasticity and contractility and can be estimated from sequences of B-mode ultrasound images. In the relatively few studies on the subject, block matching has been used to estimate displacements of selected areas of the arterial wall and of the atheromatous plaque. In this paper, we attempted a ...


Noninvasive strain imaging in pulsating vessels using beam steered ultrasound acquisitions

2011 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2011

Strain in the arterial wall can be estimated by cross-correlation of radiofrequency ultrasound data recorded at various blood pressure levels. Intravascular studies revealed a high correlation between high radial strain regions and plaque vulnerability in coronary arteries. A noninvasive variant of the technique is desired, since it will enable early screening for rupture prone plaques, also in asymptomatic populations. Recently, ...


Carotid artery wall dynamics captured with multi-plane high-frame-rate imaging

2015 IEEE International Ultrasonics Symposium (IUS), 2015

Plaques within the carotid artery show different dynamic behavior during fast pressure waves that propagate along the wall. These dynamic tissue-wave interactions can be captured in a longitudinal view of the carotid artery using high-frame-rate ultrasound imaging. A major disadvantage of this approach is that out-of-plane motion causes misinterpretation of the true wall motion. Here we describe a new imaging ...

  • On the use of block matching for the estimation of arterial wall motion

    Motion of the carotid artery wall is important for the quantification of arterial elasticity and contractility and can be estimated from sequences of B-mode ultrasound images. In the relatively few studies on the subject, block matching has been used to estimate displacements of selected areas of the arterial wall and of the atheromatous plaque. In this paper, we attempted a small study on the use and performance of three variations of block matching, namely forward-, backward- and combination-block-matching, in terms of estimating arterial wall motion. Simulated ultrasound image sequences, generated using (a) FIELD-II, an ultrasound simulation package and (b) a mathematical model of arterial wall displacement, were used. The warping index, defined as the mean geometric error in pixels between the true and recovered deformation, was used to evaluate the performance of the block matching techniques. Reasonably high values were obtained for all three cases; specifically, the warping index was 1.879 for forward-, 0.984 for backward- and 1.122 for combined block matching. In conclusion, block matching techniques are appropriate for estimating arterial wall motion from sequences of ultrasound images; backward tracking may be the preferred technique in such applications.

  • Noninvasive strain imaging in pulsating vessels using beam steered ultrasound acquisitions

    Strain in the arterial wall can be estimated by cross-correlation of radiofrequency ultrasound data recorded at various blood pressure levels. Intravascular studies revealed a high correlation between high radial strain regions and plaque vulnerability in coronary arteries. A noninvasive variant of the technique is desired, since it will enable early screening for rupture prone plaques, also in asymptomatic populations. Recently, we have shown that it is possible to obtain more precise radial (and circumferential) strain estimates by combining data from multiple beam steered ultrasound acquisitions in phantoms. However, the multi-angle method was tested using quasi-static data only, thus no motion artifacts were present. This study investigates the performance of the multi-angle method for pulsating vessels. Results are presented for a periodically pulsating vessel mimicking phantom and in vivo recordings of a healthy carotid artery. It is shown that the multi-angle technique also outperforms conventional single angle strain imaging for pulsating vessels.

  • Carotid artery wall dynamics captured with multi-plane high-frame-rate imaging

    Plaques within the carotid artery show different dynamic behavior during fast pressure waves that propagate along the wall. These dynamic tissue-wave interactions can be captured in a longitudinal view of the carotid artery using high-frame-rate ultrasound imaging. A major disadvantage of this approach is that out-of-plane motion causes misinterpretation of the true wall motion. Here we describe a new imaging setup comprising three resp. two intersecting high-frame-rate imaging planes. Using this multi-plane imaging setup we are now, for the first time, able to capture velocities along the carotid artery wall with high temporal resolution in multiple planes simultaneously.

  • Real-time simultaneous assessment of wall distension and wall shear rate in carotid arteries

    A novel ultrasound (US) system has been developed to make possible the real- time assessment of both blood velocity profile and wall displacements in human arteries. The system consists of a modified US machine and a custom PC add-on board based on a high-speed DSP board. The software has been customized to make possible the simultaneous selection of two independent M-lines. In the B-mode display. With respect to the artery of interest, such lines can be set at optimal angles for wall detection and blood velocity detection, respectively. When switched to PW-mode, the system fires the elements of the linear array probe in such a way that US bursts are alternatively transmitted into one of the two selected M-line directions. Quadrature demodulated echo signals produced along both such lines are sent to the DSP board, which allows the corresponding blood velocity profile and wall displacement (or distension) waveforms to be calculated and displayed in real-time. From the velocity profile, the wall shear rate (WSR), i.e. the spatial velocity gradient close to the blood-wall interface, is extracted. The system has been preliminarily tested in the common carotid arteries of 11 healthy volunteers. Results of simultaneous diameter distension and WSR measurements are reported.

  • Parametric analysis of velocity fields in the region of a modeled carotid artery stenosis

    Basic velocity measurements from a previously reported study of modeled carotid artery bifurcation disease are postprocessed to derive indices potentially useful for clinical diagnosis. Selected parameters are based upon ultrasound pulse Doppler velocity measurements made at sites +or-0.625 radius at axial distances of 0, 1, 3, 5, and 10 diameters downstream of smooth axially symmetric constrictions of 0%, 20%, 40%, 60%, and 80% diameter reduction.<>

  • Cardiovascular Oscillations of the Carotid Artery Assessed by Magnetoelastic Skin Curvature Sensor

    The present study concerns the nondisturbing assessment of cardiovascular oscillations of the carotid artery using a novel skin curvature sensor on the neck. The mechanical oscillations of the skin reflect changes of the artery radius and thus relevant physiological data such as cardiac and respiratory activities, their mutual dependencies, and even changes of blood pressure. The skin curvature sensor is easy to handle and it minimally disturbs the patient, which is relevant for many medical areas such as sleep monitoring.

  • System for estimating sclerosis of in vivo arteries based on ultrasound B-mode image analysis

    A new system has been developed for estimating hardening of the carotid artery by B-mode (Brightness-mode) image analysis. The method is based on in vivo stiffness, Eth, calculated from the variation of carotid-duct-diameter with changing of systolic and diastolic blood pressures. In addition from the results of tensile and internal pressure tests using in vitro human and animal arteries specimens, we found a correlation between Eth estimated from radial bulge of artery and mechanical tensile strength. Thus, using a correlation curve a technique for estimating in vivo Eth as well as tensile strength of carotid artery can be predicted. Then, to be a simple routine medical examination, a prototype software was developed, which is capable to measure the diameter changes by the image processing based on 30-image/s and one pixel size data (in case of the report, 0.0713 mm/pixel) of an ultrasound device. The total examination time for both sides of the common carotid arteries was within 300 seconds. To examine the validity of this technique, some clinical data were also shown. The result indicated that the stiffness Eth, strength, and critical burst pressure are useful symptom indices for arterial sclerosis, especially for finding the beginning sclerosis that would start early twenties.

  • Examination of IMT on the overall segment of the common carotid artery

    The arteriosclerosis is increasing an aging or varying our life style in Japan. The arteriosclerosis of the common carotid artery is diagnosed using intima-media thickness (IMT) which is obtained from echocardiogram. Up to the present, some methods of IMT measurement have been proposed. So, obtained IMT cannot represent properties of common carotid artery but except the only one measured point. And, measurements of IMT are defined as the average distance of interface between vessel tissue layers. In this paper, we measure IMT on the overall common carotid artery, and examine their variance comparing the normal subject with arteriosclerosis.

  • Effects of Puerarin on Monoamino Neurotransmitter Levels in the Striatum of Cerebral Ischemia Rats

    This study was undertaken to examine the patterns of changes in extracellular fluid (ECF) dopamine (DA), orepinephrine (NE) and serotonin (5-HT) in the striatum of rats with middle cerebral artery occlusion (MCAO). The effect of Puerarin on monoamine neurotransmitter in the MCAO rats was also studied. Methods: Microdialysis was used to sample the brains extracellular space during 80 min of cerebral ischemia followed by 80 min of reperfusion. The microdialysate was measured by high performed liquid chromatography (HPLC). Results: It showed Puerarin could alleviate cerebral ischemia damage.
