Résumé :
Ultrasonic multi-angle plane-wave (PW) coherent compounding relies on delay-and-sum (DAS) beamforming of two-dimensional (2D) echo matrix in both the dimensions PW transmit angle and receiving channel to construct each image pixel. Due to the characteristics of DAS beamforming, PW coherent compounding may suffer from high image clutter when the number of transmit angles is kept low for ultrafast image acquisition. Delay-multiply-and-sum (DMAS) beamforming exploits the spatial coherence of the receiving aperture to suppress clutter interference. Previous attempts to introduce DMAS beamforming into multi-angle PW imaging has been reported but only in either dimension of the 2D echo matrix. In this study, a novel DMAS operation is proposed to extract the 2D spatial coherence of echo matrix for further improvement of image quality. The proposed 2D-DMAS method relies on a flexibly tunable p value to manipulate the signal coherence in the beamforming output. For p = 2.0 as an example, simulation results indicate that 2D-DMAS outperforms other one-dimensional DMAS methods by at least 9.3 dB in terms of ghost-artifact suppression. Experimental results also show that 2D-DMAS provides the highest improvement in lateral resolution by 32% and in image contrast by 15.6 dB relative to conventional 2D-DAS beamforming. Nonetheless, since 2D-DMAS emphasizes signal coherence more than its one-dimensional DMAS counterparts, it suffers from the most elevated speckle variation and the granular pattern in the tissue background.

Résumé :
In this study, we present a united sign coherence factor beamformer for coherent plane-wave compounding (CPWC). CPWC is capable of reaching an image quality comparable to the conventional B-mode with a much higher frame rate. Conventional coherence factor (CF) based beamformers for CPWC are based on one-dimensional (1D) frameworks, either in the spatial coherence dimension or angular coherence dimension. Both 1D frameworks do not take into account the coherence information of the dimensions of each other. In order to take full advantage of the radio-frequency (RF) data, this paper proposes a united framework containing both spatial and angular information for CPWC. A united sign coherence factor beamformer (uSCF), which combines the conventional sign coherence factor (SCF) and the united framework, is introduced in the paper as well. The proposed beamformer is compared with the conventional 1D SCF beamformers (spatial and angular dimension beamformers) using simulation, phantom and in vivo studies. In the in vivo images, the proposed method improves the contrast ratio (CR) and generalized contrast-to-noise ratio (gCNR) by 197% and 20% over CPWC. Compared with other 1D methods, uSCF also shows an improved contrast and lateral resolution on all datasets.

Résumé :
The recently introduced plane-wave compounding method based on multiple plane-wave excitation has enabled several new applications due to its high frame rate (>1000 Hz). In this paper, a new efficient transmit delay calculation method in plane-wave compound imaging for a curved array transducer is presented. In the proposed method, the transmit delay is only calculated for a steering angle of 0° and is shifted along the element of the transducer to obtain other transmit delays for different steering angles. To evaluate the performance of the proposed method, the computational complexity was measured for various transmission conditions. For the number of elements and plane-wave excitations of 128 and 65, respectively, the number of operations was substantially decreased in the proposed method compared with the conventional method (256 vs. 8320). The benefits of the proposed method were demonstrated with phantom and in vivo experiments, where coherent plane-wave compounding with 65 excitations provided larger CR and CNR values compared to nine excitations (−22.5 dB and 2.7 vs. −11.3 dB and 1.9, respectively). These results indicate the proposed method can effectively reduce the computational complexity for plane-wave compound imaging in curved array transducers.

Résumé :
In this work, in the process of plane-wave ultrasound probing from different angles the attainable spatial resolution was estimated on the basis of the previously developed theory of the Doppler response formation. In the theoretical calculations coherent compounding of the Doppler response signals was conducted over the period of changing the steering angles of probing. For this case an analytical expression for the ultrasound system sensitivity function over the field, which corresponds to the point spread function, is obtained. In the case of a rectangular weighting window for the response signals, the resolution is determined by the well-known sinc-function. The magnitude of the lateral resolution is inversely proportional to the range of the steering angles. It is shown that the theoretically estimated magnitude of the Doppler system lateral resolution, when using the technique of coherent plane-wave compounding, is in good agreement with the experimental data presented in literature.

Résumé :
Coherent plane-wave compounding is the coherent summation of several successive plane waves incident at different angles. This thesis presents results from simulations and in vitro and in vivo measurements of stationary and moving objects, with focus on loss of resolution and contrast due to object motion. Resolution and contrast results for several angle selections, angle sequences and object velocities with and without motion correction have been compared.It is shown that using a subset of plane-wave tilt angles by decimating the optimal selection introduces grating lobes which degrades the image contrast, while imaging with a lower maximum tilt angle degrades the lateral resolution. The contrast loss for decimation factor 2 was more significant for simulations than for in vitro measurements. While the contrast went from -40 to -30 dB for the simulations, a decimation factor of 4 was needed to degrade the contrast significantly for the measurements. Decimating the angle selection by a factor of 2 doubles the achievable frame rate. A reduction in maximum angle from 13.7 to 8.2 deg., which corresponds to an increase in transmit F-number from 2.1 to 3.5, gives less than 0.3 mm degradation of lateral resolution. The lateral resolution is of the order of 1 mm. This reduction in maximum angle increases the frame rate by a factor of 1.2.Axial point scatterer velocity leads to considerably worse image quality than for stationary scatterers, while the effect of lateral scatterer velocities is limited. The degree of contrast and resolution loss due to object motion is dependent on the selection of plane waves which constitute a frame, and the sequence in which the plane waves are transmitted. Using a subset of the optimal angle selection leads to improvement in image quality for an axial velocity of 10.0 cm/s for decimation factor 4, but not for decimation factor 2, even though the total scatterer movement per frame is reduced by the reduction of transmitted plane-waves. The loss of quality due to motion was less for fewer tilt angles, but the total image quality was still worse for many of these sets of angles due to grating lobes.The unwanted effects of motion for in vivo-measurements were not seen to the same extent as for simulated point scatterers, and working with the coherent plane-wave compound seems promising for moving objects.

Recently, ultrasound imaging with coherent plane wave compounding has played an important role in high-quality ultrafast imaging and shear wave elastography, leveraging multiple angled plane-wave emissions. In this study, we propose an angle selection strategy for ultrasound imaging with coherent plane wave compounding (CPWC), featuring lower grating-lobe and ghost artifacts while fewer angled plane-wave emissions are required compared to commonly used equal-angular-spacing decimation in the angle sequence (EAS-CPWC). In our strategy, the relation between conventional synthetic transmit aperture imaging and CPWC is discovered. Given the number of the total tilted plane-wave excitations, with our angle selection strategy, the synthesized effective aperture by the CPWC approximates to the desired two-way effective aperture with an appropriate width, element spacing, and shape; thus enabling grating-lobe and ghost artifacts suppression. Field II simulations and experiments on wire, anechoic cyst phantoms and the ex vivo porcine artery were performed to verify our angle-selection strategy. Simulation and experimental results showed that with our proposed angle sequence, the grating-lobe and ghost artifacts were suppressed by 5 dB and 15 dB respectively, and 25 ± 5 % contrast-to noise ratio (CNR) improvement was achieved. Overall, we demonstrated the efficacy of our proposed angle sequence for grating-lobe and ghost artifacts suppression.

Résumé :
Typical ultrafast plane-wave ultrasound imaging involves: 1) insonifying the medium with several plane-wave pulses emitted at different angles by a linear transducer array, 2) sampling the returning echo signals, after each plane-wave emission, with the same transducer array, 3) beamforming the recorded angle-specific raw data frames, and 4) compounding the beamformed data frames over all angles to form a final image. This thesis attempts to address the following question: Given a set of available plane-wave emission angles, which ones should we select for acquisition (i.e., which angle-specific raw data frames should we sample), to achieve adequate image quality at low cost associated with both sampling and computation? We propose a simple similarity-driven angle selection scheme and evaluate its several variants that rely on user-specified similarity measurement thresholds guiding the recursive angle selection process. Our results show that the proposed scheme has a low computational overhead and can yield significant savings in terms of the amount of sampled raw data.

In this paper, we study the feasibility of high-frequency ultrafast ultrasound systems through the simulation of coherent plane-wave compounding technology in high-frequency. Ultrafast imaging system can reach the physical limits of ultrasound, which is up to the level of thousands of frame rate. In this case, it is possible to observe more subtle part, this is impossible to do the conventional ultrasound system. Therefore breakthrough imaging mode ultrasound images quickly and more widely in the application, such as: tissue imaging, flow imaging, micro-bubbles, and even neurological applications. Ultrafast imaging systems currently available composite plane wave technology cannot provide studies using high-frequency ultrasound for small animal studies and other minor skin or eye tissue, its imaging systems cannot provide adequate analytical capacity. The lateral resolution in 40MHz ultrasound using coherent plane-wave compounding method can be evaluate up to 67μm and contrast is 56.41dB. It is a significant improvement to the single plane wave imaging with low spatial resolution and low contrast. The frame rate of 35 plane-wave compound method can reach the limitation of elastatography and maintain the lateral resolution in 69μm and contrast in 52.84dB. In the future this study provides the realization of high-frequency ultrasound ultrafast imaging of hardware architecture and a hardware design specifications. The results of the simulation also can be used as high-frequency ultrasound ultrafast imaging system of reference.

Résumé :
Ultrafast plane-wave ultrasound imaging offers very high frame rates (exceeding thousands of frames per second) but entails large volumes of backscattered data collected by a sensor array over multiple plane-wave emissions at different angles. We propose a simple method for reducing the total amount of sampled data. First, we acquire the zero-angle data in full, and then we perform deterministic subsampling of the remaining nonzero-angle data. Our subsampling patterns are angle-specific and derived based on the zero-angle data using a Fourier-domain migration technique. We use two experimental datasets to evaluate the benefits and drawbacks of our proposed method in terms of spatial resolution and contrast-to-noise ratio, observed in the resulting B-mode images.

Doppler technique is commonly used in medical ultrasound system. However, conventional Doppler is limited by the flow angle and the maximum detectable velocity. This research was designed to combine the high frame rate imaging system and the speckle tracking technique to provide accurate estimation of the vector velocity. The high accuracy of speckle tracking technique depends on high image quality and high frame rate. In this study, we investigate the coherent plane wave compounding imaging approach (CPWC) to improve the efficacy of blood velocity estimation in speckle tracking technique. In plane wave excitation, the ultrasound is not focused during the transmissions to increase the frame rate at the cost of degraded image quality. By compounding coherently the images obtained with several plane waves with different angles, both the image quality and SNR can be improved. It is also combined with the recursive technique to reduce the acquisition time by providing several high resolution images with different features for speckle tracking. This will benefit the estimation accuracy in flow imaging and elastography. Moreover, the continuous flow image data will also help the design of the wall filter to separate the blood flow from tissue. The result in this study indicates that the STD and BIAS performance of the lateral velocity component tracking of CPWC in any Doppler angles is better than Single plane wave excitation approach (SPWE). The STD performance of the lateral velocity component tracking will decrease while the axial velocity component increases. Although the STD performance of the axial velocity component tracking of CPWC in any Doppler angles is still better than SPWE, the BIAS performance is inferior due to the point-spread-function shift by the axial movement of the imaged target. At the same time, the BIAS performance will decrease while the axial velocity component increases between the compounded images.

In recent years, inspired by ultrasound ultrafast imaging, plane wave emission technique has been widely utilized in ultrasound images. The traditional emission focus image is focused on the region of interest, with the different location and depth. The plane wave emission technique emits a plane wave and spread to the range of interest, a wide range of imaging is quickly obtained. The images obtained by plane wave are fast, but the effects of side lobes, grating lobes and speckle noise are sacrificed the image contrast. The plane wave emission technique can be used to coherent sum with different angles to achieve to improve the image spatial resolution. Although coherent sum can effectively improve the image resolution by suppressing the artifacts, the corresponding image contrast-to-noise (CNR) is still limited. Therefore, in this study uses the plane wave based ultrasound ultrafast angle compounding combined with coherent factor weighting to enhance the image contrast. Results indicate that, plane wave emission angle and receiver weighting function of the same angle, the CNR has the peak value. In simulation, the CNR can be increased by 73%, the experimental part of the CNR can be improved by 110%. Through the coherent factor weighting and angle compounding technology, can make the plane wave image to maintain the image smoothness while improving the image contrast.

Résumé :
Coherent plane-wave compounding (CPWC) ultrasound is an important modality enabling ultrafast biomedical imaging. To perform CWPC image reconstruction for a stratified (horizontally layered) medium, one needs to know how the speed of sound (SOS) varies with the propagation depth. Incorrect sound speed and layer thickness assumptions can cause focusing errors, degraded spatial resolution and significant geometrical distortions resulting in poor image reconstruction. We aim to determine the speed of sound and thickness values for each horizontal layer to accurately locate the recorded reflection events to their true locations within the medium. Our CPWC image reconstruction process is based on phase-shift migration (PSM) that requires the user to specify the speed of sound and thickness of each layer in advance. Prior to performing phase-shift migration (one layer at a time, starting from the surface), we first estimate the speed of sound values of a given layer using a cosine similarity metric, based on the data obtained by a multi-element transducer array for two different plane-wave emission angles. Then, we use our speed estimate to identify the layer thickness via end-of-layer boundary detection. A low-cost alternative that obtains reconstructed images with fewer phase shifts (i.e., fewer complex multiplications) using a spectral energy threshold is also proposed in this thesis. Our evaluation results, based on the CPWC imaging simulation of a three-layer medium, show that our sound speed and layer thickness estimates are within 4% of their true values (i.e., those used to generate simulated data). We have also confirmed the accuracy of our speed and layer thickness estimation separately, using two experimental datasets representing two special cases. For speed estimation, we used a CPWC imaging dataset for a constant-speed (i.e., single-layer) medium, yielding estimates within 1% of their true values. For layer thickness estimation, we used a monostatic (i.e., single-element) synthetic-aperture (SA) imaging dataset of the three-layer medium, also yielding estimates within 1% of their true values. Our evaluation results for the low-cost alternative showed a 93% reduction in complex multiplications for the three-layer CPWC imaging dataset and 76% for the three-layer monostatic SA imaging dataset, producing images nearly similar to those obtained using the original PSM methods.

The problem of coherent reflecton of an acoustic plane wave from a random seabed consisting of a randomly inhomogeneous sediment layer overlying a uniform elastic sea floor is considered in this analysis. The random perturbation in the sediment layer is attributable to the sound-speed variations, resulting in volume scattering due to medium inhomogenieties. An approach based upon perturbation theory, combining with a derived Green's function for a slab bounded above and below respectively by a fluid and an elastic half space ,is employed to obtain an analytic solution for the coherent field in the sediment layer. A linear system is then constructed to facilitate the analysis of the coherent reflection field. The results of the coherent reflection coefficient for various sediment randomness, frequency , sediment thickness, and sea floor elasticity have been numerically generated and analyzed. It was found that the higher/larger size of randomness , frequency, thickness, and shear-wave speed, the lower the coherent reflection. Physical interpretation for the characteristics of various results were provided.

Résumé :
AbstractWhen Otto Stern embarked on molecular-beam experiments in his new lab at Hamburg University a century ago, one of his interests was to demonstrate the wave-nature of atoms and molecules that had been predicted shortly before by Louis de Broglie. As the effects of diffraction and interference provide conclusive evidence for wave-type behavior, Otto Stern and his coworkers conceived two matter-wave diffraction experiments employing their innovative molecular-beam method. The first concept assumed the molecular ray to coherently scatter off a plane ruled grating at grazing incidence conditions, while the second one was based on the coherent scattering from a cleaved crystal surface. The latter concept allowed Stern and his associates to demonstrate the wave behavior of atoms and molecules and to validate de Broglie’s formula. The former experiment, however, fell short of providing evidence for diffraction of matter waves. It was not until 2007 that the grating diffraction experiment was retried with a modern molecular-beam apparatus. Fully resolved matter-wave diffraction patterns were observed, confirming the viability of Otto Stern’s experimental concept. The correct explanation of the experiment accounts for quantum reflection, another wave effect incompatible with the particle picture, which was not foreseen by Stern and his contemporaries.

Résumé :
This chapter continues with a study of the time independent Schrödinger equation and seeks to contrast the quantum behavior of a free particle with that of a particle localized in a potential quantum well. A free particle can exist over all space or can be localized in a wave package. The wave packet is a coherent superposition of the plane waves that make up the wave function that localizes the particle because of constructive and destructive interference. The wave packet spreads out in time because the waves leading to constructive interference get out of phase. In Chapter 2, the particle was localized by a quadratic potential energy. Here, the potentials are described as piecewise constant. The approach is based on assuming a one-dimensional space, x, which is relevant to many problems in the laboratory. The solution is easily generalized to higher dimensions (x-y or x-y-z), but the physics remains the same. The objective is to understand the shape of the eigenfunctions in space and to be able to relate this to the probability density of locating the particle, as well as understanding the relevance of these systems to today’s technology.

Treating an imaging system as a linear system and use llinear system properties to d iscuss both coherent and incoherent imaging. Use a one dimensional pin hole camera to study the theory of incoherent imaging. Two different criteria, Rayleigh and Sparrow, are used to define the resolution limits of the camera. From the simple theory define the optical transfer function and the modulation transfer function as appropriate characterizations of complex imaging systems. A review of the human imaging system emphasizes tits idfferences with man made cameras. Coherent imaging is based on Abbe’s theory of microscopy. A simple 4f imaging system can be used to understand how spatial resolution is limited by the optical aperture and by controlling the aperture, we can enhance the edges of an image or remove noise intensity noise on a plane wave. Apodizing the aperture allows astronomers to locate planents orbiting distant stars.
