The microfabricated sensor is constructed using silicon carbide as the substrate and aluminum nitride (AlN) as the piezoelectric film. The piezoelectric coefficient (d33) of AlN is measured using piezoresponse force microscopy as 3.62 pm/V. The sensor exhibits an impedance response of ∼1kΩ in the 100 kHz to 300 kHz frequency range, which is below the input impedance of conventional AE systems, causing a slight reduction in amplitude. Following the sensitivity and impedance characterizations, the sensor is tested inside a furnace at temperatures ranging from room temperature up to 650◦C. Pencil lead break and ball drop tests are used to simulate AE sources. The sensor is dry-coupled to the test surface using high-temperature wires and a stainless-steel fixture. The sensor sensitivity decreases slightly with increasing temperature, with a maximum reduction of 6 dB at 650◦C. The sensor is evaluated for detecting creep damage in 316L stainless steel and demonstrated performance comparable to conventional sensors attached with waveguides. Compared with conventional bulk AE sensors, the key characteristics of this AlN-based thin-film AE sensor are its high-temperature functionality and couplant-free attachment, enabling direct placement near critical systems under elevated temperatures. This positioning mitigates the influences of long wave paths introduced by waveguides, enhancing the sensor's effectiveness in detecting the initiation and progression of damage. The developed sensor leverages the advantages of microfabrication, offering benefits such as mass production, low cost, and a compact footprint.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143572276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accuracy of MB localization is critical for producing high-quality images, which makes tissue clutter filtering an essential step in ULM. Recent advances in deep learning have led to innovative methods for tissue clutter filtering, particularly those based on 3D convolution, which effectively capture the spatiotemporal features of MBs. These methods significantly improve upon traditional approaches by addressing issues such as lengthy inference time and limited flexibility. However, many deep learning techniques primarily focus on B-mode images and demonstrate lower efficiency. To overcome these limitations, this study proposes knowledge distillation for tissue clutter filtering to enhance filtering efficiency while maintaining performance. This study first develops a lightweight 2D complex-valued CNN (CL-UNet) as the teacher model, utilizing I/Q signal input. Subsequently, a 2D real-valued CNN (UNet-T) is developed as the student model, which uses envelope data as input. Feature-based knowledge distillation is applied to transfer knowledge from the teacher model to the student model (Guided UNet-T). All models are trained on simulated data and fine-tuned on in vivo data. The experimental results show that CL-UNet (I/Q, ours) demonstrates better filtering performance compared to the B-mode image-based approach on both simulated and in vivo data. Guided UNet-T outperforms both Singular Value Decomposition (SVD) and Random SVD (RSVD) in terms of both performance and speed, offering the best balance between filtering efficiency and effectiveness.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143541858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SAW) resonator on the 42°YX-LiTaO3/SiO2/Si structure. The full three-dimensional (3D) finite element method (FEM) is applied with the assistance of the hierarchical cascading technique. Excellent agreement is obtained between calculation and measurement not only for the effective electromechanical coupling factor keff2 but also the Bode Q without inclusion of empirical loss mechanisms. Behavior of calculated Bode Q is mostly governed by the number of IDT finger pairs NI and aperture length W. SAW field distribution is derived from the FEM result. Oblique SAW leakage is observed in the busbar region of reflectors and becomes negligible when NI is large. From this, it is concluded that the Bode Q reduction discussed here is mainly occurred by the oblique SAW leakage caused by the in-plane diffraction. Finally, the mBVD model is applied for quantitative characterization. It is shown that the in-plane SAW diffraction can be modelled well by the mBVD model and gives significant impact only to the anti-resonance Q. Surprisingly its loss is dominant even when NI=100.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143556750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It involves hydrophone measurements of the 2-D distribution of acoustic pressure waveforms in a transverse plane in front of the transducer - a hologram - and subsequent numerical forward or backward projection of the ultrasound field. This approach enables full spatiotemporal reconstruction of the acoustic field, including the vibrational velocity at the transducer surface. This allows identification of transducer defects as well as structural details of the radiated acoustic field such as side lobes and hot spots. However, numerical projections may be time-consuming (1010 - 1011 operations with complex exponents). Moreover, back-projection from the measurement plane to the transducer surface is sensitive to misalignment between the axes of the positioning system and the axes associated with the transducer. This paper presents an open access transducer characterization toolbox for use in MATLAB or Octave on Windows computers (https://github.com/pavrosni/xDDx/releases). The core algorithm is based on the Rayleigh integral implemented in C++ executables for graphics and central processing units (GPUs and CPUs). The toolbox includes an automated procedure for correcting axes misalignments to optimize the visualization of transducer surface vibrations. Beyond using measured holograms, the toolbox can also simulate the fields radiated by user-defined transducers. Measurements from two focused 1.25-MHz 12-element sector transducers (apertures of 87 mm, focal distances of 65 mm and 87 mm) were used with the toolbox for demonstration purposes. Simulation speed tests for different computational devices showed a range of 0.2 s - 3 min for GPUs and 1.6 s - 57 min for CPUs.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143541895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, enhancing image quality in PWI has necessitated an increase in the number of plane waves, unfortunately compromising its hallmark high frame rates. To fully leverage the frame rate advantage of PWI, existing deep-learning-based methods often employ single-plane wave (PW) as the sole input for training strategies to replicate multi-PWs compounding results. However, these typically fail to capture the intricate information provided by steered waves. In response, we have developed a sophisticated architecture that implicitly integrates multi-angle information by generating and dynamically combining virtual steered plane waves within the network. Employing deep learning techniques, this system creates virtual steered waves from the single primary input view, simulating a limited number of steering angles. These virtual PWs are then expertly merged with actual single PW data through an advanced attention mechanism. Through implicit multi-angle acoustic synthesis, our approach achieves the high-quality output typically associated with extensive multi-angle compounding. Rigorously evaluated on datasets acquired from simulations, experimental phantoms, and in vivo targets, our method has demonstrated superior performance over traditional single-plane wave strategies by providing more stable, reliable, and robust imaging outcomes. It excels in restoring detailed speckle patterns and diagnostic characteristics crucial for in vivo imaging, thereby offering a promising advancement in PWI technology without sacrificing speed.

Existing multi-particle manipulation techniques are usually realized by precisely designing the incident wave's phase distribution to synthesize a complex and steady-state acoustic field containing multiple acoustic trapping beams. However, interference effects between multiple beams tend to produce artifacts that trap particles in unwanted positions, limiting accuracy and the number of manipulated particles. In addition, those techniques can only holistically manipulate multiple particles, namely lacking parallel working ability. In this study, we proposed a time-sharing acoustic tweezers method to achieve the manipulation of multiple particles by rapidly switching individual trapping beams, minimizing interference artifacts. We applied this method to a 256-element phased-array acoustic tweezer system with designed ultrasonic pulse sequences to synthesize a single focused, twin trap, and vortex beam, enabling the pseudo-parallel manipulation of multiple particles in three-dimensional space at a beam switching frequency of ≥ 10 kHz. The experiments on polydimethylsiloxane particles ranging from micrometers to millimeters in diameter demonstrated that up to 96 particles can be successfully trapped and assembled into a two-dimensional lattice. Different numbers of particles were also patterned into dynamic contours, such as sinusoidal vibration (10 particles) and butterfly flapping (24 particles). Additionally, the trapped multiple particles also can be rotated around their respective orbits. The proposed technique improved the number of objects dynamically manipulated in a parallel manner, advancing holographic acoustic tweezers and their applications.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143541857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, there are methods that can map wave fields remotely or locally. However, there are limitations with these methods. For example, when mapping the wave fields remotely, the spatial resolution is limited due to a poor diffractionlimited resolution of the receiver, especially when the f-number of the receiver is large. To map the wave fields locally, the receiver is either subject to damage in hazardous environments (corrosive media, high temperature, and high wave intensity, etc) or difficult to be placed inside an object. To address these limitations, in this paper, the PSF-modulation super-resolution imaging method (January, 2024 IEEE TUFFC) was applied to map pulse ultrasound wave fields remotely at a high spatial resolution, overcoming the diffraction limit of a focused receiver. For example, to map a pulse ultrasound field of a full-width-at-half-maximum (FWHM) beam width of 1.24 mm at the focal distance of a transmitter, the FWHM beam widths of the super-resolution mapping of the pulse wave field with a spherical glass modulator of 0.7-mm diameter at two receiver angles (0° and 45°) were about 1.13 mm and 1.22 mm respectively, which were close to the theoretical value of 1.24 mm and were much smaller than the diffraction-limited resolution (1.81 mm) of the receiver. Without using the super-resolution method to remotely map the same pulse wave field, the FWHM beam width was about 2.06 mm. For comparison, the FWHM beam width obtained with a broadband (1-20 MHz) and 0.6-mm diameter polyvinylidene fluoride (PVDF) needle hydrophone was about 1.41 mm. In addition to the focused pulse ultrasound wave field, a pulse Bessel beam near the transducer surface was mapped remotely with the super-resolution method, which revealed high spatial frequency components of the beam.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143541851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
