However, practical implementation remains challenging due to difficulties in reliably reproducing the micron-scale features required for MHz-frequency operation, and the lack of quality assurance processes linking design intent to fabricated performance. This work presents the evaluation of a 3D-printed acoustic isolator-type metamaterial (AI-MM) backing designed for MHz operation using a custom aluminum oxide resin. Directional transmission intensity measurements revealed frequency-dependent asymmetry in forward and backward wave propagation (in both experiments and simulations), consistent with passive acoustic isolator behavior. X-ray micro-CT imaging of AI-MM samples revealed dimensional deviations, apex rounding, and local density variation. Attenuation spectra showed that AI-MM backings consistently outperformed homogeneous controls in both simulation and experiment, with frequency-dependent trends indicating enhanced scattering and viscous losses. A local attenuation peak near 2.6 MHz was within the operational range estimated from the measured geometry (2.22-2.94 MHz), underscoring the importance of linking performance to real-world fabrication. These findings support the potential of AI-MMs as tunable passive components in ultrasound systems and highlight the need for integrated design, fabrication, and validation workflows.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145244520","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 center frequency of the PMUT is 4.89 MHz in air and 3.5 MHz in a gel-type couplant, along with a -6 dB photoacoustic (PA) bandwidth of 146%. A miniaturized PA sensing system (4.6 mm × 2.0 mm × 5.2 mm) was developed by integrating the PMUT with a compact vertical-cavity surface-emitting laser (VCSEL). Simulation results reveal critical parameters for optimizing a PA system. The increase in laser excitation energy correspondingly improves the efficiency of PA signal generation, and spatial non-uniformity in optical energy distribution requires algorithmic compensation to prevent signal distortion. The small footprint of the PMUT minimizes phase differences, enabling distortion-free signal detection at close range, while its broad bandwidth ensures high-fidelity signal capture at an optimized center frequency. Guided by these findings, the VCSEL parameters were optimized to a 28 ns pulse width and an average output power of 63.6 μW. Comprehensive characterization, including electrical impedance, acoustic response, and PA bandwidth tests, demonstrated the consistency of the PMUT fabrication process, broadband capability and superiority of the PMUT in close-range sensing. Phantom-based testing showed that the system can acquire multi-depth phantom signals, and the cylindrical wave radiation analysis further highlighted the critical role of laser-PMUT spacing in maintaining signal integrity. This feasibility study validates the compact system as a promising platform for portable PA devices under ideal phantom and ex vivo conditions.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145206374","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}

GVs establish a platform for biomolecular engineering and were successfully repurposed into acoustic reporter genes and acoustic biosensors. Alongside molecular engineering developments, a method called cross amplitude modulation (xAM) has emerged as the gold standard for non-destructive ultrasound imaging of GVs thanks to its sensitivity and specificity in living biological tissues. Here, we present latest xAM theory and imaging principles. Specifically, we report 1) analytical expressions for the X-wave beam width and primary-to-secondary lobes distance; 2) experimental observations of nondiffractive xAM beams; 3) a method to modulate the secondary lobe level of xAM beams; 4) a demonstration of the incoherent nature of the xAM image noise that can be leverage to increase sensitivity through frame averaging, 5) a beamforming formalism to enhance xAM contrast-to-noise ratio without reducing framerate. Ultimately, the rise of the field of Biomolecular Ultrasound will rest on the co-development of genetically encoded probes and dedicated imaging methods such as xAM and its 3D extension, nonlinear sound-sheet microscopy.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145137498","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 first method utilizes a longitudinal SAW (L-SAW) mode in X-cut LN to achieve a high phase velocity of 6500 m/s and a figure of merit (FoM) of 6.53 at 22.42 GHz, enabled by strong acoustic confinement and careful wavelength scaling.

The fabricated EG SH-SAW resonator achieves operation at 23.5 GHz with a coupling coefficient k2 of 1.6% and a FoM of 4.16.

The objective of this work was to quantify average deff(f) for needle hydrophones as a function of dg and f. Estimates of effective radii aeff(f) = deff(f) / 2 were inferred from directivity measurements from 0.5 to 20 MHz on 16 needle hydrophones with dg = 2ag ranging from 75 to 1000 μm (139 hydrophone / frequency combinations). Effective sensitive element diameter deff(f) exceeded dg by over 100 % when λ > 4dg (where λ is the wavelength). For kag > 0.75 (where k=2π/λ), deff(f) was consistent with the \"rigid piston\" (RP) theory, reinforcing a previous report from our laboratories. However, for kag < 0.75, deff(f) showed noticeable deviations from RP theory and fell between predictions from RP theory and predictions for an unbaffled (UB) circular piston. Examples: 1) For a needle hydrophone with dg = 75 μm at 1 MHz (kag = 0.16), the data imply that average deff = 505 μm. 2) For a needle hydrophone with dg = 400 μm at 500 kHz (common parameters for human transcranial neuromodulation; kag = 0.42), the data imply that average deff = 1215 μm.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145075093","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}

However, the presence of a container around a cavitating sample in experiments performed in vitro can introduce significant aberrations into recorded cavitation noise and resulting PAM images. These artefacts may lead to energy being incorrectly estimated or mapped to the wrong place, preventing accurate correlation between cavitation and bioeffects. In this work, we quantify these acoustic effects for six common types of sample container using an acoustic reciprocity experiment, then use the results to inform the design of a new container with improved acoustic transparency. Existing vessels were found to introduce up to 13 dB broadband insertion loss and change the location and spread of energy in PAM images by up to 1 mm and 25%, respectively. The new container caused up to 1.4 dB insertion loss (the lowest of any container tested) and introduced no significant phase aberration, source location error, or change in energy spread to the PAM images. Testing the new container with real cavitation noise produced very similar insertion loss figures of up to 1.6 dB. These results highlight deficiencies in existing sample containers for the purposes of quantifying cavitation activity with PAM, which is increasingly desired as cavitation matures as a therapy. The guidelines for acoustic transparency developed here may assist researchers in avoiding container aberrations and enable accurate measurement of cavitation energy in future studies.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"PP ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145075107","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}
