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).

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 artifacts 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 containers 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":"72 11","pages":"1476-1488"},"PeriodicalIF":3.7,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11164665","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":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In spinal cord injury research, small animal models are commonly used, but their size restricts the applicability of many standard ultrasound systems. Capacitive micromachined ultrasonic transducers (CMUTs) offer advantages over traditional piezoelectric transducers, including a smaller form factor, high design flexibility, and improved acoustic performance. CMUT structures made of polymers (polyCMUTs) can be produced cost-effectively and quickly, while potentially offering flexible, biocompatible transducers for next-generation ultrasound systems. This study introduces the first polyCMUT probe designed for imaging spinal cords in rats. A compact 11 MHz, 64 channel probe with a <inline-formula> <tex-math>$12.9times 6.5$ </tex-math></inline-formula> mm small tip was developed through a three-stage fabrication process, combining in-house manufactured polyCMUT arrays with electronics, integrated in a research imaging system. Performance evaluation included electrical impedance measurements, acoustic characterization, and in vitro and ex-vivo imaging. Quality analysis validated the stability of the fabrication process, demonstrating high yield and minimal variability, with a standard deviation in resonance frequency of less than 1%. The probe successfully visualized key anatomical structures like the central canal as well as real-time imaging of needle insertion into tissue. However, distinguishing between gray and white matter remained challenging due to limitations in frequency and bandwidth. This study demonstrates the potential of the polyCMUT technology for developing tailored ultrasound solutions. Future work will focus on optimizing high-frequency performance and advancing toward in vivo applications to provide meaningful tools in spinal cord injury research and therapeutic interventions.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"72 11","pages":"1437-1447"},"PeriodicalIF":3.7,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144952365","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}

SRUS represented by ultrasound localization microscopy (ULM) eliminates the point spread function (PSF) caused by diffraction by localizing sparse microbubbles in the image, and then constructs a super-resolution blood flow structure map through long-term image accumulation. It is worth mentioning that almost all current super-resolution strategies, including ULM, adopt postimage processing strategies. In optics, in addition to postimage processing super-resolution techniques, the design of the illumination light field is also a popular super-resolution imaging method. This inspired us to design the acoustic field to achieve a super-resolution blood flow imaging strategy based on structured acoustic field illumination. In this article, we propose a new structured acoustic field illumination design method, which achieves 2-D structured acoustic field design by improving the acoustic field calculation of Gerchberg–Saxton algorithm (GSA) based on Talbot effect. At the same time, we have designed a corresponding structured acoustic field reconstruction strategy that can adaptively reconstruct any structured illumination method, and the reconstructed image frame rate is comparable to that of multiangle plane wave. Combined with image postprocessing methods, we have obtained contrast-enhanced structured illumination ultrasound (CE-SIU), which reduces the full width at half maximum (FWHM) of the microbubble PSF, breaking through the lateral resolution limit of contrast-enhanced imaging. The super-resolution strategy based on acoustic field design proposed in this study provides new insights and perspectives for the development of the overall technical route of SRUS.","PeriodicalId":13322,"journal":{"name":"IEEE transactions on ultrasonics, ferroelectrics, and frequency control","volume":"72 10","pages":"1401-1413"},"PeriodicalIF":3.7,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144952304","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}

This ultrawide bandwidth facilitates accurate pulse-echo signal reception across a broad frequency range while minimizing signal overlap caused by ringdown effects. Moreover, optimizing the PMUT array size relative to wavelength achieved a highly directional 5° acoustic beam, ensuring effective penetration through high attenuation or multilayered structures.
