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":"72 4","pages":"530-538"},"PeriodicalIF":3.0,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10915700","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":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the large-scale data collection and annotation, particularly in medical fields, is often costly and time consuming, especially when healthcare professionals are already burdened with their clinical responsibilities. Ensuring that a model remains robust across different imaging conditions—such as variations in ultrasound devices and manual transducer operation—is crucial in the ultrasound image analysis. The data augmentation is a widely used solution, as it increases both the size and diversity of datasets, thereby enhancing the generalization performance of DNNs. With the advent of generative networks such as generative adversarial networks (GANs) and diffusion-based models, the synthetic data generation has emerged as a promising augmentation technique. However, comprehensive studies comparing classic and generative method-based augmentation methods are lacking, particularly in ultrasound-based breast cancer imaging, where variability in breast density, tumor morphology, and operator skill poses significant challenges. This study aims to compare the effectiveness of classic and generative network-based data augmentation techniques in improving the performance and robustness of breast ultrasound image classification models. Specifically, we seek to determine whether the computational intensity of generative networks is justified in data augmentation. This analysis will provide valuable insights into the role and benefits of each technique in enhancing the diagnostic accuracy of DNN for breast cancer diagnosis.

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 3-D 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 2-D complex-valued convolutional neural network (CCNN) (CL-UNet) as the teacher model, utilizing I/Q signal input. Subsequently, a 2-D real-valued convolutional neural network (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":"72 4","pages":"440-453"},"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}

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 projection (FP) 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 sidelobes and hot spots.

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.
