  • A wireless chemical sensing scheme using ultrasonic imaging of microbubble embeded hydrogel

    In this paper, we demonstrate a wireless chemical sensing scheme using ultrasonic imaging of a microbubble-functionalized hydrogel, which we call “bubblegel.” By incorporating oxygen microbubbles into a hydrogel, its volume transition, which is responsive to its chemical microenvironment, can be wirelessly monitored by ultrasonic imaging; measuring volume directly or measuring the reflected acoustic intensity from the surface of the bubblegel. Here a bubblegel fabricated with pH-sensitive poly (methacrylic acid-co- acrylamide) hydrogel is investigated in vitro. The sensor shows a sensitivity of 19.49 gray-scale intensity/pH and a resolution of 0.25 pH unit in the linear response region (between pH 4 and 6). It is expected that the concept can be adapted to hydrogels sensitive to other stimuli (e.g., glucose, biomarkers, etc.).

  • Study on Ultrasonic Imaging Testing Technique of Angle Probe for Girth Weld of Hydraulic Cylinder Used in Coal Mine

    Taking girth weld of hydraulic cylinder used in coal mine as object, the principle of ultrasonic testing and method of ultrasonic scan imaging for angle probe are studied, the definitions of ultrasonic scan image for angle probe are given, and the corresponding relationship between scan image and artificial defect in the sample is analyzed in this paper. Then, the mathematical models of ultrasonic B-scan and C-scan imaging for artificial defect are established. Moreover, the experimental verification is carried out by using the ultrasonic imaging testing system. The results show that ultrasonic scan images are identical with description of mathematical models. And these lay a good foundation for locating, quantitative, and qualitative analysis of flaws.

  • Multi-aperture focus ultrasonic imaging technique based on virtual source

    In this paper, a multi-aperture synthetic focusing technique based on virtual source is studied, which improves the lateral resolution and depth of the ultrasonic imaging with respect to the single array dynamic synthetic aperture focusing technique (SAFT). It only needs to store the N numbers data for the A scan line, and the complexity of the algorithm is greatly reduced compared with the full focus technology (TFM) with the maintenance of image quality. Using Field II simulation and Multi2000 device experiment results show that compared with the single element dynamic synthetic aperture technology, virtual source multi-aperture synthetic focusing ultrasonic technique (VS- MSAFT) effectively improves the lateral resolution and depth of permeation, furthermore to improve the quality of ultrasound imaging.

  • Ultrasonic imaging research platform with GPU-based software focusing

    We have designed and implemented an ultrasonic imaging research platform that performs all signal processing, including beamforming and image processing, using software on a GPU. An operating software is developed on a PC that can control RF data acquisition hardware to accommodate ultrasound images of various formats. Beamforming methods that include conventional scan line based imaging, scan line-based two-way dynamic focusing imaging, plane wave imaging, synthetic plane wave imaging, defocused transmission imaging, multi-beam scan line imaging, and color Doppler imaging are implemented by CUDA which runs on a GPU. Depending on the transmit and receive mode, a variety of experimental data acquisition conditions and various filter parameters can be changed in real time by a graphical user interface, and the RF data can be stored in a hard disk without a limit on the number of frames. Since the software for operation and signal processing can be flexibly changed, the developed system is a very useful research platform for ultrasound image acquisitions. We have used a GeForce GTX 980 (NVIDIA) desktop graphics card with a clock frequency of 1.126 GHz and 4 GB memory and a PC with an Intel Core i7-5820K 3.3-GHz CPU and a system memory of 16 GB under 64-bit Windows 7 along with an analog front-end capable of transmitting 128 channels and receiving 64 channels, obtaining images using a 5-MHz, 128-channel linear array probe.

  • Image Speckle Reduction and Coherence Enhancement in Underwater Ultrasonic Imaging Based on Wavelet Transform

    In order to reduce the underwater ultrasonic image speckles and to enhance the image characteristics, an anisotropic diffusion model is established based on the wavelet transform in this paper. At the same time, it also provides the steps of the algorithmic architecture and analyzes the key links of the model during its application. Two-check experiments have been done using simulation data and real underwater ultrasonic image respectively. In experiment a compare research for underwater ultrasonic image has been done using the method and other traditional methods. After performing the WLAD-model-based image speckle reduction and coherence enhancement to the underwater ultrasonic image, we find that this algorithm has the ability to remove the image speckles and enhance the edges. This algorithm can well be applied to removing the speckles and enhancing the edges in the underwater ultrasonic image.

  • A high frequency ultrasonic imaging of welded joints

    The paper presents chosen results obtained during the investigation of welded joints (laser, spot and friction) tested using acoustic microscopy method. Detection of welds properties and the defects strongly depends on ultrasonic transducer's parameters. For the purpose of this research a prototype hardware setup was built - enabling evaluation of various types of ultrasonic probes. The system can be easily adjusted to the geometry of an object and is well equipped with appropriate software for the analysis and processing of images such as B-scan or C-scan. The setup enables determination of welds geometry, in particular the depth of the weld penetration in some cases.

  • MVDR based adaptive beamformer design and its FPGA implementation for ultrasonic imaging

    Adaptive beamforming outperforms its non-adaptive counterpart in that it is capable of achieving a narrower main lobe and suppressing interference. It, however, calls for intensive computations to obtain the weighting factors. In this paper, we present an MVDR (minimum variance directionless response) based adaptive beamformer design for ultrasound imaging and implement the design in an FPGA platform. An efficient matrix inversion computing scheme, which can reduce the complexity by an order, is first developed to facilitate real time operations. Simulation results indicate the performance degradation due to this simplification measure is negligible. A linear systolic array design is further devised to support highly concurrent and pipelined computations. Finally, the design is implemented in a Xilinx Vertex XC7z045ffg900-2 FPGA platform. The working frequency can reach 98 MHz, and the MVDR coefficients can be updated every 64 clock cycles. For the entire ultrasound system, the proposed design can support a 64 lines by 512 pixels scanning at a frame rate of 20fps.

  • Acoustic computer model for ultrasonic imaging of heavy liquid metal nuclear reactor

    Liquid metal coolants are being considered in several designs of Gen IV nuclear power plants. To enable safe operation, methods of the reactor vessel interior imaging must be set up. In this paper we consider the development of the ultrasonic technique allowing visualisation in liquid Pb/Bi (lead-bismuth eutectic) alloy. We propose a computer model which makes possible computation of signals reflected by submerged in liquid Pb/Bi stainless steel components with a complicated geometry and arbitrary orientation in space. Approximation of the inspected objects with planar triangular elements was used. The simulations show that with this model objects of complicated shapes can be identified and their parameters estimated.
