摘要： A scanning device is provided. The scanning device includes a frame having a first portion and a second portion pivotably coupled to the first frame portion. The scanning device also includes a couplant source disposed in the first frame portion along with a couplant assembly. The couplant assembly includes a first couplant line disposed completely within the first frame portion and the second frame portion. The couplant assembly also includes a second couplant line extending from the first couplant line and out of the second frame portion at a first end of the second couplant line. The couplant assembly has a couplant line branch extending from the second couplant line where a sensor assembly of the ultrasound scanning device couples with the couplant line branch at an end opposite the second end of the second couplant line.

摘要： Transmit-Receive Longitudinal (TRL) probes can be used for the inspection of noisy material, such as austenitic materials. By using various techniques, an inspection area is not constrained by a wedge design of an ultrasonic probe and the benefits of using a linear probe array (rather than a matrix) are maintained. Volumetric or TFM-like imaging on austenitic materials using a linear transmit array and a linear receive array that are out of plane with one another (a TRL configuration) and not in the main imaging place can simplify the inspection and analysis of such materials. For each scan position, an ultrasound probe can acquire acoustic imaging data. Then, a processor can then combine acquisitions from adjacent scan positions to create an imaging result using synthetic aperture focusing technique (SAFT) principles to recreate a focalization in a passive axis of the probe.

摘要： Systems and methods are disclosed for conducting an ultrasonic-based inspection. The systems and methods perform operations comprising: receiving a plurality of scan plan parameters associated with generating an image of at least one flaw within a specimen based on acoustic echo data obtained using full matrix capture (FMC); applying the plurality of scan plan parameters to an acoustic model, the acoustic model configured to determine a two-way pressure response of a plurality of inspection modes based on specular reflection and diffraction phenomena; generating, by the acoustic model based on the plurality of scan plan parameters, an acoustic region of influence (AROI) comprising an acoustic amplitude sensitivity map for a first inspection mode amongst the plurality of inspection modes; and generating, for display, a first image comprising the AROI associated with the first inspection mode for capturing or inspecting the image of the at least one flaw.

摘要： An acoustic inspection system can be used to generate a surface profile of a component under inspection, and then can be used to perform the inspection on the component. The acoustic inspection system can obtain acoustic imaging data, e.g., FMC data, of the component. Then, the acoustic inspection system can apply a previously trained machine learning model to an encoded acoustic image, such as a TFM image, to generate a representation of the profile of one or more surfaces of the component. In this manner, no additional equipment is needed, which is more convenient and efficient than implementations that utilize additional components that are external to the acoustic inspection system.

摘要： A material profile can be determined by assuming an elliptical or circular arc geometry and by using acoustic noise generated by diffuse internal reflection and/or specular reflection on the internal (ID) or external (OD) interface of the material under inspection, such as a pipe or curved plate. A non-destructive testing (NDT) technique can acquire acoustic data of the material using an ultrasonic signal. The acquired acoustic data can be filtered such that the acoustic noise generated by diffuse internal reflection and/or specular reflection is separated from any flaws in the material. Positions of the acoustic noise can be determined and then a regression technique can be applied to the positions, which can generate an equation of a circle, for example, such as to provide a radius and thickness of the pipe or curved plate.

摘要： Examples described herein include adding a digital watermark into acoustic data. For example, the digital watermark data can be embedded using a key such that the watermark data is spread across a spectrum of the acoustic data. Thus, the data for the digital watermark may have no or minimal visible impact in the images generated using the marked acoustic data. The digital watermark may provide improved security and privacy. Moreover, the digital watermark may be incorporated into the reconstruction process of images.

摘要： Systems and methods are disclosed for conducting an ultrasonic-based inspection. The systems and methods perform operations comprising: receiving, by one or more processors, data indicative of a detected tag on a specimen, the tag associated with one or more ultrasonic-based inspections that were previously performed on the specimen; retrieving, by the one or more processors, based on the detected tag, configuration data for a non-destructive testing (NDT) instrument, the configuration data being associated with the one or more ultrasonic-based inspections that were previously performed on the specimen; generating, by the one or more processors, new configuration data for the NDT instrument to perform a new inspection of the specimen at least in part using the received configuration data; and performing the new inspection of the specimen based on spatially positioning the NDT instrument relative to a position of the tag on the specimen.

摘要： A compression technique can be used for processing or storage of acquired acoustic inspection data. For example, data indicative of peak values of an A-scan time-series can be stored to provide a compressed representation of such time-series data. A representation of the original A-scan data can be reconstructed, such as using the data indicative of the peak values, and a digital filter. Such an approach can dramatically reduce a volume of data associated an acoustic acquisition, such as a Full Matrix Capture (FMC) acquisition to be used for Total Focusing Method (TFM) beamforming and related imaging.

摘要： An acoustic technique can be used for performing non-destructive testing. For example, a method for acoustic evaluation of a target can include generating respective acoustic transmission events via selected transmitting ones of a plurality of electroacoustic transducers, and in response to the respective acoustic transmission events, receiving respective acoustic echo signals using other receiving ones of the plurality of electroacoustic transducers, and coherently summing representations of the respective received acoustic echo signals to generate a pixel or voxel value corresponding to a specified spatial location of the target. Such summation can include weighting contributions from the respective representations to suppress contributions from acoustic propagation paths outside a specified angular range with respect to a surface on or within the target, such as to provide an acoustic path-filtered total focusing method (PF-TFM).

摘要： An ultrasound probe can detect flaws in an object in a non-destructive manner. The probe includes a row-column addressed (RCA) array with a plurality of row and column electrodes. The row and column electrodes are configurable to have at least four states: 1) a transmission state, 2) a reception state, 3) a ground state, and 4) a high impedance state. The probe also includes a control circuit to operate the RCA array in different transmission and reception configurations.
