Abstract: The present disclosure provides a system and method for real-time visualization of a material during ultrasonic non-destructive testing. The system includes a graphical user interface (GUI) capable of showing a three-dimensional (3-D) image of a composite laminate constructed of a series of two-dimensional (2-D) cross sections. The GUI is capable of displaying the 3-D image as each additional 2-D cross section is scanned by an ultrasonic testing apparatus in real time or near real time, including probable defect regions that contain a flaw such as a hole, crack, wrinkle, or foreign object within the composite. Furthermore, in one embodiment, the system includes an artificial intelligence capable of highlighting defect areas within the 3-D image in real time or near real time and providing data regarding each defect area, such as the depth, size, and/or type of each defect.

Abstract: While 3D ultrasound imaging is becoming a powerful tool in medical field. the main drawback is the difficulty to image large 3D volume. mainly related to the dimensions of the 2D array of transducers. In order to not lose in spatial resolution, it is necessary to use an array of transducers. wherein the size of the transducers does not exceed the wavelength of the ultrasound wave. Such requirement leads to dimensions of array for imaging large 3D volume which are not reachable or at too high cost with the current technology. The present disclosure overcomes the above technology limitation by using greater transducers, and where each transducer has a reception surface with a curved shape or is fitted with an acoustic lens. Such configuration of transducers leads to 2D array of transducers suitable for imaging large 3D volume, as a brain or a heart. with high resolution and high sensitivity.

Abstract: Ping-based imaging systems may be used for tracking motion of hard or soft objects within an imaged medium. Motion detection and motion tracking may be performed by defining fingerprint points and tracking the position of each fingerprint point based on the echoes of multiple transmitted pings.

Abstract: An ultrasonic diagnostic imaging system produces 3D images by scanning a target volume with a mechanical probe, which scans the target volume by sweeping the scan plane of an array transducer through the target volume in an elevation direction. The array transducer has two selectable focal depths, and a plurality of scan planes of image data are acquired with a far field focus, and a plurality of scan planes of image data are acquired with a near field focus. The scan planes acquired with the far field focus are separated in the elevation direction by a distance which satisfies a spatial sampling criterion in the far field, and the scan planes acquired with the near field focus are separated in the elevation direction by a distance which satisfies the spatial sampling criterion in the near field, resulting in fewer scan plane acquisitions with the near field focus that the number of scan plane acquisitions with far field focus and hence an improved volume rate of display.

Abstract: Estimation and imaging of linear and nonlinear propagation and scattering parameters in a material object where the material parameters for wave propagation and scattering has a nonlinear dependence on the wave field amplitude. The methods transmit at least two pulse complexes composed of co-propagating high frequency (HF) and low frequency (LF) pulses along at least one LF and HF transmit beam axis, where said HF pulse propagates close to the crest or trough of the LF pulse along at least one HF transmit beam, and where one of the amplitude and polarity of the LF pulse varies between at least two transmitted pulse complexes. At least one HF receive beam crosses the HF transmit beam at an angle, to provide at least two HF cross-beam receive signals from at least two transmitted pulse complexes with different LF pulses.

Abstract: A system and method for capturing ultrasound signals from a hemispheric imaging region (e.g., by a stationary array of transducer elements arranged in the shape of a faceted hemisphere) and estimating scattering measurements that would be made by a virtual array in the opposite hemisphere (e.g., by a network of processors that receive and process the transmitted ultrasound signals in parallel) by forming an initial estimate of a medium variation for each of a plurality of subvolumes in the scattering object to form an estimated object, calculating residual scattering by using a difference between a scattering response calculated for the estimated object and measured ultrasound signals received from the scattering object, forming an initial three-dimensional image of the scattering object, and extrapolating a difference between the scattering response calculated for the estimated object and the measured ultrasound signals received from the scattering object.

Abstract: A three-dimensional (3D) terrain reconstruction method for a scoured area around bridge pier foundation based on a mechanical scanned imaging sonar includes scanning an overall terrain of a scoured area around bridge pier foundation with a sonar from different azimuths to acquire n sonar images of a foundation scouring terrain; intercepting multiple analysis sections from each of acquired sonar images at a same distance; extracting key parameters of upper and lower edges on a terrain imaging strip in each of the analysis sections in the image, and transforming extracted parameters to a 3D space, a fan-shaped beam surface of the sonar being represented with a fan-shaped arc; recognizing a scour terrain profile in the analysis section; recognizing terrain profiles one by one, and respectively extracting spatially scattered 3D coordinate data; and performing interpolation and fitting on the spatially scattered data, thus implementing 3D reconstruction for the foundation scouring terrain.
