摘要： This disclosure describes systems and methods for ultrasound imaging and targeting. In one example, the systems and methods improve targeting and imaging through a heterogenous medium by using the angular spectrum approach (ASA) alone or in combination with passive acoustic mapping (PAM). In another example, the systems and methods improve the ultrasound imaging of vessels using microbubbles. The imaging of the vessels is also aided by the ASA and PAM. A closed loop controller is described that adjusts the ultrasound pressure provided to a region of interest to a desired pressure based at least in part on the harmonic, ultra-harmonic, sub-harmonic, or broadband frequency ranges for the microbubbles.

摘要： A coupler and a chuck are described. The chuck is configured to secure an article while the wafer is undergoing an inspection process. The chuck has a plurality of vacuum areas. Some vacuum areas hold the wafer in place while other vacuum areas suction couplant from the edge surface of the wafer. The coupler is used to inspect a surface and subsurface of the wafer for defects and includes a sensing device, which may be a transducer. One or more couplant inlet couplings are disposed on a second portion of the coupler, the couplant inlet couplings provide a couplant to a portion of the wafer inspected by the sensing device. A plurality of vacuum inlet couplings is disposed on a third portion of the coupler. At least one of the vacuum inlet couplings provide suction through a recessed portion of a lower surface of the coupler to remove couplant that is outside the portion of the wafer that is being inspected by the sensing device.

摘要： An object information obtaining apparatus includes an irradiation unit configured to irradiate the object with measurement light, a probe configured to receive an acoustic wave propagating from the object, a driving unit configured to move the irradiation unit so that a relative position of the irradiation unit with respect to the object is changed, an image capturing unit configured to capture an image of the object and a control unit. The control unit is configured to control a display unit in such a manner that an irradiation position of the measurement light is displayed on the image captured by the image capturing unit.

摘要： Described here are systems and methods for phase velocity imaging using an imaging system, such as an ultrasound system, an optical imaging system (e.g., an optical coherence tomography system), or a magnetic resonance imaging system. In general, systems and methods for constructing phase velocity images (e.g., 2D images, 3D images) from propagating mechanical wave motion data are described. The systems and methods described in the present disclosure operate in the frequency domain and can be implemented using a single frequency or a band of selected frequencies. If there are multiple mechanical wave sources within the field-of-view, directional filtering may be performed to separate mechanical waves propagating in different directions. The reconstructions described below can be performed for each of these directionally filtered components.

摘要： A method includes receiving data characterizing a first acoustic signal reflected by a first defect in a target object, and a first depth of the first defect relative to a surface of the target object. The first acoustic signal is detected by a detector located at a first location on the surface of the target object. The method also includes assigning a defect color to the received data based on an amplitude value associated with the first acoustic signal and one or more of a first predetermined threshold value and a second predetermined threshold value associated with the first depth. The method further includes rendering, in a graphical user interface display space, a first visual representation of the first acoustic signal in a graph including a first axis indicative of target object defect depth and a second axis indicative of amplitudes of acoustic signals detected by the detector. The first visual representation of the first acoustic signal includes the assigned defect color.

摘要： 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.

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 system and method for using a microscope to aurally observe a specimen in a fluid is provided. In one embodiment of the present invention, the microscope is modified to include a first beam splitter, splitting a visual of the specimen magnified by the objective lens. A first beam is then provided to an audio frequency modulation sensing (AFMS) device, whose function is to sense photoacoustic modulation of the specimen and to extract aural data, allowing sound energy to be observed by a user (e.g., displayed on screen, played on a speaker, etc.). The second beam is provided to a second beam splitter, allowing visuals to be provided to the eyepiece and to at least one other sensor, where a second visual of the specimen is captured. The second visual can then be displayed on a screen in time synchronization with aural data provided by the AFMS device.
