There are provided methods and systems for assessing the health of an asset. For example, a system is provided. The system may include a processor and a memory including instructions that, when executed by the processor, cause the processor to perform operations consistent with identifying a defect in a component of an asset. The operations may include fetching from an inspection system, a plurality of images acquired from an inspection of the component of the asset by the inspection system. The operations may include identifying, based on an image processing technique codified and included as part of the instructions, a subset of images from the plurality of images. The subset of images is representative of the defect in the component of the asset, and the image processing technique is selected from the group consisting of an auto-distress ranking technique, a structural similarity technique, a mean-subtracted filtering technique, and a Hessian norm computation technique.

An ultrasonic sensor assembly for testing a pipe includes a first and second transducer rings attached to the pipe and spaced apart along a length of the pipe. The first transducer ring includes a plurality of transmitters for transmitting a wave, such as a non-dispersive guided wave. The first transducer ring transmits the wave along the pipe. The second transducer ring includes a plurality of receivers for receiving the wave. A relative position of the first transducer ring with respect to a circumferential position of the second transducer ring is determined based on characteristics of the wave received by the second transducer ring. A method of positioning the ultrasonic sensor assembly on the pipe is also provided.

An imaging technique is provided for acquiring scatter free images of an object. The technique includes acquiring a plurality of projection images of the object using a source and a detector oriented at a plurality of projection angles relative to the object, and generating a plurality of scatter free projection images by correcting the plurality of projection images based on respective ones of a plurality of stored scatter images. The scatter images are generated and stored for each of the projection angles by positioning a scatter rejection plate between the object and the detector. The technique further includes reconstructing a three-dimensional image of the object based on the scatter free projection images.

Imaging system and method with scatter correction

A method of providing an image of an interior of a structure containing regions having different conductivities or admittivities. In one embodiment a series of electrical signal sets is applied to a series of electrodes, each signal set generating a rotating electric field. A measured set of electrical signals obtained from the electrodes are used to calculate a conductivity or admittivity distribution representative of the interior of the structure in a region about which the electrodes are positioned. The process of calculating the distribution includes defining a cost function, e.g., the energy function based on the distribution, and a forward model expressing the measured set of electrical signals as a function of the change in voltage values with respect to conductivity or admittivity and requiring that the partial derivative of the difference between the energy function and a function based on the forward model equal zero.

A system and method for performing a continuity test on a lightning conduction system of a wind turbine are disclosed. The system generally includes a testing device having a blade ring configured to be positioned around at least a portion of an outer perimeter of a rotor blade of the wind turbine. A carriage may be attached to the testing device and a cable may be attached to the carriage. The cable may generally extend between a first anchor point and a second anchor point, wherein the anchor points are spaced apart from one another such that a lightning receptor of the lightning conduction system is disposed between the anchor points. Additionally, the cable may be coupled between the anchor points such that, as the cable is displaced, the testing device is moved to a position at which an electrically conductive member of the testing device contacts the lightning receptor.

An X-ray tube anode assembly and an X-ray tube assembly are disclosed that include an X-ray target and a drive assembly configured to provide an oscillatory motion to the X-ray target. The drive assembly is configured to provide an oscillatory motion to the target assembly.

High flux X-ray target and assembly

An X-ray tube anode assembly, an X-ray tube assembly and a method for heat management to an X-ray assembly having a movable X-ray target having a target surface. The anode assembly includes a drive member arranged and disposed to provide oscillatory motion to the target assembly and a target surface that is configured to remain at a substantially fixed distance from a cathode assembly during oscillatory motion.

A system is provided for radiographic inspection of an object comprising multiple having different material properties. The system comprises a radiation source configured to generate radiation, a display unit for generating a graphical user interface (GUI) including multiple fields. A user enters input data via the fields in the GUI. The input data relates to one or more material properties for each of the regions. A processor is configured to compute a plurality of exposure parameters based on the input data.

Radiographic inspection system and method

A digital radiography imaging system for acquiring digital images of an object, and a method for transforming digital images into an absolute thickness map characterizing the object under inspection. The system includes a radiation source for directing radiation through a desired region of the object, and a radiation detector having a plurality of sensing elements for detecting radiation passing through the object. Numerical data generated from each sensing element is calibrated, for example by correcting for variations in radiation paths between the source and detector, by correcting for variations in the spatial frequency response (MTF) of the detector, by correcting for variations in the geometric profile of the object under inspection, and by correcting for material contained in and/or around the object. The calibrated data is processed in order to generate and display an absolute thickness map of the object. The calibration procedures are adapted for extracting a thickness map from both isotope sources and X-ray tube sources.
