The phantom includes a container, a boundary formed within the container, and a curved scanning surface. The container includes a top surface, a bottom surface opposite the top surface, and a wall mounted between the top surface and the bottom surface to form the container. The boundary is configured to hold a tissue mimicking material. The curved scanning surface is formed in the top surface in a direction towards an interior of the container. The curved scanning surface is shaped to support translation perpendicular to an image plane of an application end of an ultrasound transducer along at least a portion of an axis extending between a first location on the curved scanning surface and a second location on the curved scanning surface.

摘要： A device and a method for detecting at least one defect in a test object (2). At least one test head (1) radiates an ultrasonic signal at different measuring points (MP) into the test object (2) with each point at an insonation or radiation angle (α) in order to ascertain multiple measurement data sets (MDS). The angle is constant for each data set (MDS). An analyzing unit (4) carries out an SAFT (Synthetic Aperture Focusing Technique) analysis for each ascertained measurement data set (MDS) using a common reconstruction grid (RG) inside the test object (2) in order to calculate an SAFT analysis result for each measurement data set (MDS). The analyzing unit (4) superimposes the calculated SAFT analysis results in order to calculate an orientation-independent defect display value (SRP) for each reconstruction point (RP) of the common reconstruction grid (RG).

The device comprises an ultrasonic emitter and an ultrasonic receiver, both of which are set on the side opposite to the processing area, and it further comprises an ultrasonic analyzer connected to the ultrasonic receiver. The ultrasonic emitter emits ultrasonic waves for testing to the substrate, the ultrasonic receiver receives the ultrasonic waves reflected from the substrate, and the ultrasonic analyzer connected to the ultrasonic receive analyzes the received ultrasonic waves to determine whether the substrate has been broken. In the present invention, the fragment on anywhere comprising the processing area and the non-processing area of the substrate can be detected, the broken substrate can be picked out overall, and thus preventing the broken substrate from damaging the production line and the products.

摘要： An ultrasonic measuring system includes an ultrasonic probe and a sheet member. The ultrasonic probe has an ultrasonic sensor section and a probe side engaging section. Ultrasonic waves emitted from the ultrasonic sensor section are transmitted through the sheet member to a target sample. The sheet member has a sheet side engaging section. The probe side engaging section slidably engages with the sheet side engaging section so that the ultrasonic probe slides along the sheet member while the ultrasonic sensor section faces a sheet surface of the sheet member.

摘要： A computer aided method is provided for coupling non-destructive inspection data for a material or structure to an analysis tool. The method includes receiving a voxel data representation of a damaged area of the material or structure, and generating a finite element mesh based on the voxel data representation. The finite element mesh includes a plurality of nodes, each node corresponding to one or more voxels of the voxel data representation. The method further includes integrating damage information from the voxel data representation into the finite element mesh by applying at least one integration rule, the damage information indicating whether or not a given voxel has sustained damage. Damage information for areas of the finite element mesh that do not include damage information is interpolated by applying at least one interpolation rule. A finite element model including a finite element mesh having damage information associated therewith is output.

摘要： A self-contained, holonomic motion tracking solution for supplementing the acquisition of inspection information on the surface of a structure, thereby enabling the real-time production of two-dimensional images from hand-held and automated scanning by holonomic-motion of non-destructive inspection (NDI) sensor units (e.g., NDI probes). The systems and methods disclosed enable precise tracking of the position and orientation of a holonomic-motion NDI sensor unit (hand-held or automated) and conversion of the acquired tracking data into encoder pulse signals for processing by a NDI scanning system.
