    摘要: An inspection device includes a ray source that irradiates an object to be inspected with energy rays, a detection unit that detects energy rays that have passed through the object to be inspected, a displacement mechanism that sets a relative position of the object to be inspected and the ray source by displacing at least one of the object to be inspected and the ray source in relation to the other, an internal image generation unit that generates an internal image of the object to be inspected based on a detection amount distribution of the energy rays detected by the detection unit, and a control unit that controls the displacement mechanism based on the detection amount distribution of the energy rays detected by the detection unit.

    摘要: A computer-tomography (CT) imaging system, comprising an imaging data acquisition system. The imaging data acquisition system includes a plurality of sets of a detector section, a storage section, and an aggregation section. The detector section includes a plurality of detector elements each being configured to convert radiation into electric signals. The aggregation section is configured to aggregate imaging data carried by the electronic signals from the detector section. The storage section is connected with an output of the detector section and an input of the aggregation section. The storage section comprises a predetermined number of non-volatile memories to store the imaging data from the corresponding detector elements.

    摘要: A method for determining porosity of a part is provided. The method includes: determining scan data of the part, the scan data including data of a plurality of sequential segments; determining a background model for the part, the scan data, or both; and determining a bulk porosity based on a difference between the scan data and the background model.

    摘要: A system for computed tomography inspection can include a stage, a stationary radiation source, a stationary radiation detector, and a controller. The stage can secure a target thereon and rotate about a rotation axis. The radiation source can emit a beam of penetrating radiation from a focal point that is directed upon a portion of the target. The radiation detector can include a sensing face configured to acquire measurements of radiation beam intensity incident thereon as a function of position. The controller can command the stage to translate from a first position to a second position in a direction transverse to a central axis of the radiation beam. A magnification of the target at the first and second positions can be approximately equal. The stage does not translate transverse to the central axis of the radiation beam during measurement of the radiation beam intensity by the detector.

    摘要: The present disclosure may provide a detector module of an imaging apparatus. The detector module may include a detector assembly configured to detect a signal associated with an object; a cover assembly configured to accommodate the detector assembly; and at least one cooling assembly operably coupled to the cover assembly. The at least one cooling assembly may be configured to cool the detector assembly by providing a cooling medium to the cover assembly.

    摘要: Overlapping pores in a multiscale model of heterogeneous core formation contributes errors during flow simulations. A scale-coupled multiscale modeling that corrects for contributions of overlapping pores may be used to determine capillary pressure and relative permeability of the heterogenous core formation more accurately. The effects of overlapping pores may be removed by converting pores that have a certain radius or are filled with certain fluids into solid regions. The effects of overlapping pores may also be removed by running flow simulations on a modified model and correcting various fluid properties of the core formation with the results.

    摘要: There is provided an acquiring method of a projection image of a sample whose shape is uneven with respect to a rotation center, the method comprising the steps of setting the sample S0 at a position of the rotation center C0 provided between an X-ray source 116a and a detector 117, and acquiring the projection image of the sample S0 at each different rotation angle for each different magnification ratio over a rotation angle of 180° or more by rotating the sample S0 around the rotation center C0, and by relatively changing a separation distance between the X-ray source and the rotation center, or a separation distance between the rotation center and the detector in an optical axis direction according to the shape of the sample S0 and the rotation angle of the sample S0.
