摘要： A multiphase flow meter (MPFM) for determining component flowrates of multiple component phases within a multiphase mixture having a multiphase flowrate is disclosed. The MPFM may include a first venturi having a first constriction diameter; a second venturi having a second constriction diameter; a gamma ray tomograph fluidly connected to the first venturi and the second venturi; and a tomography controller communicably connected to the gamma ray tomograph. The tomography controller may be configured to calculate a first venturi multiphase flowrate using a first pressure change sensed across the first venturi and a second venturi multiphase flowrate using a second pressure change sensed across the second venturi. Additionally, the tomography controller may be configured to determine the component flowrates of the multiple component phases using a multiphase flowrate calculated from the first venturi multiphase flowrate and the second venturi multiphase flowrate.

摘要： An X-ray detector module includes a plurality of evaluation circuits, coupled to at least one converter circuit, each evaluation circuit including a multiplicity of pixel electronics circuits for processing the electrical signals from the converter circuit pixel by pixel; and a number of forwarding circuits, a forwarding circuit including at least a first data input for receiving a measured data set from a first evaluation circuit and at least a second data input for receiving a measured data set from a second evaluation circuit, or for receiving at least one forwarded measured data set from a further forwarding circuit of the number of forwarding circuits. Each forwarding circuit is constructed to forward the measured data sets that are received by way of the first data input and second data input to a coupled receiving circuit over a common data output.

摘要： A method is for correcting an imbalance in a computed tomography system, in which a supporting structure includes a radiation source is fitted on a fixed mounting frame. The supporting structure rotates together with the radiation source about a measurement space, in which is fixed in place a measurement object having a known attenuation response for the radiation emitted by the radiation source. The method includes detecting first measurement data of the radiation while the supporting structure rotates about the measurement object, determining an imbalance arising during the rotation of the supporting structure on the basis of the acquired first measurement data of the radiation, and determining a position and a weight of at least one counterweight on the supporting structure in order to reduce the determined imbalance, or determining correction data, which is used to correct the imbalance in software.

摘要： There is provided an X-ray Talbot capturing apparatus that emits X-rays in a cone beam shape from an X-ray generator, capable of producing gratings as easily as possible and of minimizing a production cost. An X-ray Talbot capturing apparatus 1 includes a G1 grating that is a phase grating, a G2 grating that is an absorption grating, a X-ray generator 11 that emits the X-rays, and an X-ray detector that includes a plurality of two-dimensionally arrayed conversion elements and captures a moire image Mo formed on the G2 grating. The G2 grating is located at a position where a self-image of the G1 grating 14 is formed, and both of the G1 grating and the G2 grating are in a plane shape. Slits of the G1 grating are formed to be perpendicular to a surface direction of a substrate on which the grating is formed, whereas slits of the G2 grating are formed to be parallel with the X-rays emitted in the cone beam shape from a focus F of the X-ray generator.

摘要： A x-ray micro tomography system provides the ability to proscriptively determine regularization parameters for iterative reconstruction of a sample, from projection data of the sample. This allows a less experienced operator to determine the regularization parameters with adequate precision.
