A distance SRD can be obtained from sizes of projection images of a calibration instrument on a table at a first point (that is an imaging position) and a second point and a distance between rotation center axes of the table at the first point and the second point. Furthermore, a distance SDD can be obtained by adding up the distance SRD thus obtained and a distance between an X-ray detector and the rotation center axis of the table at the first point, and a ratio between the distances SRD, SDD is taken as an imaging magnification of imaging at the first point.

A radiation detection device includes: a radiation detection panel; a supporting member that supports the radiation detection panel at a side of a first surface of the supporting member; and a housing that accommodates the radiation detection panel and the supporting member, and the supporting member has one or more concave portions at the first surface.

A non-destructive inspection method for inspecting an object to be inspected using a plurality of different types of non-destructive inspection means is shown. The method includes the following, fixedly forming common marks that can be detected by any of the plurality of non-destructive inspection means on the object to be inspected; then detecting the object to be inspected including the marks by the plurality of non-destructive inspection means respectively; and comparing the detection results by the plurality of non-destructive inspection means using the marks as positional references.

A radiation image reading device includes: a light scanning unit; a light detection unit. Each of a transmittance when the excitation light reflected from the surface of the recording medium is transmitted through the optical filter and a transmittance when the signal light emitted from the surface of the recording medium at an angle larger than a predetermined angle with respect to a direction perpendicular to the scan line within the detection surface is transmitted through the optical filter is smaller than a transmittance when the signal light emitted from the surface of the recording medium at an angle smaller than the predetermined angle with respect to a direction perpendicular to the scan line within the detection surface is transmitted through the optical filter.

A mobile radiography system includes a wheeled transport frame and a vertical column mounted on the transport frame. A telescoping arm is attached to the vertical column and to an x-ray tube head. The telescoping arm allows an operator to rotate the tube head to a desired orientation and then to fix the tube head in the desired orientation without mechanical impact noise. A permanent magnet and an electromagnetic coil assembly allows an operator to easily and quietly control rotation of the tube head.

A mobile radiography system includes a wheeled transport frame and a vertical column mounted on the transport frame. A boom is attached to the vertical column and to an x-ray tube head. A boom carriage allows movement of the boom along a track in the vertical column and includes a magnetic mechanism to lock the boom in the track at a desired height. An electromagnetic coil in the boom carriage is configured to disable the magnetic lock mechanism to allow vertical movement of the boom along the track.

A method for measuring an X-ray image of an area undergoing medical examination that has at least one object. A 3D model is provided of the area undergoing examination that includes a virtual 3D object to be assigned to the object to be measured, a digitally reconstructed X-ray picture is computed based on the 3D model and under the assumption of a virtual projection direction, the X-ray image is compared with the digitally reconstructed X-ray picture, the virtual projection direction is changed relative to the virtual 3D object. The steps of comparing and changing are repeated until a virtual projection direction with maximum correlation between the X-ray image and the digitally reconstructed X-ray picture is found. An object plane is determined that is to be assigned to the virtual 3D object. A corrected projection direction is defined and the X-ray image is measured.

A device (200) includes a unit bracket weldment (201), a bridge weldment (202) extending from the unit bracket weldment to a plate bracket assembly (209), and an x-ray plate (203) extending distally from the plate bracket assembly. One or more cable hook weldments (211,212) are disposed to either side of the x-ray plate. A method of inspecting a cable (1102) or power line includes coupling the device to a drone (101). The drone can then be flown to capture the cable in the cable hook weldments such that an x-ray imager (1103) can capture one or more of x-ray images of the cable or power line.
