Abstract: An x-ray tube source is disclosed that allows differential phase shift, attenuation, and x-ray scattering features of an object to be acquired in a single exposure. Such multiplexed x-ray tube source includes multiple x-ray spot origins controlled in such a way that each slightly separated spot is temporally modulated “ON and OFF” at differing frequencies. In an x-ray interferometer system, such x-ray tube source forms multiple illumination beams of a single angular view of an object's feature but each with different interference fringe locations. A composite image can be acquired with a high frame-rate digital detector as a component element in such x-ray interferometer system. Such composite image can be subsequently de-multipexed and separately presented according to each spot-source illumination beam. Such isolated images of an object's feature, each having different fringe locations, allows for post-acquisition “fringe-mapping” analysis of the feature's full interaction with x-rays, including refraction, scattering, and absorption.

Abstract: An x-ray illumination beam system includes an electron emitter and a target having one or more target microstructures. The one or more microstructures may be the same or different material, and may be embedded or placed atop a substrate formed of a heat-conducting material. The x-ray source may emit x-rays towards an optic system, which can include one or more optics that are matched to one or more target microstructures. The matching can be achieved by selecting optics with the geometric shape, size, and surface coating that collects as many x-rays as possible from the source and at an angle that satisfies the critical reflection angle of the x-ray energies of interest from the target. The x-ray illumination beam system allows for an x-ray source that generates x-rays having different spectra and can be used in a variety of applications.

Abstract: An x-ray diffraction system includes an x-ray source having a first interchangeable x-ray generating component, a second interchangeable x-ray generating component, an actuator and a controller operatively connected to the actuator. The first and second interchangeable x-ray generating components are interchangeable with one another. The actuator is operatively connected to the first and second interchangeable x-ray generating components. A method for non-destructive x-ray diffraction includes emitting a first x-ray beam from an x-ray source with a first interchangeable x-ray generating component based on a first desired depth to measure a crystallographic signature of a sample at the first desired depth, interchanging the first interchangeable x-ray generating component with a second interchangeable x-ray generating component to form a modified x-ray source, and emitting a second x-ray beam from the modified x-ray source based on a second desired depth, to non-destructively measure a crystallographic signature of the sample at the second desired depth.

Abstract: A rotatable anode target for an X-ray tube (1) of the present invention includes a metallic disc (2) which includes a first crystal structure; a metallic cylinder (3) which is joined with the metallic disc and includes a second crystal structure, where a first average aspect ratio of first crystal grains positioning at a first region within 2 mm from a interface between the metallic disc and the metallic cylinder is less than 2, and a second average aspect ratio of second crystal grains positioning at a second region within 2 mm from the interface is 2 or more and 8 or less. It is thereby possible to provide an X-ray tube target which has high heat release performance and where thermal deformation is difficult to occur.

Abstract: In a high-voltage apparatus according to this invention, a predetermined voltage is applied to a rotating anode after waiting until the number of rotations increases to such an extent that the rotating anode is not damaged. That is, X-rays of desired intensity are already outputted from a point of time when the voltage is applied to the rotating anode. Therefore, diagnosis can be performed immediately after the voltage is applied to the rotating anode. That is, unlike the prior art, there is no need to wait until X-ray intensity becomes suitable for diagnosis after X-ray emission is started, and there is no need to irradiate the patient with unnecessary X-rays. Therefore, the patient can be inhibited from being irradiated with excessive X-rays (with an improvement made in a response from when the operator gives instructions for starting fluoroscopy until emission of X-rays suitable for diagnosis).

Abstract translation: 在根据本发明的高电压装置中，在等待直到转数增加到旋转阳极未被损坏的程度之后，将预定电压施加到旋转阳极。 也就是说，从施加到旋转阳极的电压的时刻起已经输出了所需强度的X射线。 因此，可以在将电压施加到旋转阳极之后立即进行诊断。 也就是说，与现有技术不同，在X射线发射开始之后，不需要等待X射线强度变得适合于诊断，并且不需要向患者照射不必要的X射线。 因此，可以抑制患者被过量的X射线照射（当从操作者给出用于开始荧光透视的指示直到发射适合于诊断的X射线时的响应而改善）。

Abstract: The X-ray tube having a rotating and linearly translating anode includes an evacuated shell having a substantially cylindrical anode rotatably mounted therein. The substantially cylindrical anode may be rotated through the usage of any suitable rotational drive, and the substantially cylindrical anode is further selectively and controllably linearly translatable about the rotating longitudinal axis thereof. A cathode is further mounted within the evacuated shell for producing an electron beam that impinges on an outer surface of the substantially cylindrical anode, thus forming a focal spot thereon. X-rays are generated from the focal spot and are transmitted through an X-ray permeable window formed in the evacuated shell.
