Abstract: A logging tool is for determining a property of a subsurface formation having a borehole therein and includes a housing to fit within the borehole. An x-ray generator is carried by the housing and includes at least three extractor electrodes, an electron emitter to emit electrons toward the extractor electrodes, and a target downstream of the extractor electrodes. The extractor electrodes have independently selectable potentials so as to allow direction of an electron beam, formed from the electrons emitted by the electron emitter, toward different longitudinal and lateral regions of the target, the target to emit x-rays into the subsurface formation when struck by the electron beam. A radiation detector is carried by the housing to detect incoming radiation resulting from interactions between the x-rays and the subsurface formation. Processing circuitry is coupled to the radiation detector to determine the property of the subsurface formation based upon detected incoming radiation.

Abstract: In an electron irradiation system, a gas-tight housing encloses a cathode region and an irradiation region, which communicate through at least an aperture. In the cathode region, there is arranged a high-voltage cathode for emitting an electron beam. In the irradiation region, there is an irradiation site arranged to accommodate a stationary or moving object to be irradiated. The migration of cathode-degrading debris is limited by means of an electric field designed to prevent positively charged particles from entering the cathode region via the aperture. The invention can be embodied with an axial electric field, which realizes an energy threshold, or a transversal field which deflects charged particles away from trajectories leading into the cathode region.

Abstract: Described here is a method for performing phase contrast imaging using an array of independently controllable x-ray sources. The array of x-ray sources can be controlled to produce a distinct spatial pattern of x-ray radiation and thus can be used to encode phase contrast signals without the need for a coded aperture. The lack of coded aperture increases the flexibility of the imaging method. For instance, because a fixed, coded aperture is not required, the angular resolution of the imaging technique can be increased as compared to coded-aperture imaging. Moreover, the lack of a radioopaque coded aperture increases the photon flux that reaches the subject, thereby increasing the attainable signal-to-noise ratio.

Abstract translation: 这里描述了使用独立可控x射线源的阵列进行相位对比成像的方法。 可以控制x射线源的阵列以产生X射线辐射的不同的空间图案，并且因此可用于对相位差信号进行编码，而不需要编码孔径。 编码孔径的缺乏增加了成像方法的灵活性。 例如，由于不需要固定的编码孔径，与编码孔径成像相比，可以增加成像技术的角度分辨率。 此外，缺乏无辐射光编码孔径增加了到达对象的光子通量，从而增加了可达到的信噪比。
