Abstract: The invention relates to an X-ray tube, especially a microfocus X-ray tube (2), comprising means (18) for orienting an electron beam (10) towards a target (4). A control device (20) is used to control the means for orienting the electron beam (10) towards the target (4) in such a way that the electron beam (10) scans the target (4), in addition to a measuring device (22) for measuring the intensity of the target current which flows to different scanning sites when the target (4) is scanned by the electron beam (10), or a measuring variable dependent on the target current, and an evaluation device (24) for associating each measured value of the target flow with the corresponding scanning site. Said X-ray tube enables the easy and economical implementation of a method for checking the operability of the target (4).

Abstract: A compact and low-cost electromagnetic wave generator in which X-rays having high intensity can be generated and the energy of generated X-rays can rapidly be switched. In an electromagnetic wave generator including a circular accelerator, a deflection electromagnet incorporated in the circular accelerator focuses injected and accelerated electrons. The circular accelerator produces stable closed electron orbits in respective regions with respective widths in the radial direction of the accelerator. The closed electron orbits are stable during injection and acceleration of electrons. A target is arranged across only some of the stable closed electron orbits so that a collision region, where a circulating electron beam collides with the target, and a non-collision region, where a circulating electron beam does not collide with the target, are produced. Through control of respective patterns of changes with time of the deflection magnetic field, a given electron closed orbit is shifted between the collision and the non-collision regions, thereby generating X-rays.

Abstract: An X-ray generator capable of reliably reducing an X-ray focal spot size without depending on the focal spot size of an electron beam on a target. Providing, within the irradiation range of an electron beam B of a target laminated structure 3 comprising a target 2 and an X-ray irradiation window 1, a low X-ray absorptivity region 3a of localized low X-ray absorptivity in the irradiation direction of the electron beam B results in the suppression of emission to the outside of X-rays from among the X-rays generated as a result of the irradiation of the electron beam B onto the target 2 that are from regions other than the low X-ray absorptivity region 3a, and an X-ray focal spot of a size corresponding to the size of the low X-ray absorptivity region 3a is obtained regardless of the size of the irradiation region of the electron beam B.

Abstract: An X-ray imaging method including the following steps is provided. An X-ray source is provided, wherein the X-ray source includes a housing, a cathode, and an anode target. The housing has an end window. The cathode is disposed in the housing, and the anode target is disposed beside the end window. The cathode is caused to provide an electron beam. A portion of the electron beam hits at least a part of areas of the anode target to generate an X-ray and the X-ray is emitted out of the housing through the end window. The X-ray is caused to irradiate an object to generate X-ray image information. An image detector is used to receive the X-ray image information.
