Abstract: An x-ray apparatus (1), has an electron beam source (2), a target (4), onto which the electron beam (3) is directed to form a focal spot (5; 5a, 5b) on the target (4), x-ray optics (6) for collecting x-rays emitted from the focal spot (5; 5a, 5b) to form an x-ray beam (8) and a sample position (9) at which the x-ray beam (8) is directed. The x-ray apparatus (1) further includes an electrostatic or electromagnetic electron beam deflection device (10) suitable for moving the focal spot (5; 5a, 5b) on the target (4). The extension of the focal spot (5; 5a, 5b) in any direction (x, y, z) is at least a factor of 1.5 smaller than the extension of the target (4). An x-ray apparatus is thereby provided with simplified alignment of the x-ray optics with respect to a microfocus x-ray source.

Abstract: Among other things, one or more techniques and/or systems are described for reducing a voltage ripple in an electric signal. In this way, in radiographic imaging modalities, for example, undesired fluctuations in an output of a radiation source (e.g., undesirable fluctuations in an energy level of emitted photons) may be reduced. To reduce the voltage ripple, a (ripple reducing) electric signal is generated that comprises properties substantially similar to the voltage ripple, but opposite in phase. The (ripple reducing) electric signal is then combined with the original electric signal to generate a combined electric signal with a voltage ripple that is reduced relative to the voltage ripple of the electric signal as initially generated.

Abstract: One provides (101 and 102) two or more X-ray sources (202 and 204) that are independent and discrete from one another. By one approach, these X-ray sources emit corresponding X-rays (203 and 205) using different voltage levels. In particular, these voltage levels can be sufficiently different from one another to readily permit different elements as comprise an object (201) being examined to be distinguished from one another. These X-rays are then emitted (106) from these sources and towards an object to be examined while causing relative motion (207) between such sources on the one hand and the object on the other.
