摘要： A stackable rack may comprise: at least two rails, a cross-section of each rail having a shape resembling a staircase, first step portion of which represents a first surface upon which a reflector can be disposed; and a second step portion of which represents a second surface which can support another rail. A method of making a narrow band x-ray filter may comprise: providing a substrate; and stacking one or more reflection units in succession upon the substrate, each reflection unit including a rack (such as mentioned above) and a reflector held by the rack. An apparatus to produce a substantially narrow band x-ray beam may include such a filter. An apparatus to make an x-ray image of a subject may include: the apparatus to produce a substantially narrow band x-ray beam, e.g., as set forth above, and an x-ray detector arranged to receive the narrow band x-ray.

摘要： The X-ray examination apparatus (1) comprises and X-ray source (2), an X-ray detector (5) and an X-ray filter (6) which is located between the X-ray source (2) and the X-ray detector (5). The X-ray filter (6) includes filter elements (7), notably capillary tubes, and the X-ray absorption of separate filter elements can be controlled by controlling a quantity of X-ray absorbing liquid (32) in the respective filter elements (7). The quantity of X-ray absorbing liquid in the individual filter elements is controlled by way of electric voltages applied to the individual filter elements. The filter elements (7) are formed as spaces between deformed foils (10) which are arranged in a stack which is expanded in the direction transversely of the foils. Adjacent foils are locally attached to one another along seams (30). The stack is arranged between rigid plates (11) and buffer elements (12) are provided between the rigid plates and the stack. The buffer elements are contractable in the direction transversely of the direction of expansion of the stack. The shape of the cross section of the capillary tubes is dependent on the ratio of the width of the seams to the spacing of the seams.

摘要： An X-ray examination apparatus (1) comprises a filter (4) which is arranged between the X-ray source (2) and the X-ray detector (3). The X-ray filter comprises a large number of filter elements (5); the X-ray absorptivity of said filter elements can be adjusted by controlling the quantity of X-ray absorbing liquid (6) in the filter elements. The filter elements are formed by metal capillary tubes, or the wall of the capillary tubes is provided with a metal layer (7). On the metal layer there is provided a dielectric layer (8) and the dielectric layer is covered by a coating layer (9). The dielectric layer is, for example a glass, parylene or polystyrene layer. The coating layer is, for example a Teflon, silane of siloxane layer. The dielectric layer can be dispensed with when a Teflon coating layer is used.

摘要： An X-ray examination apparatus in accordance with the invention comprises a filter (4) for limiting the dynamic range of an X-ray image which is formed on an X-ray detector (4) by irradiation of an object (3), for example a patient to be examined, by means of X-rays (15). The filter (4) comprises filter elements (5), being capillary tubes (5), one end of which communicates with an X-ray absorbing liquid. The adhesion of the X-ray absorbing liquid to the inner side of the capillary tubes is adjustable by means of an electric voltage which can be applied to an electrically conductive layer (36) provided on the inner side of the capillary tubes (5). The filling of the capillary tubes (5) with the X-ray absorbing liquid is adjusted on the basis of the period of time during which the electric voltage is applied. This period of time can be subdivided into a number of fractions and individual rows of capillary tubes are then filled with the X-ray absorbing liquid partly in parallel.

摘要： An imaging system spatially modulates penetrating radiation that passes through an object under investigation. The modulation introduces spatial irregularities which can be deflected while passing through the object under investigation. The deflection of each irregularity can be identified and is converted into contrast of a projection of the object. One embodiment of the invention includes: a source of penetrating radiation (1), and a modulator (3) for the creation of spatial irregularities; and a detector (5) for the measuring of transverse translations of spatial irregularities and converting the measured transverse translations into contrast in a projection (8) of object (4).
