摘要： The inventive device relates to means for X-ray therapy of malignant and non-malignant growths and other diseases and comprises a hollow probe (5), a radiation source (1) of neutral particles irradiated in the form of X-ray or gamma-ray quantum or neutrons and a unit for forming the particle beam of said radiation which is directed along the longitudinal axis of the probe. The inventive means for forming the particle beam is partially embodied in the form of a collimator or a lens (18) which is embodied in the form of a set of curved channels for transmitting radiation with total internal reflection. Said means can be arranged inside the probe (5). The inventive probe is used by introduction thereof into a patient body (11) and bringing the distal end thereof to a pathologic area (13) or by introducing the end directly into said area. In order to affect the pathologic area, the radiation emitted by the source of neutral particles or the secondary radiation excited in a target which is arranged in the distal end of the probe, or the radiation diffused by said target are used. The structure of the inventive device does not require vacuum pumping of the probe and the use of high voltage therein. The structural design is easily transformed by changing the probe, in particular for modifying the dimension thereof, and the energy and direction of the radiation acting on the pathologic area. The demountable embodiment of the probe simplifies the sterilisation thereof.

摘要： The inventions make possible to increase the degree of radiation focusing by the lens, to use particles of higher energies, and to increase the coefficients, depending on these factors, of the devices, the lens is used in. Thus the sublens 18 of the least degree of integration represents a package of the channels 5, which is growing out of joint drawing and forming the capillaries, which are laid in a bundle. The sublens of each higher degree of integration represents a package of sublenses of the previous degree of integration, which is growing out of their joint drawing and forming. The sublenses are growing out of performing the said operations at the pressure of the gaseous medium inside the channels being higher than the pressure in the space between the sublenses of the previous degree of integration and at the temperature of their material softening and splicing the walls. To produce the lenses a bundle of stocks (capillaries) in a tubular envelope is fed to the furnace (at the first stage) or stocks, produced on the previous degree, and the said bundle is drawing from the furnace at the speed, exceeding the speed of feeding. The product is cut off on stocks for the next stage, and at the final stage the product is formed by varying the drawing speed, after what the parts with formed barrel-shaped thickenings are cut of. 6 independent and 41 dependent claims of the formula, 30 fig. drawings.

摘要： With this invention, it is possible to divert or focus beams, convert divergent beams to quasi-parallel beams and vice versa, and to filter and monochromatize beams. Energy losses in radiation transport are reduced, the useful energy spectrum is broadened, and the concentration of the radiation increased. Large-scale sources can be used without any reduction in the proportion of particles captured and the radiation spectrum can be controlled. To achieve this, the method involves, in addition to the repeated reflection of particles as they interact with alternating media of differing densities, the diffused and potential scattering or interference of the particles diffracted by multiple-layer structures created on reflecting surfaces. The proposed device is provided with a coating of such surfaces in layers with differing electromagnetic properties. The optical system is designed preferably as a set of miniature lenses or half-lenses (28) consisting of a plurality of capillaries or polycapillaries; a suitable coating (22) is applied to the walls of the channels (24) of these capillaries. This arrangement eliminates the need for supporting structures for shaping the profiles of the optical system.

摘要： The inventive X-ray microscope comprises an extended X-ray source, a unit for placing a studied object (3), a recording unit and an X-ray capillary lens disposed therebetween. The channels of said lens are divergent in the direction of the recording unit. The unit for placing the studied object is disposed between the extended X-ray source and the smallest end of the X-ray capillary lens. The inventive device is characterised in that the walls of the channels (14, 16) for transmitting radiation are coated with or made of a material which absorbs or scatters X-ray radiation, and are shaped in the form of the lateral surface of a frustum of cone or pyramid, or of a truncated cylinder or prism. Said material excludes the effect of total external reflection. The straightness of the longitudinal axes of the channels makes it possible to use said channels as collimators. The resolution capability totally depends on technological capabilities to reduce the input size of the channels. The use of the extended X-ray source makes it possible to significantly reduce the time of exposure and the power of an X-ray tube.

摘要： The invention relates to studying and testing substances, materials or instruments with the aid of x-ray emissions. A system for studying in the x-ray radiation spectrum simultaneously using several analytical devices, comprises a source (1) of divergent x-ray radiation, channels for transmitting the radiation to the analytical devices (5) and an apparatus thereof for spectrometric, diftactometric and other studies, for producing pictures of the internal structure of objects, and for x-ray lithography etc. The radiation is transmitted to the devices (5) by means of quasi-parallel beams (4) formed by x-ray hemi-lenses (2) which are embodied in the form of a set of bent channels whose inner walls are used for multiple total external reflection of x-rays. Radiation beams (35) directed to several analytical devices (5) can also be produced with the aid of the common hemi-lens (2) and whose output beam is broken into several beams with the aid of monochromates (33) placed on the path of an initial beam (4) at an angle to the direction of the diffusion thereof. Each of said beams intercepts a part (34) of the cross-section of the initial beam.

摘要： The inventions relate to a group that includes means for directing charged particles, enabling the acceleration and interaction thereof, and producing radiation caused by their movement, namely a method for changing the direction of an accelerated charged particle beam, a device for implementing said method, a source of undulator electromagnetic radiation, a linear and a circular charged particle accelerator, and a collider and means for producing a magnetic field created by a stream of accelerated charged particles. The method and the device for implementing same are based on the use of a curved channel (1) for transporting particles, which is made from a material that is able to be electrically charged, and the formation of the same kind of charge on the inside surface of the channel wall as that of the particles. The characterizing feature of these inventions is that they require the maintenance of a condition that relates the energy and the charge of the particles to the geometrical parameters of the channel, in particular the radius R of curvature of the longitudinal axis (14) thereof, and to the electrical strength of the wall material. The other devices in this group include a device for changing the direction of a beam, which defines the trajectory of the particles inside these devices to produce the required shape according to the function of the corresponding device and focuses the beam. The technical result is the possibility of rotating the beam through large angles without loss of intensity, significantly simplifying the design, and also reducing the mass and dimensions of all the devices, particularly by obviating the need for magnets and supply voltage and control voltage sources for such devices.

摘要： The localization of a cancellation cancer detected by a previous diagnosis is carried out in the first stage of a radiation therapy by scanning a part (7) of a body (5) where said cancellation cancer is sited. The scanning is carried out by moving a zone (4) of radiation concentration formed by crossing several roentgen beams. Data on the spissitude of a tissue is received with the aid of detectors (6), to which the secondary radiation produced in the zone (4) of concentration is transferred. In the second stage, scanning with the aid of the same means for creating roentgen beams, which are used in the first stage, is carried out by moving the zone of concentration within the limits of cancellation cancer which are defined in the first stage. X-ray emitters are switched to an increased rate of operation with the aid of a control unit making it possible to perform radiolesion of the cancellation cancer. Various combinations of collimators, roentgen lenses and hemilenses creating a roentgen optical system together with the sources of radiation and detectors are used in order to transmit the X-rays to the zone of concentration, and the secondary radiation to the detectors. A relative motion (10a, 10b) of the roentgen optical system (8) as a its whole and the body of a patient (5) is performed during the scanning. XY sensors (11) recording said motion and the outputs of the detectors (6) are connected outputs to a unit (12) for data processing and display. The inventive method for obtaining information on the spissitude of a biological tissue and the use of the same means for forming roentgen beams in both stages increase the accuracy of measurements and the precision of the radiation effect and decrease the dose of exposure of the healthy tissue.

摘要： The present inventions provide for bending the beams, their focusing, transforming a divergent radiation into a quasi-parallel one, and vice versa, its filtering and monochromatization. There are also attained reduced radiation transfer losses, extended range of energies used, and higher radiation concentration. A possibility is provided for use of larger radiation sources without decreasing the proportion of the captured particles, as well as for controlling the radiation spectrum. With this purpose in view, provision is made in the proposed method, apart from multiple reflection of particles upon interaction with different-density alternating media, also for diffuse and potential scattering or interference of particles that diffract on multilayer structures applied to reflecting surfaces. In a device carrying the proposed method into effect the aforementioned surfaces are coated with layers differing in electromagnetic properties. The optical system of the device appears principally as a set of miniature lenses or hemilenses 28, built up of a plurality of capillaries or polycapillaries, the walls of whose channels 24 are provided with an appropriate coating 22. No use of any support structures for forming the profiles of the optical system is required.

摘要： The inventive device comprises an X-ray tube (1) provided with a planar fire anode (2). A first collimator (5) having perforated channels (4) is disposed between said X-ray tube and a studied object (8). A unit (16) provided with a detector array (17) detects secondary radiation which is excited in the object (8). A second collimator provided with perforated or slotted channels (23) is arranged between said object and the unit (16). The location of the radiation spot (3) of the X-ray tube (1) on the surface of the anode (2) is scanned with the aid of a electron beam control unit (6). A signal carrying information on the density of substance of the object (8) appears in the cross-section between the continuation of the channel of the first collimator on whose input the radiation of the tube (1) is present and the continuation of one of channels of a second collimator (9). Said signal reaches the input (18) of a data processing block (19.1) which is embodied in the form of part of a data processing and display unit (19). Information on the current position of electron beam is transmitted from a unit (6) to the input (20) of the block (1.91). In another variant, such data is contained in the beam modulation of the tube (1), the connection between the unit (6) and the block (1.91) being absent. The distribution of the density of the substance through the volume of the object (8) is determined in the block (1.91). The result is displaced on a monitor (19.2). The inventive device can also comprise an additional collimator (9a) and a means (16a) provided with a detector (17a), a means (28) for detecting the radiation of the tube (1) which passes through the object (8) and for producing the projection (29) of the internal structure thereof.
