Detailed Implementation Methods
[0021] X-ray capillary system
[0022] Figure 1 An X-ray capillary system 100 according to an embodiment is schematically illustrated. In one embodiment, the X-ray capillary system 100 may include an X-ray capillary device 110 and an X-ray source 120. In one embodiment, the X-ray source 120 may generate monochromatic X-rays.
[0023] X-ray capillary device
[0024] In one embodiment, refer to Figure 1The X-ray capillary device 110 may include one or more networks, each consisting of multiple interconnected capillary segments (e.g., the three networks 111, 112, and 113 shown in the figure). In one embodiment, each of the three networks 111, 112, and 113 of the X-ray capillary device 110 may include multiple interconnected capillary segments. For example, network 111 may include five capillary segments (1,1), (1,2), (1,3), (1,4), and (1,5). Figure 2 An enlarged view of network 111 is shown.
[0025] In one embodiment, refer to Figure 1 and Figure 2 Each capillary segment of the X-ray capillary device 110 may have two ends. If one end of a capillary segment is not connected to any end of any other capillary segment, that end is called an open end. If one end of a capillary segment is connected to any end of any other capillary segment, that end is called an interconnecting end.
[0026] For example, refer to Figure 2 The end (1,1,1) of the capillary segment (1,1) is an open end because it is not connected to any end of any other capillary segment; the end (1,1,2) of the capillary segment (1,1) is an interconnecting end because it is connected to the end (1,3,1) of the capillary segment (1,3).
[0027] Capillaries converge downstream
[0028] In one embodiment, refer to Figure 1 and Figure 2 Each network of the X-ray capillary device 110 may include at least (A) a first capillary segment having a first open end and a first interconnecting end, (B) a second capillary segment having a second open end and a second interconnecting end, and (C) a third capillary segment having a third open end and a third interconnecting end.
[0029] For example, network 111 includes (A) a first capillary segment (1,1) having a first open end (1,1,1) and a first interconnect end (1,1,2), (B) a second capillary segment (1,2) having a second open end (1,2,1) and a second interconnect end (1,2,2), and (C) a third capillary segment (1,3) having a third open end (1,3,2) and a third interconnect end (1,3,1).
[0030] Furthermore, in one embodiment, each network of the X-ray capillary device 110 may (A) allow a first X-ray from the X-ray source 120 to enter each network via a first open end, then (B) guide the first X-ray within a first capillary segment from the first open end to a first interconnect end, then (C) guide the first X-ray from the first interconnect end directly or through the interior of one or more capillary segments of each network to a third interconnect end, then (D) guide the first X-ray within a third capillary segment from the third interconnect end to a third open end, and then guide the first X-ray to exit each network via the third open end.
[0031] For example, network 111(A) allows X-rays (1,1) from X-ray source 120 to enter network 111 via a first open end (1,1,1), then (B) guides X-rays (1,1) in a first capillary segment (1,1) from the first open end (1,1,1) to a first interconnect end (1,1,2), then (C) guides X-rays (1,1) directly from the first interconnect end (1,1,2) to a third interconnect end (1,3,1), then (D) guides X-rays (1,1) in a third capillary segment (1,3) from the third interconnect end (1,3,1) to a third open end (1,3,2), and then guides X-rays (1,1) to leave network 111 via the third open end (1,3,2).
[0032] Furthermore, in one embodiment, each network of the X-ray capillary device 110 may (A) allow a second X-ray from the X-ray source 120 to enter each network via a second open end, and then (B) guide the second X-ray within a second capillary segment from the second open end to a second interconnect end; then (C) guide the second X-ray from the second interconnect end directly or through the interior of one or more capillary segments of each network to a third interconnect end; then (D) guide the second X-ray within a third capillary segment from the third interconnect end to a third open end; and then guide the second X-ray to exit each network via the third open end.
[0033] For example, network 111(A) allows X-rays (1,2) from X-ray source 120 to enter network 111 via the second open end (1,2,1), then (B) guides the X-rays (1,2) in the second capillary segment (1,2) from the second open end (1,2,1) to the second interconnect end (1,2,2), then (C) guides the X-rays (1,2) from the second interconnect end (1,2,2) through the interior of the capillary segment (1,4) to the third interconnect end (1,3,1), then (D) guides the X-rays (1,2) in the third capillary segment (1,3) from the third interconnect end (1,3,1) to the third open end (1,3,2), and then guides the X-rays (1,2) to leave network 111 via the third open end (1,3,2).
[0034] In short, each of the networks 111, 112, and 113 of the X-ray capillary device 110 is configured to guide at least two independent X-rays through the X-ray capillary device 110 to the end of a single capillary segment. For example, see reference... Figure 2 Network 111 guides two independent X-rays (1,1) and (1,2) through X-ray capillary device 110 to the open end (1,3,2).
[0035] In one embodiment, the ability of networks 111, 112, 113 to guide X-rays through the interior of their capillary segments can be based on the effect of total reflection of X-rays by the smooth interior surface of the capillary segments.
[0036] Operation of X-ray capillary systems
[0037] In one embodiment, refer to Figure 1 The X-ray capillary system 100 can operate as follows. In one embodiment, the X-ray source 120 can emit X-rays that enter three networks 111, 112, and 113 via nine open ends on the left side of the X-ray capillary device 110. The three networks 111, 112, and 113 then guide the X-rays through the X-ray capillary device 110, and then exit the X-ray capillary device 110 via three open ends on the right side of the X-ray capillary device 110, and then reach the source point 150.
[0038] In one embodiment, source point 150 can serve as an X-ray point source for X-ray imaging.
[0039] A flowchart summarizing the operation of an X-ray capillary system
[0040] Figure 3 An overview according to an embodiment is shown. Figure 1 Flowchart 300 for the operation of the X-ray capillary system 100.
[0041] In step 310, the operation may include emitting X-rays, which (A) enter the M networks from an X-ray source via all open ends of the capillary segments of the M networks except for the open ends (i,3,2) (i=1, ...,M), then (B) exit the M networks via the open ends (i,3,2) (i=1, ...,M), and then (C) reach the source point. For example, in the above embodiment, referring to... Figure 1 and Figure 2 X-ray source 120 emits X-rays, which (A) enter three networks 111, 112, and 113 from the X-ray source 120 via the nine open ends on the left side of the X-ray capillary device 110, and then (B) exit the three networks 111, 112, and 113 via the three open ends on the right side of the X-ray capillary device 110, and then (C) reach the source point 150.
[0042] Other embodiments
[0043] Each network has only one open egress port.
[0044] In one embodiment, refer to Figure 1 and Figure 2 Each of the three networks 111, 112, and 113 of the X-ray capillary device 110 has only one open end as an exit (referred to as the exit open end). In other words, X-rays entering each network via each of the other open ends of each network will be guided by each network and will exit each network only via the exit open end.
[0045] For example, for network 111, the open end (1,3,2) is the only open end that serves as the exit. In other words, X-rays entering network 111 via open ends (1,1,1), (1,2,1), and (1,5,1) will be guided by network 111 and will leave network 111 only via the exit open end (1,3,2).
[0046] Material of capillary section
[0047] In one embodiment, refer to Figure 1 and Figure 2 The capillary sections of the three networks 111, 112, and 113 of the X-ray capillary device 110 can be made of silica, ceramic, glass, or glass fiber. Alternatively, the capillary sections of the three networks 111, 112, and 113 of the X-ray capillary device 110 can be pores (not shown) within a substrate. In one embodiment, the substrate can be made of plastic.
[0048] In one embodiment, refer to Figure 1The X-ray capillary device 110 can be manufactured as follows. In one embodiment, multiple independent capillary segments can be fused together and then bundled together to form three networks 111, 112, and 113 of the X-ray capillary device 110.
[0049] In one embodiment, if the capillary section of the X-ray capillary device 110 is required to be a pore in the matrix, the three networks 111, 112, and 113 formed above can be embedded in the matrix, and then the material of the three networks 111, 112, and 113 formed above can be dissolved and removed.
[0050] There are at least two capillary joints downstream.
[0051] In one embodiment, refer to Figure 1 and Figure 2 For each of the three networks 111, 112, and 113 of the X-ray capillary device 110, there may be at least two capillary joints along a path of X-rays from the non-exit open end of each network to the exit open end of each network.
[0052] By definition, a capillary junction is the point where at least three interconnecting ends belonging to three separate capillary segments meet.
[0053] For example, refer to Figure 2 There are two capillary connectors 111a and 111b on the path of X-ray (1,2) within network 111.
[0054] Fresnel zone plate
[0055] In one embodiment, refer to Figure 1 The X-ray capillary system 100 may include a Fresnel zone plate 130 configured to (A) receive X-rays exiting three networks 111, 112, 113 via three open ends on the right side of the X-ray capillary device 110, and then (B) converge these X-rays to a source point 150.
[0056] reflector
[0057] In one embodiment, refer to Figure 1 The X-ray capillary system 100 may include a reflector 140 configured to reflect X-rays from an X-ray source 120 toward the X-ray capillary device 110. In one embodiment, the X-ray source 120 may be located between the reflector 140 and the X-ray capillary device 110 (e.g., Figure 1 (As shown).
[0058] Besides the open end of the export terminal, the open end surrounds the X-ray source.
[0059] alternative sites, refer to Figure 1 and Figure 4 All open ends of the X-ray capillary device 110 except for the outlet open end (i.e., Figure 1 The nine non-exit open ends of the X-ray capillary device 110 located on the left side can surround the X-ray source (e.g., in three-dimensional space) in three-dimensional space. Figure 4 As shown), such that for any plane intersecting with the X-ray source 120, all open ends of the X-ray capillary device 110, except for the outlet open end, are located on both sides of said any plane.
[0060] For example, refer to Figure 4 For the intersection with and perpendicular to the X-ray source 120 Figure 4 On plane 410 of the page, the nine non-exit open ends of the X-ray capillary device 110 located on the left side are located on both sides of plane 410. Specifically, six of the nine non-exit open ends are located above plane 410, and the remaining three of the nine non-exit open ends are located below plane 410.
