[0021] X-ray capillary system
[0022] Figure 1 An X-ray capillary system 100 according to an embodiment is schematically shown. 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, referring to Figure 1, the X-ray capillary device 110 may include one or more networks each consisting of a plurality of interconnected capillary segments (e.g., three networks 111, 112, 113 as shown). In one embodiment, each of the three networks 111, 112, 113 of the X-ray capillary device 110 may include a plurality of interconnected capillary segments. For example, the network 111 may include five capillary segments (1,1), (1,2), (1,3), (1,4), (1,5). Figure 2 An enlarged view of network 111 is shown.
[0025] In one embodiment, referring 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, the end is called an open end. If one end of a capillary segment is connected to any end of any other capillary segment, the end is called an interconnected end.
[0026] For example, refer to Figure 2 , end (1,1,1) of capillary segment (1,1) is an open end because it is not connected to any end of any other capillary segment; end (1,1,2) of capillary segment (1,1) is an interconnected end because it is connected to end (1,3,1) of capillary segment (1,3).
[0027] The capillaries merge downstream
[0028] In one embodiment, referring to Figure 1 and Figure 2 , each network of the X-ray capillary device 110 can include at least (A) a first capillary segment having a first open end and a first interconnected end, (B) a second capillary segment having a second open end and a second interconnected end, and (C) a third capillary segment having a third open end and a third interconnected end.
[0029] For example, the network 111 includes (A) a first capillary segment (1,1) having a first open end (1,1,1) and a first interconnected end (1,1,2), (B) a second capillary segment (1,2) having a second open end (1,2,1) and a second interconnected end (1,2,2), and (C) a third capillary segment (1,3) having a third open end (1,3,2) and a third interconnected end (1,3,1).
[0030] In addition, in one embodiment, each network of the X-ray capillary device 110 can (A) allow the first X-ray from the X-ray source 120 to enter each network through the first open end, and then (B) guide the first X-ray in the first capillary segment from the first open end to the first interconnected end, and then (C) guide the first X-ray from the first interconnected end directly or through the interior of one or more capillary segments of each network to the third interconnected end, and then (D) guide the first X-ray in the third capillary segment from the third interconnected end to the third open end, and then guide the first X-ray to leave each network through the third open end.
[0031] For example, the network 111 (A) allows X-rays (1, 1) from the X-ray source 120 to enter the network 111 via the first open end (1, 1, 1), then, (B) guides the X-rays (1, 1) within the first capillary segment (1, 1) from the first open end (1, 1, 1) to the first interconnected end (1, 1, 2), then, (C) guides the X-rays (1, 1) from the first interconnected end (1, 1, 2) directly to the third interconnected end (1, 3, 1), then, (D) guides the X-rays (1, 1) within the third capillary segment (1, 3) from the third interconnected end (1, 3, 1) to the third open end (1, 3, 2), and then, guides the X-rays (1, 1) to leave the network 111 via the third open end (1, 3, 2).
[0032] In addition, in one embodiment, each network of the X-ray capillary device 110 can (A) allow the second X-ray from the X-ray source 120 to enter each network through the second open end, and then (B) guide the second X-ray in the second capillary segment from the second open end to the second interconnected end; then, (C) guide the second X-ray from the second interconnected end directly or through the interior of one or more capillary segments of each network to the third interconnected end, and then, (D) guide the second X-ray in the third capillary segment from the third interconnected end to the third open end, and then guide the second X-ray to leave each network through the third open end.
[0033] For example, the network 111 (A) allows X-rays (1, 2) from the X-ray source 120 to enter the network 111 via the second open end (1, 2, 1), then, (B) guides the X-rays (1, 2) within the second capillary segment (1, 2) from the second open end (1, 2, 1) to the second interconnected end (1, 2, 2), then, (C) guides the X-rays (1, 2) from the second interconnected end (1, 2, 2) through the interior of the capillary segment (1, 4) to the third interconnected end (1, 3, 1), then, (D) guides the X-rays (1, 2) within the third capillary segment (1, 3) from the third interconnected end (1, 3, 1) to the third open end (1, 3, 2), and then, guides the X-rays (1, 2) to leave the network 111 via the third open end (1, 3, 2).
[0034] In short, each of the networks 111, 112, 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. Figure 2 The network 111 guides two independent X-rays (1, 1) and (1, 2) through the X-ray capillary device 110 to reach the open end (1, 3, 2).
[0035] In one embodiment, the ability of the networks 111 , 112 , 113 to guide X-rays through the interior of their capillary segments may be based on the effect of total reflection of the X-rays by the interior smooth surfaces of the capillary segments.

[0037] In one embodiment, referring 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, which enter the three networks 111, 112, and 113 through the nine open ends on the left side of the X-ray capillary device 110. Then, the three networks 111, 112, and 113 guide the X-rays through the X-ray capillary device 110, and then, leave the X-ray capillary device 110 through the 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, the source point 150 may be used as an X-ray point source for X-ray imaging.

[0040] Figure 3 shows a summary according to an embodiment Figure 1 Flowchart 300 of 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 the X-ray source through all open ends of the capillary segments of the M networks except the open end (i, 3, 2) (i=1, ..., M), then (B) leave the M networks through the open end (i, 3, 2) (i=1, ..., M), and then (C) reach the source point. For example, in the above embodiment, refer to Figure 1 and Figure 2 , the X-ray source 120 emits X-rays, which (A) enter the three networks 111, 112, and 113 from the X-ray source 120 through the nine open ends on the left side of the X-ray capillary device 110, then (B) leave the three networks 111, 112, and 113 through the three open ends on the right side of the X-ray capillary device 110, and then (C) reach the source point 150.

In other words, X-rays entering each network through each of all open ends of each network except the exit open end will be guided by each network and leave each network only through the exit open end.
[0045] For example, for the network 111, the open end (1,3,2) is the only open end as an exit. In other words, the X-rays entering the network 111 through the open ends (1,1,1), (1,2,1), (1,5,1) will be guided by the network 111 and leave the network 111 only through the exit open end (1,3,2).

[0049] In one embodiment, if the capillary section of the X-ray capillary device 110 is required to be a pore in a matrix, the three networks 111, 112, 113 formed above can be embedded in the matrix, and then the materials of the three networks 111, 112, 113 formed above can be dissolved and removed.
[0050] At least 2 capillary connections downstream

[0052] By definition, a capillary junction is where at least three interconnected ends, respectively belonging to three capillary segments, meet.
[0053] For example, refer to Figure 2 , on the path of the X-ray (1, 2) within the network 111, there are two capillary joints 111a and 111b.
[0054] Fresnel Zone Plate
[0055] In one embodiment, referring to Figure 1 The X-ray capillary system 100 may include a Fresnel zone plate 130 configured to (A) receive X-rays leaving 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 (B) converge the X-rays to a source point 150 .

[0057] In one embodiment, referring to Figure 1 , the X-ray capillary system 100 may include a reflector 140 configured to reflect X-rays from the 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 (eg, Figure 1 shown).
[0058] The open ends except the exit open end surround the X-ray source
[0059] Alternatively, refer to Figure 1 and Figure 4 , all open ends of the X-ray capillary device 110 except the outlet open end (ie, Figure 1 The 9 non-exit open ends of the X-ray capillary device 110 located on the left side can surround the X-ray source (such as Figure 4 As shown), for any plane intersecting the X-ray source 120, all open ends of the X-ray capillary device 110 except the outlet open end are located on both sides of the any plane.
[0060] For example, refer to Figure 4 , for the line intersecting the X-ray source 120 and perpendicular to Figure 4 In the plane 410 of the page, the 9 non-exit open ends of the X-ray capillary device 110 on the left are located on both sides of the plane 410.
