DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The following detailed description relates to various embodiments of a system (e.g., an x-ray imaging system) and an x-ray tube included therein. The x-ray tube includes an x-ray tube insert that is disposed within an x-ray casing or housing (not shown) of the x-ray tube. A vacuum is created within the x-ray tube insert during manufacture of the x-ray tube. To create the vacuum, a first end of the vacuum tube is connected to a support plate or center frame of the x-ray tube insert. A second end of the vacuum tube is connected to a vacuum pump through a connecting tube or extension tube. A vacuum is created within the x-ray tube insert using the vacuum pump. After the vacuum is created, the vacuum tube is sealed to enclose the vacuum environment of the x-ray tube insert. In another embodiment, a first end of the vacuum tube is connected to a support plate or center frame of the x-ray tube insert and a second end of the vacuum tube is connected to a vacuum pump without the use of a connecting tube or extension tube.

[0012] In some examples, a socket is used to connect the first end of the vacuum tube to the support plate. Additionally, an adapter can be used to couple the second end of the vacuum tube to the first end of the extension tube. In some examples, the second end of the extension tube is coupled to the vacuum pump using a fitting having multiple fasteners.

[0013] An X-ray system is shown in FIG. 1. The X-ray system includes an X-ray tube coupled to an X-ray controller capable of generating X-rays. FIG. 2 shows a schematic diagram of a vacuum processing assembly used to create a vacuum environment within an X-ray tube insert of an X-ray tube.

[0014] 2-8 show example configurations depicting the relative positional relationships of various components. When elements are shown as being in direct contact with or directly coupled to one another, such elements can, in at least one embodiment, be referred to as being in direct contact with or directly coupled to one another, respectively. Similarly, elements shown as being contiguous or adjacent to one another can, in at least one embodiment, be contiguous with or adjacent to one another, respectively. As an example, components in surface contact with one another can be referred to as being in surface contact. As another example, elements positioned apart from one another can be referred to as being apart from one another, in at least one embodiment, if there is only a space between the elements and no other components are present. Also, as another example, elements shown above / below one another, opposite one another, or to the left / right of one another can be referred to as above / below, opposite one another, or left / right elements with respect to one another. Additionally, as shown in the figures, in at least one embodiment, a top element or a topmost point of an element can be referred to as the "top" of the element, and a bottom element or a bottommost point of an element can be referred to as the "bottom" of the element. As used herein, top / bottom, upper / lower, above / below are relative to the vertical axis of the figure and are used to describe the location of elements of the figure relative to one another. Thus, elements shown on top of other elements are, by way of example, vertically positioned on top of the other elements. As yet another example, the shapes of elements shown in the figures can be referred to as having those shapes (e.g., circular, straight, flat, curvilinear, rounded, chamfered, angled, etc.). Furthermore, elements shown intersecting one another can, at least in one example, be referred to as intersecting elements or intersecting one another. Furthermore, elements shown within or outside of another element can, in one example, be referred to as shown within or outside of another element.

[0015] FIG. 1 illustrates an X-ray system 100 designed to generate X-rays to image a subject or object 102. The X-ray system 100 in FIG. 1 may be configured as an imaging system (e.g., a computed tomography (CT) system, a radiography system, a fluoroscopy system, an interventional system, a tomography system, etc.). However, the X-ray system 100 may be applied outside the fields of imaging and medical equipment. For example, the X-ray system 100 may be applied as a crystallography system, a security scanner, an industrial scanner, a non-destructive testing application, a radiography system, etc. In an example of an imaging system, the X-ray system 100 may be configured to image an object or subject 102 (e.g., a patient, an inanimate object, baggage, a pipeline, one or more manufacturing parts, and / or a foreign object, etc.).

[0016] The X-ray system 100 may include at least one X-ray tube 104 configured to generate and direct a beam of X-ray radiation 106 toward a subject or object 102 to be imaged. Specifically, in the illustrated embodiment, the X-ray tube 104 is configured to direct the beam of X-ray radiation 106, which passes through the subject 102 toward an X-ray detector 108. In some system configurations, the X-ray tube 104 may direct a collimated fan- or cone-shaped beam of X-ray radiation that is located within an XYZ plane of a Cartesian coordinate system. However, other beam profiles and / or systems are contemplated. Each detector element of the X-ray detector 108 generates an individual electrical signal that is a measure of the X-ray beam attenuation at the detector element location.

[0017] 1, only one X-ray tube 104 and one X-ray detector 108 are shown, in certain embodiments, multiple X-ray tubes and / or multiple X-ray detectors may be used to project and detect multiple beams of X-ray radiation. For example, in a CT application, multiple detectors may be used in conjunction with multiple X-ray tubes to obtain projection data corresponding to a subject at different energy levels.

[0018] The X-ray system 100 may further include an X-ray controller 110 or an X-ray generator configured to provide power and / or timing signals to the X-ray tube 104. The system may also include a data acquisition system that samples analog data received from the X-ray detector elements and converts the analog data to a digital signal for post-processing.

[0019] In certain embodiments, the X-ray system 100 may further include a computing device 112 having a processor 114 that controls system operation based on operator input. The computing device 112 receives operator input including, for example, commands and / or scanning parameters, through an operator console 116 operably coupled to the computing device 112. The operator console 116 may include a keyboard, touch screen, and / or other suitable input devices (not shown) that enable an operator to specify commands and / or scanning parameters.

[0020] 1, multiple operator consoles may be included in the X-ray system 100, e.g., for inputting or outputting system parameters, requesting examinations, plotting data, and / or viewing images. Additionally, in some embodiments, the X-ray system 100 may be coupled to multiple displays, printers, workstations, and / or similar devices, e.g., located locally or remotely and connected, e.g., through a wired and / or wireless network. In one embodiment, the display 120 may be in electronic communication with the computing device 112 and may be configured to display a graphical interface showing system parameters, control settings, imaging data, etc.

[0021] In one example, computing device 112 stores data on storage device 118, which may include, for example, a hard disk drive, a floppy disk drive, a compact disk read / write (CD-R / W) drive, a digital versatile disk (DVD) drive, a flash drive, and / or a solid-state storage drive, or other type of suitable storage device.

[0022] Additionally, the computing device 112 provides commands to the X-ray controller 110 and other system components to control system operations (e.g., forming an X-ray beam, collecting data, and / or processing data). Thus, in certain embodiments, the computing device 112 controls system operations based on operator input. In particular, the computing device 112 can operate the X-ray controller 110 with operator-supplied and / or system-defined commands and parameters, which in turn can control the X-ray tube 104. In this manner, the intensity and timing of X-ray beam generation can be controlled. It is also understood that the rotational speed of the anode target of the X-ray tube can be adjusted by the computing device 112 in cooperation with the X-ray controller 110. The anode target can be a rotating element coupled to a liquid metal bearing assembly.

[0023] Various methods and processes may be stored as executable instructions in a non-transitory memory of a computing device (or controller) of the X-ray system 100. In one embodiment, the X-ray controller 110 may include the executable instructions in a non-transitory memory and perform the methods to control the X-ray tube 104. In another embodiment, the computing device 112 may include the instructions in a non-transitory memory and transmit at least some of the instructions to the X-ray controller 110, which may adjust the X-ray tube power.

[0024] FIG. 2 illustrates a schematic diagram of a vacuum processing assembly 200 used to create a vacuum environment in an X-ray tube insert 202 of an exemplary X-ray tube. The exemplary schematic diagram of FIG. 2 is not drawn to scale and is a general schematic diagram depicting components of a vacuum processing assembly 200 for creating a vacuum environment in an X-ray tube insert 202 of an exemplary X-ray tube. The exemplary vacuum processing assembly 200 further includes a vacuum pump 204 coupled to the X-ray tube insert 202 through one or more portions of a tube assembly. The vacuum pump 204 creates a vacuum environment during the manufacture of the X-ray tube. The first piece of tube or pipe is a vacuum tube 206. Copper is a preferred material for the vacuum tube coupled to the X-ray tube insert 202 because it creates an excellent vacuum environment. However, other suitable materials may be used for the vacuum tube 206 instead of copper. A first end of the vacuum tube 206 may be connected to a first end of an extension tube 208 via an adapter 210. The exemplary vacuum tube 206 includes a second end coupled to the x-ray tube insert 202 through a socket 212. The second end of the extension tube 208 is coupled to the vacuum pump via a fitting 214. In the illustrated embodiment, the extension tube 208 allows the vacuum pump 204 to be located away from the x-ray tube insert 202. For example, manufacturing constraints may require a specific length of tubing or tubing between the x-ray tube insert 202 and the vacuum pump 204. In another embodiment, the second end of the vacuum tube may be directly coupled to the vacuum pump by a fitting. Various lengths of the vacuum tube 206 or extension tube 208 may be used to meet manufacturing requirements. Additionally, the use of the extension tube 208 is advantageous over the use of a long vacuum tube 206 because less copper is wasted during manufacturing. Additionally, the extension tube 208 may be attached to the vacuum tube 206 only during the manufacturing process where a vacuum environment is formed within the x-ray tube insert 202. Thus, the length of tube attached to the x-ray tube insert 202 during the majority of production time is shorter, making it easier to handle.

[0025] The example adapter 210 includes a sleeve portion for attaching the end of the vacuum tube 206 and the end of the extension tube 208 to join. In some embodiments, the diameters of the vacuum tube 206 and the extension tube 208 are different, while in other embodiments, the diameters of the vacuum tube 206 and the extension tube 208 are the same, and thus the adapter provides a rigid connection between the two ends. The example adapter can be coupled to the vacuum tube 206 and the extension tube 208 using any suitable means, such as brazing and / or welding. The example socket 212 can be coupled to the example x-ray tube insert 202 and / or the example vacuum tube 206 using any suitable means, such as brazing and / or welding. The example fitting 214 can be coupled to the extension tube 208 using any suitable means, including welding, and can be coupled to the vacuum pump 204 using, for example, a number of removable fasteners, such as bolts, screws, or other types of fasteners.

[0026] 3A is a partial cross-sectional view of an X-Ray tube insert 202 coupled to a vacuum processing assembly 200 according to one embodiment. In the illustrated embodiment, the X-Ray tube insert 202 includes an anode assembly 306 and a cathode assembly 314. The anode assembly 306 and the cathode assembly 314 are coupled to a support plate or central frame 308 and supported within a housing or casing (not shown). The housing or casing encloses the anode assembly 306, which includes an anode target and bearing assembly (not shown), and the cathode assembly 314. The X-Ray tube insert 202 defines a region of relatively low or no pressure (e.g., vacuum) relative to the surroundings, in which a high voltage is applied. The X-Ray tube insert 202 may be disposed within a casing or housing (not shown) filled with a cooling medium (such as a dielectric oil) that also provides high voltage insulation. Although the anode target and anode assembly have been described as being common components of the X-Ray tube insert 202, in alternative embodiments of the X-Ray tube, the anode target and anode assembly may be separate components. A support plate or central frame 308 supports the anode assembly 306 and the cathode assembly 314. The anode assembly 306 and the cathode assembly 314 may be attached to the support plate 308 by brazing and / or welding.

[0027] In operation, an electron beam is generated by the cathode assembly 314. In particular, the cathode assembly 314 receives one or more electrical signals through a number of electrical cables, leads, or wires. The electrical signals may include power and timing / control signals that cause the cathode assembly 314 to emit an electron beam at one or more energies and one or more frequencies. The electrical signals may also at least partially control the electrical potential between the cathode assembly 314 and the anode assembly 306. In some embodiments, the cathode cup includes a focusing element that focuses electrons emitted from a filament or other electron emitter in the cathode cup to form the electron beam.

[0028] High speed electrons of the electron beam from the emitter of the cathode assembly 314 rapidly decelerate when they strike a target track formed on the surface of the anode target in the anode assembly 306, generating x-rays. The high speed electrons forming the electron beam are accelerated toward the anode target by the potential difference between the electrons and the anode target. The x-rays are emitted through an x-ray emission window 310 formed in the x-ray tube insert 202 and positioned toward the x-ray detector 108 of FIG.

[0029] The anode assembly 306 includes a rotor and stator 312 disposed at one end of the anode assembly 306 for rotating the anode target during operation. The anode target is rotatably supported by a bearing assembly such that rotation of the bearing assembly causes the anode target to rotate about a centerline. The anode target has a generally annular shape, such as a disk, with an annular opening in the center of the anode target that receives the bearing assembly.

[0030] The anode target can be fabricated to include multiple metals or composite materials, such as tungsten, molybdenum, or any material that contributes to bremsstrahlung (i.e., slowing down radiation) when electrons strike the anode target. The target track of the anode target can be selected to have a relatively high degree of refractory properties to withstand the heat generated by the electrons striking the target track. Additionally, the space within the x-ray tube insert 202 between the cathode assembly 314 and the anode assembly 306 is at a vacuum pressure to minimize collisions of the electrons with other atoms and maximize the electrical potential.

[0031] To avoid overheating the anode target when electrons strike it, the rotor rotates the anode target about its centerline at high speeds (e.g., 90 Hz to 250 Hz). In addition to the anode target rotating within the anode assembly of the x-ray tube insert, in CT applications the entire x-ray tube rotates within a gantry (not shown) around the object or subject being imaged, typically at a rate of 1 Hz or faster.

[0032] 3A also illustrates an exemplary vacuum processing assembly 200 for forming a vacuum environment within the x-ray tube insert 202. The exemplary vacuum processing assembly 200 includes a vacuum tube 206, an adapter 210, and an extension tube 208, as described in connection with FIG. 2, except that the exemplary extension tube 208 is coupled to a valve 304 using a valve sleeve 302 or an adapter. The valve 304 is coupled to a vacuum pump 204. The valve 304 can be opened to allow the vacuum pump 204 to form a vacuum environment within the x-ray tube insert 202. The valve 304 can be coupled to the vacuum pump 204 in any suitable manner, including by welding or fasteners.

[0033] 3B illustrates a partial cross-sectional view of an alternative example of an x-ray tube insert 202 coupled to a vacuum processing assembly 200 according to one embodiment. Similar to FIG. 3A, in the illustrated embodiment of FIG. 3B, the x-ray tube insert 202 includes an anode assembly 306 and a cathode assembly 314.

[0034] 3B also illustrates an alternative exemplary vacuum processing assembly 200 for forming a vacuum environment within the x-ray tube insert 202. The exemplary vacuum processing assembly 200 includes the exemplary vacuum tube 206 as described in FIG. 2. However, the exemplary vacuum tube is coupled directly to a valve 304 using a valve sleeve 214 or an adapter, rather than the vacuum tube 206 being coupled to an adapter 210 and an extension tube 208. The valve 304 is coupled to a vacuum pump 204. The valve 304 can be opened to allow the vacuum pump 204 to form a vacuum environment within the x-ray tube insert 202.

[0035] 4 and 5A are more detailed views of an exemplary vacuum processing assembly 200 for forming a vacuum environment within the x-ray tube insert 202, the vacuum processing assembly 200 including an exemplary embodiment of a vacuum tube 206, an extension tube 208, an adapter 210, an exemplary socket 212, and an exemplary fitting 214. FIG. 5B illustrates an alternative exemplary processing assembly 200. The exemplary vacuum processing assembly 200 includes an exemplary vacuum tube 206. However, the exemplary vacuum tube is directly coupled to the valve 304 using a valve sleeve 214 or an adapter, rather than the vacuum tube 206 being coupled to an adapter 210 and an extension tube 208. Other exemplary embodiments may include other or additional components different from those described with respect to the exemplary embodiment of FIG. 4. In the illustrated example, the vacuum tube 206 is shorter than the extension tube 208, but either the vacuum tube 206 or the extension tube 208 may be as long as necessary or desired to fit the constraints of the manufacturing environment.

[0036] In the embodiment shown in Figures 4 and 5A, the vacuum tube 206 is coupled to the support plate or central frame 308 of the X-Ray tube insert 202 via a socket 212. The exemplary socket 212 includes an annular ring into which the second end of the vacuum tube 206 is inserted. The vacuum tube 206 may be brazed to the annular ring. The annular ring extends from a surface of the support plate 308. The socket 212 may further include an annular U-shaped portion that fits into a corresponding annular groove in the support plate 308. The U-shaped portion may be welded to the support plate or may be permanently fixed to the support plate. Other socket configurations may be used as long as the socket connects the vacuum tube to the X-Ray tube insert 202 in a manner that allows a vacuum environment to be created. The exemplary socket 212 is steel (e.g., stainless steel), but other suitable metals may be used instead. Figure 7 shows the end of the socket 212 welded to the support plate 308 from the opposite side of the support plate. If the vacuum environment is breached (e.g., due to damage or wear to the x-ray tube insert) and / or if the x-ray tube insert needs to be repaired, the example vacuum tube 206 can be removed, the socket 212 machined, and the x-ray tube insert 202 can be reused with a new vacuum tube portion and socket.

[0037] The second end of the vacuum tube 206 is brazed to the inner surface of the adapter 210. The exemplary adapter 210 includes a flange portion adjacent the vacuum tube 206. Additionally, an inner annular groove of the adapter is adapted for brazing the vacuum tube to the adapter. The exemplary adapter 210 tapers toward the extension tube 208 to a sleeve portion having an outer diameter equal to the outer diameter of the majority of the extension tube 208. The end of the extension tube 208 has a slightly smaller diameter so that the extension tube 208 fits within the adapter 210. The extension tube 208 is welded to the adapter 210 before the extension tube 208 is inserted into the adapter 210 and the vacuum pump is activated. After the adapter is removed from the vacuum tube (e.g., after the vacuum tube is pinched off), the adapter can be machined to reuse the extension tube, thereby avoiding waste of material. The exemplary adapter is steel (e.g., stainless steel).

[0038] The exemplary fitting 214 is provided at a second end of the extension tube 208. In some cases, the fitting 214 may be integral with the extension tube 208. Alternatively, the fitting 214 may be welded or otherwise secured to the end of the extension tube 208. The exemplary fitting 214 is removably secured to the vacuum pump 204. FIG. 6 illustrates an end of the fitting 214, which includes a fastener 602 that can be used to connect the fitting 214 to the vacuum pump 204. The exemplary fasteners are screws and bolts, although other suitable fasteners (clips, pins, etc.) may be used instead.

[0039] Figure 8A shows an exemplary vacuum tube 206 coupled to a support plate 308 using a socket 212 after the vacuum environment of the X-Ray tube insert 202 has been sealed by pinching or cold pressing the ends of the vacuum tube 206. As shown in Figure 8A, the vacuum tube 206 is pinched off between the socket 212 and the adapter 210. Although the vacuum tube 206 could be pinched off anywhere between the socket 212 and the adapter 210 or the vacuum tube 204, it is desirable to pinch off the vacuum tube 206 closer to the socket to reduce the length of the tube that extends from the X-Ray tube insert 202.

[0040] FIGURE 8B illustrates another example vacuum tube 206 after the end of the vacuum tube 206 has been pinched or cold pressed to seal the vacuum environment of the X-Ray tube insert 202. However, the example vacuum tube 206 shown in FIGURE 8B is not coupled to the support plate using a socket 212, but rather is directly coupled to the support plate 308. As shown in FIGURE 8B, the vacuum tube 206 is pinched off between the socket 212 and the adapter 210. Although the vacuum tube 206 could be pinched off anywhere between the support plate 308 and the adapter 210 or vacuum pump 204, it is desirable to pinch off the vacuum tube 206 closer to the socket in order to shorten the length of the tube that extends from the X-Ray tube insert 202.

[0041] 9 illustrates an example method 900 for forming an example vacuum environment in the x-ray tube insert 202 using example embodiments described herein. The method 900 begins at block 902, where the vacuum tube 206 and socket 212 are connected to the support plate 308. The vacuum tube 206 is connected to the support plate 308 early in the manufacturing process. As described above, the socket 212 is welded to the support plate 308 and the vacuum tube is brazed to the socket 212. At this time, the adapter 210 is also brazed to the vacuum tube 206.

[0042] Next, when creating a vacuum environment, the extension tube 208 is welded to the adapter 210 (block 904). If the adapter 210 is not already coupled to the vacuum tube 206, the adapter 210 is first brazed to the vacuum tube 206. If the fitting 214 is not already assembled to the extension tube 208, the fitting 214 is also welded to the extension tube 208.

[0043] At block 906, the vacuum pump 204 is coupled to the extension tube 208 via the fitting 214. In the example shown in Figures 4-7, the fitting 214 is coupled to the vacuum pump 204 using fasteners 602.

[0044] At block 908, the vacuum pump is activated to create a vacuum environment within the X-Ray tube insert 202. Next, at block 910, the vacuum tube 206 is pinched or cold pressed to seal the vacuum environment within the X-Ray tube insert 202. This concludes the method 900.

[0045] 10 illustrates an example method 1000 of forming an example vacuum environment in an x-ray tube insert 202 using example embodiments described herein. The method 1000 begins at block 1002, where the vacuum tube 206, and in some examples the socket 212, are connected to a support plate 308. The vacuum tube 206 is connected to the support plate 308 early in the manufacturing process. As discussed above, when the vacuum tube 206 is connected to the socket 212, the socket 212 is welded to the support plate 308 and the vacuum tube is brazed to the socket 212.

[0046] At block 1004, the vacuum pump 204 is coupled to the vacuum tube 208 via the fitting 214. In the example shown in Figures 4-7, the fitting 214 is coupled to the vacuum pump 204 using fasteners 602.

[0047] At block 1006, the vacuum pump is activated to create a vacuum environment within the X-Ray tube insert 202. Next, at block 1008, the vacuum tube 206 is pinched or cold pressed to seal the vacuum environment within the X-Ray tube insert 202. This concludes the method 1000.

[0048] A technical effect of using the exemplary system for forming a vacuum in an x-ray tube insert is that material waste is reduced since the extension tube 208 and the socket and x-ray tube 202 are reusable. Additionally, less copper is wasted by using the extension tube instead of a long vacuum tube. Using a short vacuum tube reduces manufacturing concerns and constraints prior to forming the vacuum environment.
