Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an aperture structure of medical equipment, equipment and a radiotherapy system. Background Art

[0002] In the prior art, radiotherapy is often used in conjunction with computed tomography (CT) or magnetic resonance (MR) medical imaging equipment to determine the specific location of lesions and, therefore, their proper position relative to the linear accelerator's radiation. Those skilled in the art will appreciate that CT medical imaging equipment is particularly suited for imaging bones, while MR medical imaging equipment is particularly suited for imaging soft tissue.

[0003] The patient is positioned within the medical imaging device to image the lesion and fine-tune the patient's position. The patient is then transferred to the medical linear accelerator, which delivers radiation to the lesion. However, in existing technologies, both the medical linear accelerator and the medical imaging device occupy a relatively large volume, and the aperture of the main frame of the medical imaging device is a standard circular aperture. Under these conditions, once the bed carrying the patient enters the aperture, the height of the bed's descent is limited by the inner circular boundary of the aperture, resulting in a very limited treatment space. This increases the difficulty of adjusting the patient's position, complicates the treatment process, reduces efficiency, and even compromises treatment effectiveness.

[0049] To further clarify the objectives, advantages, and features of the present invention, the following detailed description of the medical device aperture structure, device, and radiotherapy system proposed by the present invention is provided in conjunction with the accompanying drawings. It should be noted that the drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention. It should be understood that the drawings in this specification do not necessarily depict the specific structures of the present invention to scale, and that illustrative features used to illustrate certain principles of the present invention in the drawings may be slightly simplified. The specific design features of the present invention disclosed herein, including, for example, specific dimensions, orientations, positions, and shapes, will be determined in part by the specific intended application and environment. Furthermore, in the embodiments described below, the same reference numerals may be used across different figures to denote the same parts or parts having the same function, and repeated descriptions thereof may be omitted. Throughout this specification, similar reference numerals and letters are used to denote similar items. Therefore, once a term is defined in one figure, it need not be further discussed in subsequent figures. Where appropriate, these terms are interchangeable.

[0050] To facilitate understanding of the present invention, before specifically introducing the aperture structure of the medical device proposed in the present invention, the relevant principles of the present invention proposed by the inventor are briefly explained as follows:

[0051] See also Figure 1 and Figure 2 ,in, Figure 1 is a schematic structural diagram of one of the radiotherapy systems in the prior art; Figure 2 FIG. 1 is a structural diagram of another radiotherapy system in the prior art. Figure 1 and Figure 2 It can be seen that the radiotherapy system includes a radiotherapy device 110 , a medical imaging device 120 and a patient bed 130 .

[0052] The radiotherapy device 110 includes a housing 115 and a drum 111 disposed within the housing 115. The drum 111 defines a horizontally extending through-hole 112. A treatment arm 113 is secured to the drum 111 at one end and extends outward at the other end. A treatment head 114 is secured to the other end of the treatment arm 113. The drum 111 is also provided with an electronic portal imaging device 116. The electronic portal imaging device 116 and the treatment head 114 are located at the same end of the drum 111 and are symmetrically arranged about the through-hole 112. In other embodiments, the treatment head 114 can be attached directly to the drum 111 without the treatment arm 113, thereby forming a ring-shaped radiotherapy device.

[0053] The medical imaging device 120 includes a housing 125 and a drum 121 disposed within the housing 125. The drum 121 defines a through hole 122 extending horizontally. A X-ray tube 123 and a detector 124 are disposed within the drum 121 relative to each other. The drum 121 can be understood as a rotatable component used to wrap and / or support, and drive the rotation of, the imaging components of the medical imaging device 120; the housing 125 can be understood as a supporting component used to support the entirety of the medical imaging device 120. The through hole 122 of the medical imaging device 120 can rotate as a whole with the drum 121. Optionally, the medical imaging device 120 can be a CT device, an MR device, a PET device, etc.

[0054] The hospital bed 130 includes a bed board 131 and a bed board support assembly 132. The bed board support assembly 132 is used to support the bed board 131 and can adjust the bed board 131 to translate, lift or rotate in the horizontal and vertical directions in a manner well known in the prior art, so that the bed board 131 can enter and exit the through hole 112 and / or the through hole 122, or adjust the position of the bed board 131 in the through hole 112 and / or the through hole 122.

[0055] Specifically, when imaging a patient, the patient lies on a bed plate 131, which is then moved through through-holes 112 and 122 to position the patient between the X-ray tube 123 and the detector 124. The X-ray tube 113 and the detector 114 then operate in a manner well known in the art to capture images of the patient. When treating the patient, the bed plate 131 is moved so that the target area, as determined by the captured images, is within the beam output range of the treatment head 114. The electronic portal imaging device 116 is configured to receive the beam output from the treatment head 114.

[0056] See Figure 3 and Figure 4 ,from Figure 3 and Figure 4 As can be seen, the apertures of the drum 111 of conventional radiotherapy equipment and the drum 121 of medical imaging equipment are standard circular apertures. When the bed 131 carrying the patient enters the aperture, the height of the bed 131's descent is limited by the inner circular boundary of the aperture, resulting in a restricted vertical range of motion for the bed 131. This problem has long troubled those skilled in the art, and an effective solution has remained elusive.

[0057] Therefore, the core concept of the present invention is to reduce the difficulty of adjusting the patient's position during imaging or treatment, thereby improving treatment efficiency. After extensive in-depth research and continuous practice, the inventors of the present invention discovered that, taking medical imaging equipment 120 as an example, if the diameter of through-hole 122 and the outer diameter of drum 121 were simultaneously increased, not only would the changes be significant, but the positional relationship of the various imaging components (such as X-ray tube 123 and detector 124) located within drum 121 would also need to be adjusted simultaneously, resulting in a significant overall change. Furthermore, medical imaging equipment 120 is inherently large, especially in height. Increasing the outer diameter of drum 121 would also require increasing the overall height of medical imaging equipment 120. This would not only require increasing the size of housing 125, resulting in inefficient costs, but would also impose new requirements on the height of the imaging room, potentially requiring the reconstruction of the examination room housing medical imaging equipment 120. Clearly, this would be prohibitively expensive. While theoretically feasible, simply increasing the diameter of through-hole 122 while maintaining the outer diameter of drum 121 unchanged—that is, reducing the radial thickness of drum 121—would present practical problems. If drum 121 is insufficiently thick, it would lack rigidity and be unable to support the various imaging components housed therein (e.g., X-ray tube 123, detector 124, etc.). This also poses certain risks to the safety and reliability of drum 121 during its rotation. Based on the foregoing investigation, it is not difficult to ascertain that radiotherapy equipment also faces the same problem.

[0058] Despite this, with long-term commitment to relevant research and practice in this field, after continuous attempts and repeated demonstrations, the inventors of the present invention finally creatively proposed a medical equipment aperture structure to increase the lowering height of the bed in the through-hole of the drum, reduce the difficulty of adjusting the patient's position during imaging or treatment, especially the lowering height in the vertical direction, and improve treatment efficiency.

[0059] Based on the above research, this embodiment provides a medical device aperture structure. The medical device aperture structure is used for medical imaging equipment or radiotherapy equipment. For the convenience of description, the following is an example of radiotherapy equipment. Figures 5 to 12 ,in, Figure 5 This is a schematic structural diagram of a radiotherapy device with a medical device aperture structure provided by another embodiment of the present invention (when the drum is rotated 90 degrees clockwise). Figure 6 for Figure 5 The main schematic diagram of Figure 7 、 9 1 and 11 are schematic elevational views of a drum 121 of a radiotherapy device with a medical identification aperture structure according to one embodiment of the present invention, rotated 0°, 90°, and 270° in a clockwise direction, respectively. Figure 8 、 Figure 10 and Figure 12They are Figure 7 、 9 、11 main view. Figure 5-Figure 12 As can be seen from any of the figures, the radiotherapy device includes a rotatable roller 111, and the roller 111 includes the medical device aperture structure 101. The medical device aperture structure 101 includes a through hole 112, and the through hole 112 is configured so that the bed board 131 of the bed 130 can enter and exit the through hole 112 along the axial direction of the through hole 112. The medical device aperture structure also includes at least one escape space 1011 connected to the through hole 112, and the escape space 1011 is provided on the inner wall of the medical device aperture structure 101. Along the axial direction of the through hole 112, the escape space 1011 passes through the medical device aperture structure 101 for entering and exiting one end of the bed board 131, and extends a escape length toward the other end of the medical device aperture structure 101, and the escape length is less than or equal to the length of the through hole. Along the circumferential direction of the medical equipment aperture structure 101 , the width of the escape space 1011 at the opening is greater than the width of the bed plate 130 ; along the radial direction of the medical equipment aperture structure 101 , the escape space 1011 has an escape depth.

[0060] As those skilled in the art can understand, when using the avoidance space 1011 of the medical equipment aperture structure 101 provided by the present invention to increase the descending height of the bed board 131, preferably, the processor module of the medical imaging device 110 should control the main body bracket to drive the medical equipment aperture structure 101 to rotate until the avoidance space 1011 is located at the bottom of the main body bracket, and then control the descending height of the bed board 131, so that the avoidance space 1011 avoids the bed board 131 in the vertical direction, thereby increasing the vertical movement range of the bed 130. Furthermore, although the present invention does not limit the setting position of the avoidance space 1011, it should preferably be set at a position on the main support near the through hole 112 where the treatment head 114 and the electronic portal imaging device 116 are not set. For example, the avoidance space 1011 is set at a position orthogonal to the line connecting the treatment head 114 and the electronic portal imaging device 116, so as to avoid interference with the treatment head 114 or the electronic portal imaging device 116 during the moving process of the bed board 131; further, the present invention does not limit the avoidance length, the width of the opening, and the avoidance depth, and their values ​​should be reasonably set according to actual conditions.

[0061] Preferably, the avoidance space 1011 is used to avoid the bed board 131 in the vertical direction. Figure 13 , Figure 13 Schematic diagram comparing the bedplate lowering height of a radiotherapy device provided by an aperture structure of medical equipment according to one embodiment of the present invention and an aperture structure of medical equipment in the prior art. Figure 13In the embodiment, S1 is the maximum height to which the bed plate 131 can be lowered in the prior art, and S2 is the maximum height to which the bed plate 131 of the medical device aperture structure 101 provided in this embodiment can be lowered. Figure 13 It can be seen that the medical equipment aperture structure 101 provided by the present invention can increase the lowering space of the bed board 131 of the entire bed 130 within the medical equipment aperture structure 101 by setting the avoidance space 1011, thereby reducing the difficulty of adjusting the patient position during imaging or treatment, thereby improving the imaging or treatment efficiency; further, the medical equipment aperture structure 101 provided by the present invention does not require any changes to other components of the existing medical imaging equipment 120, radiotherapy equipment 110 or main support, and is easy to implement; further, the medical equipment aperture structure 101 provided by the present invention does not increase the overall volume of the existing medical imaging equipment 120, radiotherapy equipment 110 or main support, and occupies less medical space resources and has low cost.

[0062] Preferably, in one exemplary embodiment, please continue to refer to Figure 5-Figure 6 ,from Figure 5-Figure 6 As can be seen in any of the figures, the medical device aperture structure 101 provided in this embodiment has two escape spaces 1011, symmetrically arranged about the axis of the through hole 112. The cross-section of the accommodation space formed by the through hole 112 and the escape spaces 1011 is polygonal. Thus, the medical device aperture structure 101 provided by the present invention not only increases the height of the bed plate 131 when lowered, but also facilitates fabrication and maintains the balance and safety of the main frame during rotation.

[0063] Preferably, in another exemplary embodiment, the medical device aperture structure 101 provided in this embodiment has one escape space 1011, the through hole 112 has a circular cross-section, the escape space 1011 has a rectangular cross-section, and the width of the escape space along the circumferential direction of the through hole 112 is greater than the width of the bed plate 131. Thus, the medical device aperture structure 101 provided by the present invention can be easily modified based on existing medical device aperture structures and is easy to implement.

[0064] It should be noted that the above is only a description of a preferred embodiment, and not a limitation of the present invention. Figure 5 and Figure 6 As shown, in some embodiments, the cross section of the accommodation space formed by the through hole 112 and the avoidance space 1101 of the aperture structure 101 of the medical device provided by the present invention is a regular polygonal structure. Figure 10-12In some other embodiments, the cross section of the aperture structure 101 of the medical device provided by the present invention is another polygonal structure: that is, the through hole 112 is a regular polygonal structure, and the cross section of the avoidance space 1101 is a rectangular structure that protrudes outward relative to the cross section of the through hole 112 (that is, it is groove-shaped relative to the interior of the roller 111). For example Figure 13 As shown, in other embodiments, the cross-section of the through hole 112 is circular (as shown by the dotted line in the figure), and the cross-section of the avoidance space 1101 is a rectangular structure: that is, except for the avoidance space, the inner wall of the through hole 112 is arc-shaped. As such, we will not explain them one by one. In short, the present invention does not limit the specific shapes of the through hole 112 and the avoidance space 1101. Preferably, the through hole 112 is preferably polygonal and circular as preferred embodiments; when the through hole 112 is polygonal, a regular polygon is the best, which is closer to a circle, thereby maximizing the use of the annular space between the outer and inner walls of the drum 111, so that the drum 111 can provide more space for arranging the components of the medical device, while reducing the risk of collision between the bed board 131 and the inner wall of the medical device aperture structure 101 when the drum 111 rotates, thereby improving the comfort of the patient. Furthermore, the present invention does not limit the specific shape of the avoidance space 1011. In some other embodiments, its bottom can also be grooved or arc-shaped. Furthermore, the present invention does not limit the number of the avoidance spaces 1011, which may be 1, 2, 3 or more, and will not be described in detail one by one.

[0065] Preferably, in one exemplary embodiment, please continue to refer to Figure 7-12 The medical device aperture structure 101 further includes a control unit (not shown) and adjustable units corresponding one-to-one with the avoidance spaces 1011. The control unit is configured to control the adjustable units to cover the opening of the avoidance spaces 1011 or to keep the adjustable units within the avoidance spaces 1011 based on received control instructions; when the adjustable units remain within the avoidance spaces 1011, the minimum distance between the opening of the avoidance spaces 1011 and the adjustable units is greater than 0.

[0066] Figure 7-12 In the figure, A shows the state of the adjustable unit covering, and B shows the state of the adjustable unit avoiding; Figure 5-12It is not difficult to see that when the vertical movement range of the bed board 131 needs to be increased (especially the lowering height), the adjustable unit can be controlled to cover the opening of the escape space 1011; when the vertical movement range of the bed board 131 does not need to be increased (especially the lowering height), the adjustable unit can be controlled to remain in the escape space 1011. Therefore, the medical device aperture structure 101 provided by the present invention controls the adjustable unit to cover the opening of the escape space 1011 or to remain in the escape space 1011 through the control unit, thereby increasing the movement space of the bed board 131 of the entire bed 130, reducing the difficulty of adjusting the patient's position during imaging or treatment, thereby improving treatment efficiency, and maintaining the balance and safety of the existing roller 111.

[0067] It should be noted that the present invention does not impose any restrictions on the form of the control unit. In one embodiment, the control unit can be a standalone module capable of communicating with the processor module of the medical imaging device 110 or the radiotherapy device 120, or it can be integrated into the processor module so as to control the position of the adjustable unit when the processor module detects the need to cover or open the avoidance space 1011. Furthermore, the present invention does not limit the connection method between the control unit and the adjustable unit 1012. In one embodiment, it is a wired connection, and in another embodiment, it is a wireless connection, preferably a wireless connection.

[0068] Preferably, in one exemplary embodiment, please continue to refer to Figure 7-12 ,from Figures 7 to 12 It can be seen that the adjustable unit is a cover plate 1012; the cross-section of the avoidance space 1011 is a rectangle; along the circumferential direction of the through hole 112, the width of the cover plate 1012 is adapted to the inner wall of the avoidance space 1011; along the axial direction of the through hole 112, the length of the cover plate 1012 is adapted to the length of the avoidance space 1011.

[0069] In one exemplary embodiment, the cover plate 1012 is an arc surface. In the closed state, the cover plate 1012 and the inner wall of the through hole 112 form a circular through hole.

[0070] Preferably, in one embodiment, the cover plate 1012 can be made of an elastic material, which can change its shape and rigidity under the action of external force (tension, compression); in another embodiment, it can also be made of a non-elastic material, which can move its position under the action of external force. Preferably, in this case, the cross-section of the avoidance space 1012 along the radial direction of the through hole 112 is rectangular.

[0071] The adjustable unit of the aperture structure 101 of the medical device provided by the present invention is a cover plate 1012 , thereby, while maintaining the balance and safety of the existing main support, the cover plate 1012 is easy to process.

[0072] Preferably, in one exemplary embodiment, a connector (damping avoidance support assembly) 1013 is further included, and the connector 1013 connects the cover plate 1012 and the inner wall of the avoidance space 1011. With such a configuration, the medical device aperture structure provided by the present invention, in which the cover plate 1012 is fixed to the inner wall of the avoidance space 1011 by the connector 1013, can prevent the cover plate 1012 from unexpectedly moving or falling during the rotation of the roller 121, thereby maximizing the safety of the patient. Furthermore, it should be noted that the present invention does not limit the specific form of the connector 1013. In one embodiment, the connector 1013 can be a telescopic rod, that is, when the cover plate 1012 is in the covering state, the control unit controls the connector 1013 to be in the extended state; when the cover plate 1012 is in the avoidance state, the control unit controls the connector 1013 to be in the compressed state. In other embodiments, the connector 1013 may be a foldable component, such as a double scissor-shaped component. When the cover 1012 is in the closed state, the control unit controls the connector 1013 to be in the retracted state; when the cover 1012 is in the evasive state, the control unit controls the connector 1013 to be in the open state. Details are omitted here. It should be noted that the medical device aperture structure 101 provided by the present invention is not limited to the number of connectors 1013, and may be one, two, or more. In specific applications, a reasonable selection should be made based on actual conditions.

[0073] In another embodiment, the adjustable unit of the aperture structure 101 of the medical device provided herein is a gas bag having a certain rigidity, and the control unit is an inflation / suction device, such as a suction / inflation pump. The inflation / suction device can be connected to and controlled by a processor module of the medical imaging device 110 or radiotherapy device 120. The inflation / suction device is configured to fill the gas bag with gas so that the gas bag can fill the avoidance space 1011, or to extract gas from the gas bag so that the gas bag can conform to the inner wall of the avoidance space.

[0074] Correspondingly, when the inflatable bag is filled with gas, it can fill the avoidance space 1011, and its side facing the through hole 112 is adapted to the opening of the avoidance space 1011; when the gas in the inflatable bag is evacuated, the airbag remains in the avoidance space 1011, so that the through hole 112 can enter and exit the through hole 112 through the avoidance space 1011.

[0075] As those skilled in the art will appreciate, the above description is merely an exemplary description and not a limitation of the present invention. The present invention does not limit the specific form of the adjustable unit and the manner in which it is connected to the control unit.

[0076] Based on the same inventive concept, another embodiment of the present invention further provides a medical device, comprising the medical device aperture structure described in any of the aforementioned embodiments. As will be appreciated by those skilled in the art, the medical device provided in this embodiment includes, but is not limited to, a medical imaging device and a radiotherapy device. The medical imaging device includes, but is not limited to, a medical imaging device, an MR imaging device, or a PET imaging device.

[0077] Based on the same inventive concept, another embodiment of the present invention also provides a medical device, which includes a through hole extending in a horizontal direction, and the cross-section of the through hole is non-circular; the through hole is configured so that the bed board of the hospital bed can move in and out of it along the axial direction of the through hole, and so that the movement range of the bed board along the first direction therein is greater than the movement range along the second direction; wherein the angle between the first direction and the second direction is greater than 0°, and the first direction and the second direction are both perpendicular to the axial direction of the through hole.

[0078] Preferably, in one embodiment, the through hole has a polygonal cross-section. Furthermore, the first direction is a vertical direction; furthermore, the distance between the centerline of the through hole and the upper inner wall of the through hole is less than the distance between the centerline and the lower inner wall of the through hole. With this configuration, the medical device provided by the present invention, by designing the through hole to have a non-circular cross-section and enabling the bed board to move in and out of the through hole along the axis of the through hole, can increase the movement space of the entire bed board, reduce the difficulty of adjusting the patient's position during imaging or treatment, thereby improving treatment efficiency, and reduce the difficulty of machining the through hole.

[0079] Based on the same inventive concept, another embodiment of the present invention provides a radiotherapy system comprising a medical imaging device and a radiotherapy device, wherein at least one of the medical imaging device and / or the radiotherapy device comprises any of the aforementioned medical device aperture structures. Thus, by combining the treatment head of the radiotherapy device and the magnetic resonance imaging device, the medical imaging device can simultaneously capture images while the radiotherapy device is performing radiotherapy. In some embodiments, the radiotherapy device and the medical imaging device can be used independently, sequentially, or simultaneously.

[0080] Preferably, in one exemplary embodiment, the through holes of the radiotherapy equipment 110 and the medical imaging equipment 120 are connected, and the radiotherapy equipment 110 is arranged near the hospital bed 130; the radiotherapy equipment 110 includes the medical equipment aperture structure 101, and the avoidance space 1011 of the medical equipment aperture structure 101 of the radiotherapy equipment 110 is configured to accommodate the bed board support assembly 132 of the hospital bed 130 to enter the through hole 112 a preset distance, so that the bed board support assembly 132 can enter and exit the through hole 112 along the axial direction of the through hole 112.

[0081] With this configuration, the radiotherapy system provided by the present invention only requires the escape space to be provided within the through-hole 112 of the radiotherapy device 110, while the through-hole of the medical imaging device 120 (such as a CT scanner) can retain its conventional annular shape. This reserves space for the support assembly 132 of the bed 131, allowing the support assembly 132 to partially extend into the escape space 1011, eliminating the need to raise the bed 131 for imaging and scanning. This not only improves imaging and treatment efficiency but also reduces the length of the bed, preventing excessive sinking caused by an excessively long bed. This reduces the overall weight and space occupied by the radiotherapy system, conserving resources.

[0082] As can be understood by those skilled in the art, the radiotherapy system provided by the present invention does not limit the positions and connection relationship between the radiotherapy device 110 and the medical imaging device 120: in one exemplary embodiment, the radiotherapy device 110 and the medical imaging device 120 of the radiotherapy system can be integrally formed, such as Figure 1 In another exemplary embodiment, the radiotherapy device 110 and the medical imaging device 120 of the radiotherapy system may also be separate, such as being located in the same treatment space (such as a treatment room) and sharing the same bed 130, such as Figure 2 The positional relationship shown; in another embodiment, the radiotherapy equipment 110 and the medical imaging equipment 120 of the radiotherapy system are located in different treatment spaces, and the radiotherapy equipment 110 and the medical imaging equipment 120 each have an independent bed 130, for example, the medical imaging equipment is located in the shooting room; the radiotherapy equipment is located in the treatment room.

[0083] Furthermore, the radiotherapy system provided by the present invention may also include a processor module (not shown in the figure), which can process data and / or information obtained from the medical imaging device 120, the radiotherapy device 110, and / or the patient bed 130. For example, the processor module can control the treatment parameters of the radiotherapy device 110 based on the image data collected by the medical imaging device 120, where the treatment parameters may include but are not limited to the radiation dose, the rotation angle of the treatment head, etc.; for another example, the processor module can obtain user instructions from a terminal (not shown in the figure, which can be an output device including but not limited to a display, keyboard, mouse, etc.).

[0084] The processor module can also send control instructions to one or more components of the system (e.g., the radiotherapy device 110, the medical imaging device 120, and the hospital bed 130). For example, the processor module can send control instructions to the medical imaging device 120 to move the active components of the medical imaging device 120 (e.g., the ionization chamber, detector, roller, etc.) to a specified position. In another example, the processor module can send control instructions to a terminal to cause the terminal to display image data on its display interface. In another example, the processor module can rotate the roller so that the avoidance space 1011 of the medical device aperture structure 1011 of the radiotherapy device 110 is located at the bottom, and accordingly control the hospital bed 130 to move downward a preset distance.

[0085] In some embodiments, the processor module can be a single server or a server group. The server group can be centralized or distributed. In some embodiments, the processor module can be local or remote to the radiotherapy system. For example, the processor module can access information and / or data from the radiotherapy device 110, the medical imaging device 120, and the hospital bed 130 via a network. For another example, the processor module can be directly connected to the radiotherapy device 110, the medical imaging device 120, and the hospital bed 130 to access information and / or data. In some embodiments, the processor module can be implemented on a cloud platform. For example, the cloud platform can include a private cloud, a public cloud, a hybrid cloud, a community cloud, a distributed cloud, an inter-cloud, a multi-cloud, etc., or a combination thereof.

[0086] In some embodiments, the processor module may include one or more processors (e.g., a single-chip processor or a multi-chip processor). By way of example only, the processor module may include a central processing unit (CPU), an application-specific integrated circuit (ASIC), an application-specific instruction set processor (ASIP), a graphics processing unit (GPU), a physical processing unit (PPU), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic device (PLD), a controller, a microcontroller unit, a reduced instruction set computer (RISC), a microprocessor, etc., or any combination thereof.
