Description

Technical Field

[0001] The utility model relates to the technical field of X-ray imaging, in particular to an X-ray photography system and a detection bed and bed board component thereof. Background Art

[0002] Most patient beds in current X-ray imaging systems are not completely flat. The bed beam structure is higher than the upper surface of the bed board, which leads to the following problems: 1. There is a certain height difference between the bed beam and the bed surface, which affects the patient's movement; 2. There is an assembly gap or step surface between the bed beam and the bed board, which easily accumulates dust and is difficult to clean the bed surface;

[0003] Most existing fully flat beds are constructed by directly stacking the bed panels and bed beams to avoid secondary processing of the already formed complete bed panels. The thickness of the bed panel assembly in this structure is relatively large, resulting in a large distance between the upper surface of the bed and the flat-panel detector under the bed panel, affecting the imaging quality; directly reducing the thickness of the bed panel assembly will affect its structural strength.

[0054] The present invention is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted under different circumstances, or may be replaced by other elements, materials, or methods.

[0055] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0056] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0057] In one embodiment, a testing couch for an X-ray imaging system is provided. The couch is used to carry an object to be examined (e.g., a patient) for X-ray imaging to obtain test images for lesion diagnosis. The top surface of the couch's bed plate assembly is completely flat, without a raised border, making it easier for the subject to move across the bed. The flat bed plate assembly also offers a more aesthetically pleasing appearance. Furthermore, the couch's bed plate assembly is both ultra-thin and structurally strong. Reducing the thickness of the bed plate assembly shortens the distance between the subject to be examined and the flat-panel detector, thereby improving imaging quality.

[0058] Please refer to Figures 1 to 7 The X-ray imaging system inspection bed of this embodiment primarily comprises a bedplate assembly 10 and a base 20. The base 20 can be fixed to the ground, and the bottom of the base 20 can also be provided with a movable structure such as a roller, allowing the base 20 to be moved to different locations. The bedplate assembly 10 is mounted on the top of the base 20, providing support for the bedplate assembly 10.

[0059] The base 20 may include a lifting assembly, to which the bed deck assembly 10 is connected. The lifting assembly can drive the bed deck assembly 10 up and down to adjust the bed deck assembly 10 to a suitable height, making it easier for the subject to get in and out of bed. Of course, the base 20 can also be a fixed structure, with the bed deck assembly 10 installed at a fixed height, which can adapt to most usage scenarios.

[0060] A mounting bracket 201 is provided at the upper end of the base 20, and the mounting bracket 201 is located directly below the bed board assembly 10. The mounting bracket 201 is used for detachably mounting a flat-panel detector. The flat-panel detector mounted on the mounting bracket 201 is used to collect and receive X-rays that pass through the object to be inspected and the bed board assembly 10 to obtain detection data, which is used to form a detection image.

[0061] In this embodiment, the bed board assembly 10 includes a bed panel 1 and a support member 2. The bed panel 1 and the support member 2 are stacked one above the other, with the bed panel 1 positioned above the support member 2. The bed panel 1 is a square plate, and the support member 2 is a frame structure. The support member 2 is supported on all four sides of the lower surface of the bed panel 1 near the edge. The support member 2 can be made of a relatively hard metal material, such as an aluminum alloy.

[0062] The square bed panel 1 has a length direction and a width direction. The length direction is the left and right direction of the bed panel 1, and the width direction is the front and back direction of the bed panel 1. That is, the length of the bed panel 1 in the front and back direction is smaller than the length in the left and right direction.

[0063] The bed panel 1 has an upper surface and a lower surface. The upper surface of the bed panel 1 is completely flat and is used to support the object being inspected. The lower surface of the bed panel 1 includes a transmissive surface 11 and a mounting surface 12. Transmissive surface 11 occupies the majority of the lower surface area and is located in the center. Mounting surface 12 is an annular surface that surrounds transmissive surface 11. Transmissive surface 11 corresponds to the foam board inside the bed panel 1. The foam board can be made of a foam material such as PM1 foam or polyurethane foam. Transmissive surface 11 and the corresponding upper surface area directly above it are used to transmit X-rays. Mounting surface 12 corresponds to the support structure, such as the support plate, inside the bed panel 1 and is connected to the support member 2.

[0064] The mounting surface 12 may include multiple mounting surfaces, at least two of which have a height difference. In this embodiment, the mounting surface 12 is a stepped structure, and the mounting surface 12 includes a first mounting surface 121 and a second mounting surface 122 with a height difference, and includes a first mounting surface 121 and a second mounting surface 122.

[0065] In this embodiment, the inward and outward directions of the mounting surface 12 and the transmission surface 11 are parallel to each other as the first direction, and the first direction is parallel to the left and right direction and the front and back direction of the bed panel 1, that is, the first direction of the mounting surface 12 in the length direction of the bed panel 1 is parallel to the front and back direction, and the first direction of the mounting surface 12 in the width direction of the bed panel 1 is parallel to the left and right direction; the direction of the mounting surface 12 around the transmission surface 11 is the second direction, and the second direction is perpendicular to the left and right direction and the front and back direction of the bed panel 1, that is, the second direction of the mounting surface 12 in the length direction of the bed panel 1 is perpendicular to the front and back direction, and the second direction of the mounting surface 12 in the width direction of the bed panel 1 is perpendicular to the left and right direction.

[0066] The first mounting surface 121 and the second mounting surface 122 are arranged along a first direction. Specifically, the first mounting surface 121 and the second mounting surface 122 are two parallel U-shaped surfaces, with the first mounting surface 121 located inward of the second mounting surface 122. The thickness between the first mounting surface 121 and the upper surface of the bed panel 1 is greater than the thickness between the second mounting surface 122 and the upper surface of the bed panel 1. Specifically, the first mounting surface 121 is lower in height than the second mounting surface 122.

[0067] The support member 2 is a frame structure. The support member 2 may include two horizontal beams and two longitudinal beams. The two horizontal beams and the two longitudinal beams are interconnected to form a square frame structure. The horizontal beams and the longitudinal beams may be fixed by screw connection, welding, etc. The support member 2 may also be an integrated structure.

[0068] The support member 2 has an upper surface and a lower surface. The upper surface of the support member 2 includes a support surface 21. All or part of the upper surface of the support member 2 is the support surface 21. The support surface 21 is aligned and connected to the mounting surface 12 up and down. The lower surface of the support member 2 is the mounting surface. The lower surface of the support member 2 is connected to the base 20.

[0069] The support surface 21 of the support member 2 is arranged corresponding to the mounting surface 12 of the bed panel 1. The support surface 21 of the support member 2 may include multiple support surfaces. The support surface 21 of the support member 2 is a stepped structure. The stepped structure of the support surface 21 is staggered and complementary to the stepped structure of the mounting surface 12. The protruding part of the mounting surface 12 is connected to the concave part of the support surface 21, and the concave part of the mounting surface 12 is connected to the convex part of the support surface 21.

[0070] In this embodiment, the support surface 21 of the support member 2 includes a first support surface 211 and a second support surface 212 with a height difference. The first support surface 211 and the second support surface 212 are arranged side by side inward and outward along the first direction. The first support surface 211 is located on the inner side of the second support surface 212. The first support surface 211 and the second support surface 212 are U-shaped surfaces. In the height direction, the first support surface 211 is lower than the second support surface 212. The height difference between the first support surface 211 and the second support surface 212 is equal to the height difference between the first mounting surface 121 and the second mounting surface 122. The first support surface 211 is in contact with the first mounting surface 121 and is located directly below the first mounting surface 121. The second support surface 212 is in contact with the second mounting surface 122 and is located directly below the second mounting surface 122.

[0071] In this embodiment, the bed panel 1 and the support member 2 can be fixedly connected by a fixing connector 3 such as a screw. The fixing connector 3 can pass through the support member 2 to connect to the bed panel 1. The fixing connector 3 does not pass through the bed panel 1, so that the upper surface of the bed panel 1 can remain flat and beautiful. The fixing connector 3 is arranged to pass through the first support surface 211 and the first mounting surface 121, that is, the fixing connector 3 is connected to the area of ​​the bed panel 1 with a larger thickness, which can improve the stability of the connection of the fixing connector 3. Among them, there are multiple fixing connectors 3, and the multiple fixing connectors 3 are distributed in sequence along the second direction, that is, the multiple fixing connectors 3 are distributed along the first support surface 211. Of course, the fixing connector 3 can also be arranged to pass through the second support surface 212 and the second mounting surface 122, which can also achieve a fixed connection between the bed panel 1 and the support member 2.

[0072] In other embodiments, the bed panel 1 and the support member 2 can also be fixedly connected by bonding or other means. By applying glue between the first support surface 211 and the first support surface 211, and between the second support surface 212 and the second support surface 212, the bed panel 1 and the support member 2 can also be fixedly connected.

[0073] In this embodiment, please refer to Figure 6 The dividing line between the first mounting surface 121 and the transmission surface 11 is a dotted line, which may not exist in the actual object. The first mounting surface 121 and the transmission surface 11 are located in the same plane, that is, the first mounting surface 121 and the transmission surface 11 are at the same height, so that the lower surface of the bed panel 1 is relatively flatter, which can reduce the processing steps and facilitate installation.

[0074] In other embodiments, the first mounting surface 121 and the transmission surface 11 may also be located in different planes, that is, the first mounting surface 121 and the transmission surface 11 have a height difference, especially the transmission surface 11 is higher than the first mounting surface 121, that is, reducing the thickness of the area corresponding to the transmission surface 11 can reduce the thickness of the transmission area of ​​the bed panel 1 and improve the imaging quality.

[0075] In this embodiment, the bed panel 1 has a first outer side surface surrounding the bed panel 1, and the first outer side surface is perpendicular to the mounting surface 12. The support member 2 has a second outer side surface surrounding the support member 2, and the second outer side surface is perpendicular to the support surface 21. The second outer side surface of the support member 2 can be flush with the first outer side surface of the bed panel 1, or the second outer side surface of the support member 2 can be recessed into the first outer side surface of the bed panel 1, so that the second outer side surface of the support member 2 does not protrude from the first outer side surface of the bed panel 1, which can improve the aesthetics.

[0076] The detection bed of this embodiment has a first mounting surface 121 and a second mounting surface 122 with a height difference on the mounting surface 12 of the bed panel 1, and a first supporting surface 211 and a second supporting surface 212 with a corresponding height difference, so that after the bed panel 1 is stacked and installed on the support member 2, the local height of the support member 2 can be increased without increasing the thickness of the bed board assembly 10; in other words, the bed board assembly 10 can increase the local thickness of the support member 2 while ensuring a relatively thin overall thickness, thereby improving the structural strength of the support member 2, thereby achieving the advantages of both ultra-thinness and sufficient structural strength. Reducing the thickness of the bed board assembly 10 can shorten the distance between the object to be detected and the flat-panel detector, which is beneficial to improving the imaging quality; and the bed panel 1 and the support member 2 are fixed in a stacked manner, so that the upper surface of the bed panel 1 can be fully flat, which is convenient for the object to be detected to pass through the bed and improves the aesthetics.

[0077] The mounting surface 12 and the supporting surface 21 are staggered and complementary stepped structures, which can also play a limiting role in the front-to-back direction and the left-to-right direction, thereby improving the stability of the connection between the bed panel and the support member 2.

[0078] In one embodiment, the positions of the first mounting surface 121 and the second mounting surface 122 are interchangeable, with the outer side of the mounting surface 12 in the first direction protruding from the inner side. Correspondingly, the positions of the first support surface 211 and the second support surface 212 are also interchangeable, with the inner side of the support surface 21 in the first direction protruding from the outer side. This arrangement can also improve the structural strength of the support member 2 and form a stepped plane limit.

[0079] Please refer to Figures 8 to 10In one embodiment, the mounting surface 12 can include more mounting surfaces, for example, the mounting surface 12 also includes a third mounting surface 123, and the first mounting surface 121, the second mounting surface 122, and the third mounting surface 123 have different heights, for example, the three surfaces are arranged in a stepped manner. Correspondingly, the support surface 21 of the support member 2 can include more supporting surfaces, for example, the support surface 21 also includes a third supporting surface 213, the first supporting surface 211, the second supporting surface 212, and the third supporting surface 213, and the third mounting surface 123 is in contact with and connected to the third supporting surface 213. The mounting surfaces 12 and support surfaces 21 arranged in this manner can also ensure that the structural strength of the support member 2 is improved even when the thickness of the bed panel 1 is relatively thin.

[0080] In one embodiment, the multiple mounting surfaces of the mounting surface 12 and the multiple supporting surfaces of the supporting surface 21 may also be stepped surfaces that are not arranged in ascending order. For example, the first mounting surface 121, the second mounting surface 122, and the third mounting surface 123 are arranged in sequence along the first direction, with the second mounting surface 122 protruding from the third mounting surface 123, and the third mounting surface 123 protruding from the first mounting surface 121. Correspondingly, the first supporting surface 211, the second supporting surface 212, and the third supporting surface 213 are arranged in sequence along the first direction, with the second supporting surface 212 recessed within the first supporting surface 211, and the third supporting surface 213 recessed within the third supporting surface 213. Such an arrangement can also improve the structural strength of the support member 2 and form a stepped plane limit.

[0081] Please refer to Figure 11 In one embodiment, at least one of the first mounting surface 121 and the second mounting surface 122 includes a plurality of, and one or more first mounting surfaces 121 and one or more second mounting surfaces 122 can be staggered along the first direction; correspondingly, at least one of the first supporting surface 211 and the second supporting surface 212 includes a plurality of, and one or more first supporting surfaces 211 and one or more second supporting surfaces 212 can be staggered along the first direction; that is, one or more grooves are distributed along the first direction on the mounting surface 12, the first mounting surface 121 can be located at the bottom surface of the groove, and the second mounting surface 122 is on one side or both sides of the groove; one or more protrusions are distributed along the first direction on the supporting surface 21, the first supporting surface 211 is the top surface of the protrusion, and the second supporting surface 212 is located on one side or both sides of the protrusion.

[0082] Providing the mounting surface 12 and the supporting surface 21 with complementary groove and protrusion structures can also improve the structural strength of the supporting member 2.

[0083] Please refer to Figure 12 and Figure 13In one embodiment, the mounting surface 12 has multiple mounting surfaces with height differences distributed along the second direction. Correspondingly, the supporting surface 21 has multiple supporting surfaces with height differences distributed along the second direction. The mounting surface 12 includes multiple first mounting surfaces 121 and multiple second mounting surfaces 122, which are alternately distributed along the second direction. The supporting surface 21 includes multiple first supporting surfaces 211 and multiple second supporting surfaces 212, which are alternately distributed along the second direction.

[0084] The multiple first mounting surfaces 121 and the multiple second mounting surfaces 122 distributed along the second direction form multiple convex tooth-like structures, and the multiple first supporting surfaces 211 and the multiple second supporting surfaces 212 distributed along the second direction also form a pair of concave tooth-like structures. The two are staggered and complementary to each other, which can also improve the structural strength of the support member 2 and realize the limited fixation of the bed panel 1 relative to the support member 2 in the front-to-back direction and the left-to-right direction.

[0085] Please refer to Figure 5 In one embodiment, the support member 2 is provided with a mounting groove 22, and the mounting groove 22 has an opening. The opening of the mounting groove 22 is located on the lower surface of the support member 2. The mounting groove 22 can be located directly below the second supporting surface 212. The mounting groove 22 can be used to install screws and other fixing connectors 3. Part of the fixing connector 3 can be hidden in the mounting groove 22. The mounting groove 22 provides a hidden space to prevent the fixing connector 3 from being exposed and interfering with other components.

[0086] In one embodiment, a hollow structure such as a cavity may be provided in the support member 2. The hollow structure reduces the amount of support member 2 used and reduces the weight of the support member 2 without reducing the structural strength of the support member 2, so that the doctor can move the bed board assembly 10 more easily and it is convenient for the installer to install it.

[0087] Please refer to Figure 2 and Figure 14 In one embodiment, the bed board assembly 10 is mounted on the base 20 in a planarly movable manner, and the bed board assembly 10 can move horizontally in the left-right direction and the front-back direction.

[0088] The support member 2 of the bed board assembly 10 is movably connected to the base 20 , and the support member 2 can move along the left-right direction and the front-back direction of the bed board 1 .

[0089] The lower ends of the two longitudinal beams of the support member 2 are respectively provided with movable grooves 24 extending in the left and right directions. The openings of the movable grooves 23 are located on the lower surface of the longitudinal beams of the support member 2, that is, the movable grooves 23 are extended along the length direction of the support member 2.

[0090] A movable connector 202 is mounted on the upper end of the base 20. One end of the movable connector 202 extends to a rolling or sliding connection with the movable groove 23. The end of the movable connector 202 connected to the movable groove 23 is provided with a roller, such as a limit bearing or a rubber wheel. A horizontal baffle 24 is mounted at the opening of the movable groove 23. The baffle 24 and the support member 2 can be integrated into a structure, or the baffle 24 can be fixed to the support member 2 by screws, welding, or other means.

[0091] The diameter of the rolling wheel is equal to the height of the movable groove 23 where the baffle 24 is located. The rolling wheel can roll along the top surface of the movable groove 23 and the inner side surface of the baffle 24, so that the bed board assembly 10 and the base 20 form a rolling sliding connection. The bed board assembly 10 can be formed in the movable groove 23 by the rolling wheel, thereby realizing left and right movement of the bed board assembly 10 relative to the base 20.

[0092] A movable frame 203 can be mounted on the upper end of the base 20. The movable frame 203 can move relative to the base 20 along the front-to-back direction of the bed board assembly 10. The movable connector 202 is mounted on the movable frame 203, and the bed board assembly 10 is mounted on the movable frame 203. The bed board assembly 10 can move left and right relative to the movable frame 203, and can also move forward and backward together with the movable frame 203. By providing the movable frame 203 on the base 20, the bed board assembly 10 can move left and right and forward and backward.

[0093] In other embodiments, a movable connecting member is installed at the lower end of the support member 2, and a corresponding movable groove 23 is provided at the upper end of the base 20, which can also realize the forward and backward movement of the bed board assembly 10.

[0094] In other embodiments, the movable connecting member may also be configured as other structures, for example, a universal ball or the like may be provided at the end of the movable connecting member.

[0095] Please refer to Figure 14 In one embodiment, a first electromagnetic adsorption component 4 is installed on the lower surface of the support member 2. The first electromagnetic adsorption component 4 is a passive magnetic adsorption component such as a metal plate that can be electromagnetically adsorbed. For example, the first electromagnetic adsorption component 4 is an iron plate or a steel plate.

[0096] A second electromagnetic adsorption component 204 can be installed at the upper end of the base 20. The second electromagnetic adsorption component 204 is an active magnetic adsorption component such as an electromagnet. The second electromagnetic adsorption component 204 can be adsorbed, fixed, and separated from the first electromagnetic adsorption component 4 by turning the power on and off. When the second electromagnetic adsorption component 204 is in the adsorbed and fixed state with the first electromagnetic adsorption component 4, the bed board assembly 10 cannot move in a plane. When the second electromagnetic adsorption component 204 is separated from the first electromagnetic adsorption component 4, the bed board assembly 10 can move forward and backward and left and right relative to the base 20.

[0097] The first electromagnetic adsorption member 4 can improve the stability of the bed plate assembly 10 when it is not moving. The electromagnetic adsorption method is used to lock and unlock the translation of the bed plate assembly 10, which can be driven by an electric motor, has a simple structure, and is easy for doctors to operate.

[0098] In other embodiments, the second electromagnetic attraction member 204 may also be mounted on the movable frame 203. The magnetic attraction between the first electromagnetic attraction member 4 and the second electromagnetic attraction member 204 is used to limit the locking and unlocking of the left-right movement of the bed board assembly 10. Locking and unlocking the front-back movement of the bed board assembly 10 may be achieved by installing an additional electromagnetic attraction member between the movable frame 203 and the base 20.

[0099] In other embodiments, the support member 2 is made of electromagnetic adsorption material, and the support member 2 is an electromagnetic adsorption member, which can also realize electromagnetic adsorption locking and unlocking of the bed board assembly 10 for translation, and realize positioning of the support member on the base 20 by electromagnetic adsorption, thereby improving the stability of the bed board assembly 10 in the locked state.

[0100] In other embodiments, the lower surface of the support member 2 may be provided with a concave structure such as a socket, and the base 20 may be provided with a plug-in structure such as an electrically retractable plug-in rod. When the plug-in rod is connected to the socket, the bed board assembly 10 can be translated and locked. When the plug-in rod is separated from the socket, the bed board assembly 10 can be translated and unlocked.

[0101] In one embodiment, a bed plate assembly of an X-ray imaging system is provided. This bed plate assembly is the bed plate assembly 10 in any of the above embodiments. The bed plate assembly 10 of this embodiment can be installed on a base 20 of the X-ray imaging system for use.

[0102] The bed board assembly of this embodiment can be fixedly or detachably connected to the base 20 of the X-ray imaging system to meet different usage requirements.

[0103] In one embodiment, an X-ray imaging system is provided. The X-ray imaging system includes a transmitting device and a detection bed in any of the above embodiments.

[0104] The transmitting device can be a suspended structure or a column structure. The transmitting device includes a mounting frame and a head. The head is moved by the mounting frame. The head is used to transmit X-rays to irradiate the object to be detected carried by the detection bed.

[0105] The receiving device is a flat panel detector, which can be mounted on the mounting bracket 201 of the base 20 to receive X-rays passing through the object to be detected and generate X-ray data and detection images.

[0106] In the X-ray imaging system of this embodiment, since the mounting surface 12 of the bed panel 1 is provided with a first mounting surface 121 and a second mounting surface 122 with a height difference, and the supporting surface 21 is provided with a corresponding first supporting surface 211 and a second supporting surface 212 with a height difference, after the bed panel 1 is stacked and installed on the support member 2, the local height of the support member 2 can be increased without increasing the thickness of the bed panel assembly 10; in other words, the bed panel assembly 10 can increase the local thickness of the support member 2 while ensuring a relatively thin overall thickness, thereby improving the structural strength of the support member 2, thereby achieving the advantages of both ultra-thinness and sufficient structural strength. Reducing the thickness of the bed panel assembly 10 can shorten the distance between the object to be detected and the flat-panel detector, which is beneficial to improving the imaging quality; and, since the bed panel 1 and the support member 2 are fixed in a stacked manner, the upper surface of the bed panel 1 can be fully flat, which is convenient for the object to be detected to pass through the bed and improves the aesthetics.

[0107] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
