Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a camera assembly and a medical imaging device. Background Technology

[0002] Currently, medical imaging equipment is being used more and more widely to scan subjects (such as the human body) to obtain medical images of specific areas, providing useful information for medical diagnosis.

[0003] Medical imaging equipment includes computed tomography (CT) equipment, magnetic resonance imaging (MRI) equipment, positron emission tomography (PET) equipment, and single photon emission computed tomography (SPECT) equipment.

[0004] In some medical imaging devices, an automatic positioning camera is required as an aid to capture the position, body contour, and surface features of the object being examined, so as to achieve automatic positioning of the object. The medical imaging device can automatically adjust scanning parameters, such as scanning range and angle, based on the information provided by the automatic positioning camera, to ensure the accuracy and integrity of the scanned area. Using an automatic positioning camera can quickly complete the positioning work and improve the scanning efficiency of the medical imaging device.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Utility Model Content

[0006] The inventors discovered that in existing medical imaging equipment, the automatic positioning camera is typically mounted on the ceiling, meaning it's integrated with the room structure. In this case, subsequent installation of the medical imaging equipment requires a more complex mechanical structure for the automatic positioning camera to adjust to the equipment's location. Furthermore, it's difficult for on-site engineers to determine the exact positions of both the automatic positioning camera and the medical imaging equipment. In other medical imaging devices, the automatic positioning camera is mounted on the front or top cover of the device's housing. However, during maintenance or parts replacement, the housing with the automatic positioning camera is disassembled, and after reinstallation, the automatic positioning camera still needs to be reinstalled and its position calibrated. This reduces the operational efficiency of the medical imaging equipment.

[0007] To address at least one of the aforementioned technical problems, embodiments of this application provide a camera assembly and a medical imaging device. The camera of the camera assembly is fixed to the frame of the medical imaging device via a fixing part. This makes it easy to determine the position of the camera assembly and the medical imaging device, facilitating installation and adjustment. Furthermore, when the medical imaging device is maintained or parts are replaced, it is not necessary to disassemble the camera assembly or recalibrate its position, thereby improving the working efficiency of the medical imaging device.

[0046] Referring to the accompanying drawings, the foregoing and other features of the embodiments of this application will become apparent from the following description. Specific embodiments of this application are specifically disclosed in the description and drawings, illustrating partial implementations in which the principles of the embodiments of this application can be adopted. It should be understood that this application is not limited to the described embodiments; rather, the embodiments of this application include all modifications, variations, and equivalents falling within the scope of the appended claims.

[0049] Features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, combined with features in other embodiments, or substituted for features in other embodiments. The term "comprising / including" as used herein means the presence of a feature, integral, step, or component, but does not exclude the presence or addition of one or more other features, integrals, steps, or components.

[0050] Figure 1 This is a schematic diagram of a medical imaging device according to an embodiment of this application. Taking a CT imaging device as an example, it schematically illustrates the situation of a CT imaging device 100. Figure 1 As shown, the CT imaging device 100 includes a scanning gantry 101 and a patient table 102; the scanning gantry 101 has an X-ray source 103 that projects an X-ray beam toward a collimator or detector assembly 104 on the opposite side of the scanning gantry 101. The subject 105 can lie flat on the patient table 102 and move into the scanning gantry opening 106 as the patient table 102 moves; medical image data of the subject 105 can be obtained by scanning with the X-ray source 103.

[0051] Figure 2 This is a schematic diagram of a medical imaging system according to an embodiment of this application. Again, taking a CT imaging system as an example, a block diagram of a CT imaging system 200 is schematically shown. Figure 2 As shown, the detector assembly 104 includes multiple detector units 104a and a data acquisition system (DAS) 104b. The multiple detector units 104a sense projected X-rays passing through the object being detected 105.

[0052] DAS104b converts the collected information into projection data based on the sensing of detector unit 104a for subsequent processing. During the scan that acquires X-ray projection data, the scanning gantry 101 and the components mounted thereon rotate around the rotation center 101c.

[0053] The rotation of the scanning gantry 101 and the operation of the X-ray source 103 are controlled by the control mechanism 203 of the CT imaging system 200. The control mechanism 203 includes an X-ray controller 203a that provides power and timing signals to the X-ray source 103, and a scanning gantry motor controller 203b that controls the rotational speed and position of the scanning gantry 101. The image reconstruction unit 204 receives projection data from the DAS 104b and performs image reconstruction. The reconstructed image is transmitted as input to the computer 205, which stores the image in a mass storage device 206.

[0054] Computer 205 also receives commands and scanning parameters from the operator via console 207. Console 207 has some form of operator interface, such as a keyboard, mouse, voice-activated controller, or any other suitable input device. An associated display 208 allows the operator to view reconstructed images and other data from computer 205. Commands and parameters provided by the operator are used by computer 205 to provide control signals and information to DAS 104b, X-ray controller 203a, and scanning gantry motor controller 203b. Additionally, computer 205 operates patient table motor controller 209, controlling patient table 102 to position the subject 105 and scanning gantry 101. Specifically, patient table 102 moves the subject 105, wholly or partially, through... Figure 1 The scanning rack opening is 106.

[0055] The camera assembly and medical imaging device of the present application embodiments are described below with reference to the accompanying drawings.

[0056] Figure 3 This is a schematic diagram of a medical imaging device in which the camera component of an embodiment of this application is installed. Figure 4 yes Figure 3 An exploded schematic diagram of the medical imaging device shown. Figure 5This is a schematic diagram of a camera component according to an embodiment of this application. Figure 6 yes Figure 5 An exploded view of the camera assembly shown.

[0057] like Figure 3 and Figure 4 As shown in this embodiment, the camera assembly 10 is configured on the medical imaging device 20, which includes a frame 21 and a frame housing 22 covering the frame 21. The camera assembly 10 is mounted on the frame 21 independently of the frame housing 22.

[0058] like Figure 5 and Figure 6 As shown in the embodiment of this application, the camera assembly 10 includes a fixing part 30 and a camera part 40. The fixing part 30 is mounted on the frame 21, and the camera part 40 includes a camera bracket 41 fixed to the fixing part 30 and a camera 42 fixed to the camera bracket 41.

[0059] In this embodiment, the fixing part 30 of the camera assembly 10 is mounted on the frame 21 of the medical imaging device 20, that is, the camera assembly 10 is directly fixed to the frame 21 without being installed to the medical imaging device 20 and / or its frame 21 by means of mounting to the frame housing 22.

[0060] According to the above embodiment, the camera assembly 10 is fixed to the frame 21 independently of the frame housing 22. Therefore, the installation of the camera assembly 10 is not dependent on or subordinate to the frame housing 22. On the one hand, the camera assembly 10, as an independent structure, is easy to install and adjust; on the other hand, the relative position of the camera assembly 10 to the medical imaging equipment can be accurately set or determined. Furthermore, when maintaining or replacing components inside the frame housing 22 of the medical imaging equipment 20, it is not necessary to disassemble the camera assembly 10; conversely, when maintaining or replacing the camera assembly 10, it is not necessary to disassemble the frame housing 22, thereby improving the efficiency of maintaining the medical imaging equipment.

[0061] In some embodiments, such as Figure 5 and Figure 6 As shown, the camera assembly 10 also includes a support portion 50, one end of which is fixed to the fixing portion 30, and the other end of which is connected to the aforementioned camera bracket 41.

[0062] In this embodiment, the structure of the support portion 50 is not limited; in some possible implementations, such as... Figure 6 As shown, the support portion 50 includes a first support portion 51 and a second support portion 52 covering the first support portion 51. A camera cable 47 for transmitting signals (such as video signals, control signals, etc.) and power is disposed in the support portion 50.

[0063] by Figure 6 For example, the support part 50 is divided into two parts. The part located at the bottom of the figure is called the first support part 51, and the part located at the top of the figure is called the second support part 52. The second support part 52 can cover the first support part 51 and wrap the camera cable 47 in the support part 50.

[0064] like Figure 5 As shown, the first support portion 51 and the second support portion 52 form a long handle or cantilever shape after assembly. The camera portion 40 is supported by the support portion 50, which allows the position of the camera portion 40 to be not limited to the vicinity of the fixed portion 30, thus improving the flexibility of the position of the camera portion 40.

[0065] Figure 5 and Figure 6 The structure of the support portion 50 shown is merely an example. The support portion 50 may also have other shapes or extend to other positions, depending on the needs of the medical imaging equipment. This application does not impose any limitations. Furthermore, the first support portion 51 and the second support portion 52 may be assembled in a fitting structure or by screws, etc. This application is not limited to these.

[0066] The structure of the fixing part 30 of the camera assembly 10 according to the present application embodiment will be described below.

[0067] Figure 7 This is a partially enlarged schematic diagram of a medical imaging device according to an embodiment of this application, showing the structure of the fixing part 30 of the camera assembly 10.

[0068] In some embodiments, such as Figure 7 As shown, the fixing part 30 includes a first base 31 fixed to the frame 21 and a second base 32 fixed to the first base 31, and one end of the support part 50 is fixed to the second base 32.

[0069] In the above embodiments, the method of fixing the support portion 50 and the second base 32 is not limited. For example, the support portion 50 and the second base 32 can be fixed by screws, or by adhesive bonding, etc., and this application does not impose any limitations.

[0070] In some possible implementations, such as Figure 6 As shown, one end of the support portion 50, that is, Figure 6 The lower end of the first support portion 51 shown is fixed to the second base 32; the other end of the support portion 50, that is, Figure 6 The upper end of the first support portion 51 shown is connected to the camera bracket 41. Thus, the support portion 50 achieves fixation relative to the fixing portion 30 and supports the camera bracket 41.

[0071] Figure 8 This is a partially enlarged schematic diagram of a camera assembly according to an embodiment of this application, showing the structure of the first base 31 and the second base 32 and their mutual fixing or connection structure.

[0072] In some embodiments, such as Figure 7 and Figure 8 As shown, the first base 31 includes a first connecting plate 311 connected to the frame 21 and a second connecting plate 312 connected to the second base 32. The first connecting plate 311 and the second connecting plate 312 are perpendicular to each other, or in other words, the extension direction of the first connecting plate 311 and the extension direction of the second connecting plate 312 are perpendicular to each other.

[0073] According to the above embodiment, by setting an L-shaped first base 31, it can be connected to both the frame 21 and the second base 32, thereby fixing the camera assembly 10 to the frame 21 and facilitating the disassembly, adjustment and installation of the camera assembly 10.

[0074] Figure 9 This is another partially enlarged schematic diagram of the camera assembly according to an embodiment of this application, showing the structure of the second connecting plate 312 and the position of the second base 32 relative to the second connecting plate 312. Figure 9 (a) shows the second base 32 in a first position relative to the second connecting plate 312. Figure 9 (b) shows the second base 32 in the second position relative to the second connecting plate 312.

[0075] like Figure 9 As shown, in some examples, a pair of guide members P are provided on the bottom surface of the second base 32 to assist in the quick installation of the second base 32 onto the first base 31. For example, the guide member P can be cylindrical, conical, triangular, or other suitable shapes. For example, the guide member P can be an integral structure with the second base 32, or it can be two separate parts connected by snap-fit, screws, welding, or other suitable methods. The second connecting plate 312 is provided with two guide grooves for accommodating the guide members P, referred to as the first guide groove 31(a) and the second guide groove 31(b), as shown... Figure 8 As shown, in some examples, a guide groove, referred to as the third guide groove 31(c), is provided on the first connecting plate 311. When the second base 32, after the camera assembly 10 is assembled, is connected to the first base 31, the three guide grooves 31(a), 31(b), and 31(c) guide the installation between the two bases, thereby accurately positioning the second base 32 and the camera assembly 10. In the above example, the three guide grooves 31(a), 31(b), and 31(c) have shapes corresponding to the shape of the guide member P.

[0076] For example, when the second base 32, after the camera assembly 10 is assembled, is connected to the first base 31, the relative positional relationship between the first base 31 and the second base 32 is as follows: Figure 9 As shown in (a), at this time along Figure 9 The arrow in (a) points in the direction that pushes the second base 32, and the guide P slides in the first guide groove 31(a) and the second guide groove 31(b), so that the second base 32 is located in the direction indicated by the arrow. Figure 9 The state shown in (b).

[0077] In some examples, such as Figure 9 As shown, the first guide groove 31(a) and the second guide groove 31(b) are located in the extending direction of the second connecting plate 312. Figure 9 It lies on the center line O (shown in the left-right direction) and extends along that center line O. In some examples, such as... Figure 8 and Figure 9 As shown, the second guide groove 31(b) and the third guide groove 31(c) can be disposed at the junction of the first connecting plate 311 and the second connecting plate 312, and as... Figure 8 As shown, the second guide groove 31(b) and the third guide groove 31(c) are connected, which facilitates quick alignment and installation when the second base 32 after the camera assembly 10 is assembled is connected to the first base 31.

[0078] In some examples, such as Figure 9 As shown, one end of the first guide groove 31(a) ( Figure 9 As shown on the left end, such as Figure 9 As shown in (a), it can be configured as an elliptical structure extending along the center line O, with the other end of the first guide groove 31(a) ( Figure 9 As shown on the right end, such as Figure 9 As shown in (b), it can be set to be approximately circular with a diameter greater than that of the guide P, thereby avoiding interference with the guide P when adjusting the position of the second base 32 relative to the first base 31.

[0079] In some examples, such as Figure 9 As shown, one end of the second guide groove 31(b) ( Figure 9 As shown on the left end, such as Figure 9 (a) can be configured as an elliptical structure extending along the center line O, and the other end of the second guide groove 31(b) Figure 9 As shown on the right end, such as Figure 9 (b) can be set to a direction perpendicular to the extension direction of the center line O. Figure 9 The elliptical structure extends in the vertical direction as shown, and can communicate with the third guide groove 31(c) provided on the first connecting plate 311, as shown. Figure 8 As shown. This facilitates the alignment and installation of the second base 32 and the first base 31.

[0080] Figure 9 The examples provided are merely illustrative and are not intended to limit the scope of this application. In the embodiments of this application, the first guide groove 31(a) and the second guide groove 31(b) may also be provided at other locations on the second connecting plate 312, such as being arranged side by side in the vertical direction on one side (upper or lower) of the center line O, or extending in the horizontal direction. For example, they may be symmetrically arranged on the upper and lower sides of the center line O with the center line O as the axis, etc. Furthermore, the first guide groove 31(a) and the second guide groove 31(b) may also be provided in other shapes.

[0081] In some examples, such as Figure 8 and Figure 9 As shown, the third guide groove 31(c) is located on the first connecting plate 311 near the second connecting plate 312 and communicates with the second guide groove 31(b), that is, it is located in a direction perpendicular to the extending direction of the first connecting plate 311. Figure 9 The center position (shown in the up-down direction) facilitates the installation and positioning of the second base 32 and the first base 31.

[0082] According to the above embodiment, by providing a first guide groove 31(a) and a second guide groove 31(b) along the center line of the second connecting plate 312, and making the second guide groove 31(b) communicate with the third guide groove 31(c) provided on the first connecting plate 311, the installation speed is faster and the stability is better.

[0083] In some embodiments, such as Figure 7 As shown, the first connecting plate 311 can be fixed to the frame 21 by the first fastener S1.

[0084] This application does not limit the number of the first fastener S1, so as to Figure 7 For example, the first connecting plate 311 can be fixed to the frame 21 by four first fasteners S1. The first fasteners S1 can be screws, etc. This application is not limited to this. The frame 21 and the first connecting plate 311 can also be fixed by fewer or more first fasteners S1, or by other means, such as bonding, fitting, snap-fit, interference fit, etc. This application does not impose any restrictions.

[0085] In some embodiments, such as Figure 8 and Figure 9 As shown, the second connecting plate 312 can be fixed to the second base 32 by the second fastener S2.

[0086] This application does not limit the number of the second fastener S2, so that... Figure 9 For example, the second connecting plate 312 can be fixed to the second base 32 by eight second fasteners S2. These eight second fasteners S2 can be evenly distributed on both sides of the center line O with the center line O as the boundary, and the second fasteners S2 distributed on the same side of the center line O can have any installation position. This application does not limit this.

[0087] In some embodiments, such as Figure 8 and Figure 9 As shown, a pair of baffles 34 are installed on the side of the second connecting plate 312 away from the second base 32. The pair of baffles 34 are located on both sides of the center line O extending in the direction of the second connecting plate 312. Thus, by providing baffles 34 on the lower surface of the second connecting plate 312, it is possible to prevent the second fastener S2 from falling into the interior of the medical imaging device 20 when it comes loose.

[0088] In this embodiment, the specific structure of the baffle 34 is not limited. Figure 8 The left side shows a cross-section of an example of the structure of baffle 34.

[0089] In some possible implementations, such as Figure 8 As shown, the baffle 34 has a first portion 341 fixed to the second connecting plate 312 by a second fastener S2, a second portion 342 extending from one end of the first portion 341 near the center line O in an extension direction perpendicular to the second connecting plate 312, and a third portion 343 extending from the extension end of the second portion 342 in an extension direction parallel to the second connecting plate 312. That is, the baffle 34 can be formed as follows: Figure 8 The structure shown.

[0090] In the above embodiments, such as Figure 8 and Figure 9 As shown, the two second fasteners S2 on one side of the center line O ( Figure 9 The two second fasteners S2 shown, which are away from the center line O, can be fixed to the second connecting plate 312 by means of the first part 341. The other two second fasteners S2 on the side of the center line O ( Figure 9 The two second fasteners (S2) near the center line O shown can be directly fixed to the second connecting plate 312 by passing through the through holes provided on the third part 343.

[0091] According to the above embodiment, by setting the baffle 34, the second fastener S2 can be prevented from falling off and into the medical imaging device, thereby affecting the medical imaging device.

[0092] The following is based on Figure 8 The baffle 34 and the second fastener S2 will be described using an example.

[0093] like Figure 8 As shown, for a baffle 34, at the end furthest from the observation direction, the first base 31 (second connecting plate 312) is fixed to the second base 32 by two second fasteners S2. After the second fasteners S2 are unscrewed, they fall vertically downwards under the influence of gravity, that is, along... Figure 8 The first part 341 of the baffle 34 is located at one end of the second fastener S2 in the Y1 direction, and the third part 343 of the baffle 34 is located in the horizontal direction, that is, the third part 343 of the first baffle 34 is set to be perpendicular to the Y1 direction. Figure 8 For example, the second fastener S2 can be fixed in the Y1 direction. That is, after the second fastener S2 is fixed, its axis is located in the Y1 direction. The first part 341 of the baffle 34 is located at one end of the second fastener S2 in the Y1 direction and is set to be perpendicular to the Y1 direction. When the second fastener S2 is unscrewed, it can detach and fall along the Y1 direction. At this time, the third part 343 of the baffle 34 can catch the unscrewed second fastener S2 to prevent the second fastener S2 from falling into the interior of the medical imaging device 20 after it detaches.

[0094] In the above embodiments, with Figure 8 For example, only two second fasteners S2 at the end of the first base 31 away from the viewing direction are shown. This application is not limited to this; second fasteners S2 and baffles 34 can also be provided at the end of the first base 31 closer to the viewing direction, such as... Figure 9 As shown. Furthermore, the number of second fasteners S2 can also be other numbers, and this application is not limited to this.

[0095] According to the above embodiments, when the second fastener S2 falls off or needs to be disassembled, the baffle 34 can prevent the second fastener S2 from falling into the interior of the medical imaging device.

[0096] In the above embodiments, the implementation of the second fastener S2 is not limited. The second fastener S2 can be a screw, a rivet, or other types of fasteners. Furthermore, the second fastener S2 can be a captive screw, a specially designed screw that will not fall out of its mounting hole even after being completely loosened. In some possible implementations, a limiting structure is provided below the screw head or threads, and a retaining ring, a retaining ring, or a resilient washer is provided in the mounting hole. The captive screw can be integrated with the panel or housing. For details regarding captive screws, please refer to relevant technologies; further details will not be elaborated here.

[0097] In some embodiments, such as Figure 6As shown, the fixing part 30 also has a cable hole 35 and a cable cover 36. The camera cable 47 from the support part 50 can enter the interior of the medical imaging device 20 through the cable hole 35, and the cable cover 36 covers the cable hole 35.

[0098] like Figure 6 As shown, the cable hole 35 can be set on the second base 32. Therefore, by directly utilizing the second base 32 to set the cable hole 35, the component utilization rate is improved, and the structure of the camera assembly 10 is simplified. Furthermore, using the cable cover 36 to cover the cable hole 35 increases the aesthetics of the device. Also, when inspecting the camera assembly 10, the cable cover 36 can be directly removed to observe the condition of the camera cable 47 without disassembling the camera assembly 10.

[0099] In the above embodiments, there are no restrictions on the fixing method of the cable cover 36 and the cable hole 35. A snap-fit ​​structure or fasteners can be used for fixing. This application is not limited to this.

[0100] In some embodiments, such as Figures 3 to 7 As shown, the shape of the exposed portion of the second base 32 matches that of the frame housing 22.

[0101] In the above embodiment, although the fixing part 30 is mounted on the frame 21, after the medical imaging device 20 is installed, such as Figure 3 As shown, only a portion of the second base 32 in the fixing part 30 is exposed outside the frame housing 22, the first base 31 is covered by the second base 32, and the shape of the exposed portion of the second base 32 matches the frame housing 22. This makes the fixing part 30 more secure against the frame housing 22 and improves the appearance of the medical imaging device 20.

[0102] According to the above embodiment, the camera unit 40 is fixed to the frame 21 by the fixing part 30 and is independent of the frame housing 22 of the medical imaging device 20. Therefore, when the medical imaging device 20 is disassembled for maintenance or replacement of parts by removing the frame housing 22, it is not necessary to disassemble the camera assembly 10 and it is not necessary to recalibrate the position of the camera 42, thereby improving the working efficiency of the medical imaging device 20.

[0103] The connection between the camera unit 40 and the support unit 50 and the camera bracket 41 in the embodiments of this application will be described below.

[0104] Figure 10 This is another partially enlarged schematic diagram of the camera assembly according to an embodiment of this application, showing the structure of the camera section 40.

[0105] In some embodiments, such as Figure 10As shown, the camera bracket 41 includes a first bracket 43 mounted on the support portion 50 and a second bracket 44 fixed to the first bracket 43 and fixed to the camera 42; the first bracket 43 can be rotated and adjusted relative to the support portion 50 in a first direction, and the second bracket 44 can be rotated and adjusted relative to the first bracket 43 in a second direction.

[0106] Figure 11 This is a schematic diagram of the camera bracket 41 of the camera assembly 10 according to an embodiment of this application, showing the structure of the first bracket 43. Figure 12 This is another schematic diagram of the camera bracket 41 of the camera assembly 10 according to an embodiment of this application, showing the structure of the second bracket 44 and the camera 42.

[0107] In the above embodiments, the first direction is as follows: Figure 11 The X1 direction is shown, and the second direction is as follows: Figure 12 The X2 direction is shown. The first direction and the second direction can be perpendicular, but this application is not limited to this. Depending on the structure and needs of the camera assembly 10, the first direction and the second direction may not be perpendicular.

[0108] In some embodiments, such as Figure 11 As shown, the first bracket 43 is fixed to the support portion 50 by the first connector 45, and the second bracket 44 and the camera 42 (see...) Figure 12 Rotate within a first angular range about the first axis X3; for example Figure 12 As shown, the second bracket 44 is fixed to the first bracket 43 by the second connector 46, and the second bracket 44 and the camera 42 are tilted within a second angle range about the second axis X4. Wherein, Figure 11 In the middle, the first axis X3 passes through the first connector 45 and is perpendicular to the plane in which the view is located. Figure 12 In the middle, the second axis X4 passes through the second connector 46 and is perpendicular to the plane in which the view is located.

[0109] Figure 13 This is another schematic diagram of the camera bracket 41 of the camera assembly 10 according to an embodiment of this application, showing the view of the camera 42 and the camera bracket 41 from the bottom of the camera 42.

[0110] In some embodiments, such as Figure 13 As shown, the first bracket 43 includes a first fixing part 43(a) and a second fixing part 43(b). The first fixing part 43(a) is fixed to the support part 50 by a first connector 45, and the second bracket 44 is fixed to the second fixing part 43(b) by a second connector 46. At this time, as... Figure 13As shown, the first axis X3 passes through the first connector 45 and is perpendicular to the plane where the first fixing part 43(a) is located, and the second axis X4 passes through the second connector 46 and is perpendicular to the plane where the second fixing part 43(b) is located.

[0111] like Figure 10 and Figure 11 As shown, the first fixing part 43(a) can rotate about the first axis X3 within a first angular range in the first direction X1, thereby, as Figure 13 As shown, by rotating the first fixing part 43(a) about the first axis X3 in the first direction X1, the second fixing part 43(b), the second bracket 44 fixed to the second fixing part 43(b), and the camera 42 fixed to the second bracket 44 can be rotated together in the first direction X1. Thus, by rotating the first fixing part 43(a), the shooting range or field of view of the camera 42 in the first direction X1 can be adjusted.

[0112] For the second bracket 44, as Figure 12 and Figure 13 As shown, the second bracket 44 is fixed to the second fixing part 43(b) of the first bracket 43 via the second connector 46, and the second bracket 44 can rotate about the second axis X4 within a second angle range in the second direction X2. Thus, as... Figure 12 As shown, by rotating the second bracket 44 about the second axis X4 in the second direction X2, the camera 42 can be rotated in the second direction, thereby adjusting the shooting range or field of view of the camera 42 in the second direction X2.

[0113] In some other embodiments, such as Figure 6 and Figure 13 As shown, the support portion 50 has an opening H1, and the camera 42 is located inside the opening H1. The first fixing portion 43(a) of the first bracket 43 is fixed to one end of the opening H1 by the first connector 45 (e.g., Figure 13 The second fixing part 43(b) of the first bracket 43 can extend to the other end of the opening H1 (i.e., the upper end of the opening H1 shown), the second fixing part 43(b) of the first bracket 43 can extend to the other end of the opening H1 (i.e., the upper end of the opening H1 shown). Figure 13 The lower end of the opening H1 shown is opposite to the upper end of the opening H1 where the first fixing part 43(a) is located, and the end of the second fixing part 43(b) that is away from the first fixing part 43(a) is... Figure 13 The lower end of the second fixing part 43(b) shown can also be provided with the same structure as the first fixing part 43(a) (not shown in the figure), and fixed to the support part 50 by a connector. That is, the first fixing part 43(a) is provided at both ends of the second fixing part 43(b), thereby the first bracket 43 can be symmetrically positioned vertically (here, vertical symmetry means from the bottom of the bracket). Figure 13The first support 43 is set up symmetrically (observed from the angle shown) and can rotate around the first axis X3, which improves the stability of the first support 43.

[0114] In the above embodiments, correspondingly, the second bracket 44 can be configured to be installed by the second connector 46 at or near the middle position of the first bracket 43 (here, the middle position refers to the position from the middle position of the first bracket 43). Figure 13 (The angle shown is the middle position in the vertical direction) and can be rotated around the second axis X4.

[0115] In some embodiments, the first angle range is ±2° relative to the default position, and the second angle range is ±3° relative to the default position. The default position can be one where the camera 42's field of view or shooting range covers the entire scanning object or the scanning bed carrying the scanning object, achieved by rotating the first support 43 and the second support 44. For example, in a two-dimensional photograph captured by the camera 42, the boundary of the scanning bed is parallel to the boundary of the two-dimensional photograph.

[0116] In other embodiments, the first bracket 43 and the second bracket 44 can adjust the camera 42 to other pre-set positions to achieve the purpose of adjusting the camera 42 for auxiliary positioning, which is not limited in this application.

[0117] by Figure 11 For example, the first angle range is ±2° relative to the default position, that is, the first fixing part 43(a) can rotate 2° to the left or right relative to the default position. At this time, the rotation angle α of the first fixing part 43(a) is 4°. Figure 12 For example, the second angle range is ±3° relative to the default position. That is, the second bracket 44 can rotate 3° to the left or right relative to the default position. In this case, the rotation angle θ of the second bracket 44 is 6°. In addition, other values ​​can be set for the first and second angle ranges according to specific needs, and this application is not limited to these.

[0118] In the above embodiments, the first connector 45 and the second connector 46 can be screws or other fasteners. When it is necessary to adjust the shooting range or shooting angle of the camera 42, the first bracket 43 and the second bracket 44 can be rotated by adjusting the tightness of the first connector 45 and the second connector 46, thereby driving the camera 42 to rotate. After the adjustment is completed, the first connector 45 and the second connector 46 are adjusted again to fix the first bracket 43 and the second bracket 44 at the adjusted angle, thereby realizing the rotation adjustment of the first bracket 43 and the second bracket 44.

[0119] In some embodiments, the first connector 45 and the second connector 46 may employ compliant fasteners, which allow limited relative movement (such as rotation or sliding) between the two fastened components and apply a certain resistance or elastic force during movement without requiring the fasteners to be loosened. For example, the compliant fasteners may include articulated fasteners, friction hinges, spring-loaded fasteners, damped joints, and adjustable resistance fasteners.

[0120] Therefore, as Figure 11 and Figure 12 As shown, the camera 42 rotates within a first angle range and in a first direction by rotating the first bracket 43, and the camera 42 rotates within a second angle range and in a second direction by rotating the second bracket 44. This allows the camera 42 to be adjusted so that the user can adjust the camera 42 according to the position of the object being examined and the part of the object that needs to be examined, so that the medical imaging device 20 can locate the object being examined during the scanning process and obtain accurate scan images.

[0121] In some embodiments, such as Figure 6 As shown, the camera unit 40 also includes a top cover 53 and a bottom cover 54, which cover the camera 42 and the camera bracket 41 in the vertical direction of the camera 42.

[0122] like Figure 6 As shown, the top cover 53 of the camera unit 40 covers the camera 42 and the camera bracket 41 from above, and the bottom cover 54 of the camera unit 40 covers the camera 42 and the camera bracket 41 from below. The top cover 53 and the bottom cover 54 completely cover the camera 42 and the camera bracket 41. This application does not limit the method of fixing the top cover 53 and the bottom cover 54; they can be fixed by screws or by clips.

[0123] In some embodiments, such as Figure 6 As shown, the first support portion 51 and the bottom cover 54 are respectively formed with openings H1 and H2, and the camera 42 takes pictures through openings H1 and H2.

[0124] In the above embodiments, the openings H1 and H2 can have appropriate sizes to allow the field of view of the camera 42 to be unobstructed by the first support portion 51 and / or the bottom cover 54 after the camera 42 is rotated and adjusted in two dimensions or directions (X1 and X2) by means of the camera bracket 41. In some embodiments, the openings H1 and H2 can be closed by transparent materials that do not affect the shooting performance of the camera 42, such as optical glass, sapphire glass, quartz glass, polycarbonate, acrylic, fluoride crystals, etc.

[0125] Thus, the camera 42 is housed in a semi-enclosed or enclosed space formed by the top cover 53 and the bottom cover 54. The top cover 53 and the bottom cover 54 can protect the camera 42 and prevent collisions with the camera 42 and camera bracket 41 during the disassembly of the medical imaging device 20, which could damage the camera assembly 10 and affect the accuracy of the position of the camera assembly 10.

[0126] It should be noted that, in the above embodiments, this application does not limit the materials constituting the support part 50, the camera bracket 41, and the fixing part 30. The materials of each component can be plastic, carbon fiber, aluminum alloy, or other materials, as long as they can ensure the normal use of the camera assembly 10 and the medical imaging device 20. This application does not impose any restrictions.

For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0128] According to the above embodiments, the camera assembly is mounted on the frame of the medical imaging equipment via a fixing part. This makes it easy to determine the position of the camera assembly and the medical imaging equipment, facilitating installation and adjustment. Furthermore, when the medical imaging equipment is maintained or parts are replaced, it is not necessary to disassemble the camera assembly or recalibrate its position, thus improving the working efficiency of the medical imaging equipment.

[0129] This application also provides a medical imaging device, which includes a camera assembly 10 as described in the foregoing embodiments, the contents of which are incorporated herein.

[0130] The medical imaging devices described in this article, i.e., devices for acquiring medical image data, can be applied to various medical imaging modalities, including but not limited to computed tomography (CT) devices, magnetic resonance imaging (MRI) devices, positron emission tomography (PET) devices, single-photon emission tomography (SPECT) devices, PET-CT, PET-MR, or any other suitable medical imaging devices.

[0133] Furthermore, medical imaging workstations can be located locally on the medical imaging equipment, meaning they are situated close to the equipment, and both can be located in the same scanning room, radiology department, or within the same hospital. Meanwhile, the medical image cloud platform analysis system can be located away from the medical imaging equipment, for example, in the cloud where it communicates with the equipment.
