Description

Body scanning equipment

[0001] This application claims priority to Chinese patent application No. 202311797685.2, filed on December 25, 2023, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present disclosure relates to the field of detection technology, and in particular to a human body scanning device. Background Art

[0003] The main implementation method of the relevant human body safety inspection system based on X-ray fluoroscopy imaging is that the X-rays and detectors are fixed, and the person being inspected is driven by a conveyor to pass through the X-ray beam surface to complete the scan. The main conveying mechanisms for the person being inspected include belt conveyor, guide rail pedal conveyor, etc.

[0004] Another method is that the person being examined stands still, and the radiation source and detector move relative to the body to complete the scan. The movement of the imaging mechanism mainly includes screw drive, belt drive, steel belt or steel wire rope looped around the C-arm, etc.

[0005] In related technologies, screw transmission involves noise and speed limitation issues. Belt transmission can solve the noise problem, but there may be a risk of prolonged operation in the long term, which will increase the number of maintenance times. The circular winding of steel belts and wire ropes also has the risk of extending the circumference, causing uneven force on both sides of the radiation source and detector, which will lead to travel tolerance problems and misalignment between the radiation and the detector in the long term.

[0054] 1 , 2 , 4 , 9 - 10 show a human body scanning device according to an embodiment of the present disclosure. FIG. 1 includes an outer skin or cover of the device, while FIG. 2 , 4 , 9 - 10 partially removes the outer skin or cover to show the internal structure.

[0055] As shown in Figure 2, the human body scanning device includes two main parts: a support column 200 and an imaging assembly. The imaging assembly is supported by the support column 200 and configured to image the human body. The imaging assembly can move up and down along the support column 200 to scan the human body.

[0056] In an embodiment of the present disclosure, the imaging assembly includes an arm 300. As shown in Figures 5-8, the arm 300 can have any of the following shapes: I-shaped (Figure 6a), L-shaped (Figure 6b), C-shaped (Figure 6c), "["-shaped (Figure 6d), U-shaped, E-shaped (Figure 8), or 6-shaped (Figure 7). It should be understood that the arm 300 can also have other shapes.

[0057] In one embodiment of the present disclosure, as shown in FIG5 , an imaging assembly may include a radiation source 301 located at a first end 306 of an arm 300 and a detector located at a second end 305 of the arm 300 (the detector is not shown in FIG5 , but is disposed within the second end 305). The first end 306 and the second end 305 are opposed to each other so that the radiation source 301 and the detector define a detection volume. In other words, the shape of the arm 300 allows radiation emitted by the radiation source 301 located at the first end 306 to be received by the detector located at the second end 305 of the arm 300. In this embodiment, the first end 306 and the second end 305 are shown as having a certain length, or can be considered as a section or portion of the arm 300. For example, in a "["-shaped arm 300, the first end 306 and the second end 305 are connected by a middle portion (e.g., portion 304 ), and are ends of a certain length, not just tips. It should be understood that the radiation beam emitted by the radiation source 301 can have a fan-shaped or other shape to cover a wide range, thus forming an I-shaped shape on the arm 300. The radiation beam emitted by the radiation source 301 can also illuminate the detector to achieve imaging of the human body. In one embodiment, the radiation beam emitted by the radiation source 301 can have a conical or radial shape. The radiation source 301 can illuminate the desired part of the human body at a suitable height, and the radiation source 301 does not need to be moved to complete the examination.

[0058] In the human body scanning device disclosed herein, as shown in Figures 4 and 5, the imaging assembly includes a beam guide box 302, which is equipped with a collimating mechanism 303 (shown as a slit in Figure 5) to collimate the radiation from the radiation source 301 into a desired beam and illuminate the detector. The radiation source 301 of the imaging assembly can be close to the support column 200. The side of the first end 306 of the arm 300 of the imaging assembly close to the support column 200 is connected to the imaging guide rail 202 provided on the support column 200. The imaging guide rail 202 can bear the lateral force applied by the imaging assembly and keep the arm 300 in a horizontal state or an inclined state. The beam guide box 302 is provided on the side of the first end 306 of the arm 300 of the imaging assembly facing the detector located at the second end 305 of the arm 300. The radiation from the radiation source 301 is emitted through the beam guide box 302, which shapes the radiation from the radiation source 301 into a beam, which can be a fan beam, a pencil beam, etc. FIG5 schematically illustrates a beam guide box 302 having a collimation mechanism 303 (schematically illustrated by an opening slit). The beam guide box 302 can be integrated with a radiation source 301 (e.g., an X-ray machine). The opening slit of the collimation mechanism 303 shown in FIG5 is adjustable to constrain the radiation to an ideal width, ensuring that the radiation beam correctly illuminates the detector.

[0059] In an embodiment of the present disclosure, as shown in FIG7 , the arm 300 may have a “6” shape; as shown in FIG8 , the arm 300 may have an “E” shape. In the embodiments shown in FIG7 and FIG8 , the arm 300 has a transverse rod 307, and a portion of the beam guide box 302 (as shown on the right side) is connected to the transverse rod 307, so that the radiation beam emitted from the beam guide box 302 has a more stable direction. Here, it can be considered that the transverse rod 307 is connected to one end of the outgoing radiation beam of the beam guide box 302, or it can be considered that the end face of the collimation mechanism 303 is connected to the transverse rod 307.

[0060] In one embodiment, the transverse rod 307 is adjustable to adjust the direction of the radiation beam emitted by the beam guide box 302. For example, in the embodiment shown in FIG8 , FIG8 shows a schematic top view of the arm 300. The arm 300 is arranged horizontally, and one end of the transverse rod 307 is connected to the middle portion of the arm 300 and can pivot around the middle portion of the arm 300 (in the vertical plane), thereby allowing the level of the opening of the collimating structure 303 of the beam guide box 302 to be adjusted. For example, as shown in Figure 8, a transverse rod connection portion 308 is provided on the arm 300, and the transverse rod 307 is connected to the middle part of the arm 300 through the transverse rod connection portion 308. The transverse rod connection portion 308 allows the transverse rod 307 to pivot around the transverse rod connection portion 308, or the transverse rod 307 can pivot around the arm 300 through the transverse rod connection portion 308; or in other words, the transverse rod connection portion 308 can swing the transverse rod 307, so that the direction of the outgoing beam of the beam guide box 302 can be changed through the transverse rod 307.

[0061] In another embodiment, the transverse rod connection portion 308 is capable of moving the transverse rod 307 in the up and down direction. By the up and down movement of the transverse rod 307, one end of the outgoing beam of the beam guide box 302 is moved up and down, thereby adjusting the direction of the outgoing beam of the beam. In this embodiment, the transverse rod connection portion 308 allows the transverse rod 307 to reciprocate relative to the arm 300 in a direction perpendicular to the plane defined by the arm 300, that is, in this embodiment, the transverse rod 307 can move up and down to fine-tune one end of the outgoing beam of the beam guide box 302 to achieve alignment of the outgoing beam of the detector. It should be noted that the transverse rod 307 can be regarded as a part of the arm 300, and according to an embodiment of the present disclosure, the transverse rod 307 is a movable transverse rod or an adjustable transverse rod. The transverse rod 307 of the present disclosure can achieve alignment of the beam of radiation emitted by the beam guide box 302 with the detector, and achieve stability of the beam guide box 302. The transverse rod 307 is located between the first end 306 and the second end 305 of the imaging assembly. The position of the transverse rod 307 can be adjusted according to the size of the beam guide box 302. The different descriptions herein are intended to illustrate the position and configuration of the guide rods in the arm 300 and should not be construed as limiting the transverse rod 307 or the arm 300. In other embodiments of the present disclosure, such as the embodiments shown in Figures 1-6 and Figures 9-10, the transverse rod 307 described in this embodiment can be provided. Those skilled in the art should be able to combine the embodiments of the present disclosure based on the description of the present disclosure to derive other embodiments of the present disclosure.

[0062] FIG5 schematically illustrates an embodiment, which includes an imaging assembly. In this embodiment, the imaging assembly includes a horizontally placed "∩"-shaped arm 300 as shown. The two ends of the arm 300 are opposite each other. A radiation source 301 is disposed at the first end 306 of the arm 300, and a detector is disposed at the second end 305 of the arm 300. The radiation beam emitted by the radiation source 301 at the first end 306 of the arm 300 is received by the detector at the second end 305 of the arm 300. The arm 300 is implemented with a smaller size and weight, provides torsional resistance, and reduces detector vibration. The detector converts the radiation into electrical signals, which are transmitted to, for example, an acquisition system of the human body scanning device.

[0063] In the embodiments of the present disclosure, the boom 300 can have various shapes, as schematically shown in FIG6 . Detectors can be arranged along the boom 300 , and thus the detector arrangement can have a shape similar to the boom 300 , such as a C-shape, a U-shape, an I-shape, an E-shape, a 6-shape, or a horizontal "∩" shape. The specific positions of the detectors on the various booms 300 shown in FIG6 are not shown here. However, those skilled in the art will be able to place detectors on the various booms 300 shown in FIG6 as needed based on the description of this disclosure.

[0064] In one embodiment, the human body scanning device may include an energy-absorbing structure. For example, the energy-absorbing structure may include an energy-absorbing portion and a flexible member 410, such as a flexible cord, extending from the energy-absorbing portion. One end of the flexible member 410 is fixedly connected to the second end 305 of the arm 300. The energy-absorbing portion allows the flexible member 410 to be retracted or released so that it can move with the second end 305 of the arm 300. The energy-absorbing portion also allows the flexible member 410 to apply a pulling force to the second end 305 of the arm 300 to prevent vibration. For example, a damping component or a power component may be provided within the energy-absorbing portion. The flexible member 410 can be released from the energy-absorbing portion while applying a force to the flexible member 410, causing it to remain retracted within the energy-absorbing portion. This allows the flexible member 410 to maintain its pulling position against the second end 305 of the arm 300, thereby preventing vibration or trembling of the second end 305. The energy-absorbing portion may be any mechanism or device that achieves the above functions.

[0065] In one embodiment, as shown in Figures 9 and 10 , the energy absorbing portion includes a first energy absorbing portion 401 and a second energy absorbing portion 402. The first energy absorbing portion 401 and the second energy absorbing portion 402 are connected to the second end 305 of the boom 300 from the upper and lower sides of the boom 300 via respective first and second flexible members 410 and 420, respectively, to apply tension to the second end 305 of the boom 300 to prevent the second end 305 of the boom 300 from vibrating. For example, as shown in Figures 9 and 10 , the first energy absorbing portion 401 and the second energy absorbing portion 402 are located at the upper and lower sides of the second end 305 of the boom 300, respectively. It should be understood that the upper and lower positions of the first energy absorbing portion 401 and the second energy absorbing portion 402 are not fixed. The first energy absorbing portion 401, shown at the upper side in the figure, can be fixed to any fixed frame, the top surface of a building, or other elevated point; the second energy absorbing portion 402 can be located at a location on a frame or base at the bottom of the equipment, or on the ground.

[0066] In one embodiment, the energy absorbing portion may include a damping device. A first energy absorbing portion 401 is connected to the second end 305 of the arm 300 via a first flexible member 410, and a second energy absorbing portion 402 is connected to the second end 305 of the arm 300 via a second flexible member 420. During the upward and downward movement of the arm 300, the damping function of the first energy absorbing portion 401 and the second energy absorbing portion 402 suppresses vibration of the arm 300, thereby improving imaging stability and clarity. The first energy absorbing portion 401 and the second energy absorbing portion 402 include winding drums for the first flexible member 410 and the second flexible member 420, respectively accommodating the first flexible member 410 and the second flexible member 420.

[0067] In other embodiments, the first energy absorbing portion 401 and the second energy absorbing portion 402 may be other devices, such as a power device that applies a small pulling force to the second end 305 of the boom 300 through the first flexible member 410 and the second flexible member 420, respectively, while allowing the first flexible member 410 and the second flexible member 420 to move with the second end 305 of the boom 300. The first energy absorbing portion 401 and the second energy absorbing portion 402 include winding drums for the first flexible member 410 and the second flexible member 420, respectively, for storing the first flexible member 410 and the second flexible member 420. In one embodiment, the first energy absorbing portion 401 and the second energy absorbing portion 402 may be equipped with a power source to drive the winding drums therein to release the first flexible member 410 and the second flexible member 420, while simultaneously applying force to the second end 305 of the boom 300. FIG9 does not illustrate the internal structure of the first energy absorbing portion 401 and the second energy absorbing portion 402; however, the energy absorbing portion 401 should be configured according to the description of the present disclosure.

[0068] In one embodiment, in order to achieve an all-round scan of the human body, the imaging assembly is designed to move along the support column 200, for example, up and down. As shown in FIG4 , in an embodiment of the present disclosure, the human body scanning device may include an imaging guide rail 202, which is arranged on one side of the support column 200. The first end portion 306 of the imaging assembly slides on the imaging guide rail 202 via an imaging sliding mechanism. The imaging sliding mechanism may be, for example, a general component such as a pulley or a slider, which allows the imaging assembly to slide stably on the imaging guide rail 202. The imaging guide rail 202 may be a guide rail that can be obtained by those skilled in the art. The imaging assembly is supported by the imaging guide rail 202 via the imaging sliding mechanism and moves along the imaging guide rail 202, thereby achieving smooth movement of the imaging assembly and being able to achieve smooth up and down movement of the imaging assembly with a relatively small driving force.

[0069] According to an embodiment of the present disclosure, as shown in Figure 4, a human body scanning device may include a pulley support assembly. The pulley support assembly includes: a support pulley 208-0 located at the top of the support column 200; a counterweight cable (not shown) surrounding the support pulley 208-0; and a counterweight box 204. One end of the counterweight cable is connected to the first end 306 of the boom 300, and the other end is connected to the counterweight box 204. This allows the weight of the imaging assembly to be balanced by the counterweight box 204.

[0070] According to an embodiment of the present disclosure, as shown in FIG10 , a human body scanning device may include a pulley support assembly. The pulley support assembly includes: a first support pulley 208-1 located at the top of the support column 200; a second support pulley 208-2 located at the top of the support column 200; a counterweight cable 205 surrounding the first and second support pulleys 208-1, 208-2; and a counterweight box 204. One end of the counterweight cable 205 is connected to the first end 306 of the boom 300, and the other end is connected to the counterweight box 204. This allows the weight of the imaging assembly to be balanced by the counterweight box 204. In this embodiment, unlike the embodiment shown in FIG4 , the first and second support pulleys 208-1, 208-2 are provided at the top of the support column 200, as well as a support boom 208. As shown in the figure, the first and second support pulleys 208-1, 208-2 are provided at the ends of the support boom 208 that extends forward (toward the first end 306 of the boom 300). Those skilled in the art may also provide other types or forms of pulley support assemblies as needed.

[0071] Since the counterweight box 204 is provided, the counterweight is allowed to balance the weight of the imaging assembly via the counterweight cable 205, so that the imaging assembly only needs a small driving force when moving up and down along the support column 200, and there is no need to provide a force equal to or greater than the weight of the imaging assembly to lift the imaging assembly.

[0072] In one embodiment, as shown in FIG4 , a human body scanning device may include a counterweight guide rail 203, along which a counterweight box 204 moves via a counterweight sliding mechanism. The counterweight box 204 moves along the counterweight guide rail 203, thereby limiting its movement trajectory. This prevents the counterweight box 204 from lateral movement or vibration, which would increase the load on the counterweight cable 205. This reduces vibration of the counterweight box 204 and improves its stability during movement, thereby minimizing the risk of vibration from the counterweight box 204 to the imaging assembly.

[0073] In an embodiment of the present disclosure, a human body scanning device may include a drive assembly. The drive assembly includes: a first drive pulley 206-1 located at the top of the support column 200; a second drive pulley 206-2 located at the bottom of the support column 200; a transmission toothed belt 206 surrounding the first and second drive pulleys 206-1, 206-2; and a motor 207 that drives the first or second drive pulley 206-1, 206-2. The imaging assembly is connected to the transmission toothed belt 206 so as to be driven up and down by the transmission toothed belt 206. When the motor 207 drives the first or second drive pulley 206-1, 206-2, the transmission toothed belt 206 is driven, thereby driving the imaging assembly connected to the transmission toothed belt 206 to move.

[0074] The drive assembly provides a pulley system consisting of first and second drive pulleys 206-2, which are independent of the support pulley system consisting of the first and second support pulleys. The imaging assembly is connected to a toothed drive belt 206 and a counterweight cable 205, so that the toothed drive belt 206 and the counterweight cable 205 move synchronously. The support pulley system supports the weight of the imaging assembly, balancing the weight of the imaging assembly. The pulley system of the drive assembly only needs to provide a small driving force to achieve the vertical movement of the imaging assembly. In this case, the motor is a servo motor, which is advantageous because it requires less force to be provided.

[0075] In an embodiment of the present disclosure, the human body scanning device may include an elastic tensioning device 330. As shown in Figures 9 and 10, the movable end 331 of the elastic tensioning device 330 abuts the conveyor toothed belt to allow the conveyor toothed belt to move while tensioning the conveyor toothed belt. The movable end 331 of the elastic tensioning device 330 may include a smooth surface, or a gear may be provided to engage with the conveyor toothed belt, allowing the conveyor toothed belt to move when the movable end 331 presses against the conveyor toothed belt. The elastic tensioning device 330 may be elastic in itself, so that the movable end 331 can be extended and retracted to allow elastic pressure to be applied to the conveyor toothed belt. For example, as shown in Figure 9, the movable end 331 of the elastic tensioning device 330 can be extended and retracted in the horizontal direction to provide thrust to the conveyor toothed belt. In another embodiment, the movable end 331 of the elastic tensioning device 330 can be rotated along one end of the elastic tensioning device 330 (the end mounted on the support column 200), so that the movable end 331 can adjust the force applied to the conveyor toothed belt, or keep pressing against the conveyor toothed belt, so that the conveyor toothed belt is in a tensioned state.

[0076] In an embodiment of the present disclosure, as shown in Figures 2 and 3, a body scanning device may include a base 100, with the support column 200 mounted on the base 100. Thus, the body scanning device comprises a single unit, with all components located on the base 100. By moving the base 100, the body scanning device can be moved as a whole. Due to the provision of the base 100, the body scanning device can be used in a variety of scenarios, adapting to different locations such as muddy fields, grasslands, airports, and train stations. The base 100 can be stably placed in various locations to perform body scanning inspections.

[0077] In an embodiment of the present disclosure, the base 100 includes a ground support 101 for statically supporting the base 100. The ground support 101 allows the base 100 to be supported by a limited support point on the ground; and the ground support 101 can adjust the height so that the base 100 stably supports a horizontal surface, overcoming the problem that the ground may be uneven. There can be four ground supports 101. For example, for a rectangular base 100, one ground support 101 is provided at each of the four corners. The four ground supports 101 can be adjusted separately or some of them can be adjusted separately, thereby raising or lowering the horizontal height of a corner of the base 100, and ultimately ensuring the stability of the base 100. For example, the upper surface of the base 100 can be located on a horizontal plane. However, the upper surface of the base 100 may not be horizontal. The base 100 only needs to remain stable to complete the human body scanning inspection.

[0078] In an embodiment of the present disclosure, as shown in FIG3 , the base 100 may include casters 102 configured to be retracted to the bottom of the base 100 and to be deployed to support the base 100, exceeding the height at which the base 100 is supported by the anchor support 101, and allowing the human body scanning device supported by the base 100 to slide freely. The casters 102 may be mounted on the lower surface of the base 100, which may include a groove 103. When the base 100 is stationary and placed on the ground, the casters 102 may be retracted and accommodated in the groove 103; the casters 102 may be deployed from the groove 103 to support the base 100. For example, for a rectangular base 100, grooves 103 can be respectively set at the four corners of the rectangle, and the casters 102 are respectively set in the grooves 103, for example, installed in the grooves 103. When the casters 102 are unfolded from the grooves 103, the casters 102 support the corners of the base 100, and when the casters 102 support the corners of the base 100, the anchor support 101 at the corners is suspended in the air. At this time, the base 100 is supported by the casters 102, thereby allowing the base 100 to move by rolling the casters 102.

[0079] Through the dual design of the anchor support 101 and the casters 102, the base 100 can stably support the human body scanning device to perform human body security inspections in a stationary and stable manner. At the same time, the base 100 can allow the human body scanning device to move freely, greatly improving the transfer movement of the human body scanning device.

[0080] In embodiments of the present disclosure, a body scanner device may include a housing 400 for housing the device and providing a surface for the user to stand on and space for inspection. As shown in Figure 1, the housing 400 encloses the components of the body scanner device, protecting the imaging assembly, base 100, pulley support assembly, and drive assembly from external damage and corrosion. The housing 400 provides a complete appearance and facilitates mobility; it also provides a standing position for the user, making it convenient for inspection.
