Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical scanning, in particular to a medical image scanning system and a positioning method thereof. BACKGROUND

[0002] Before a patient is subjected to a medical image scanning, a medical image scanning system needs to be positioned, i.e. a scanning bed in the medical image scanning system is moved to a proper scanning starting position so as to obtain an image of a desired scanning part. Currently, there are two ways to position the medical scanning system. One way is that a user enters a shielded room and controls the scanning bed to move to the proper scanning starting position through a laser lamp and buttons on a scanning device. The other way is that a user sets a scanning starting position corresponding to a typical scanning part and scanning posture by using a function button on a gantry.

[0003] The above two ways require the user to enter the shielded room to operate each time, which causes the user to be unnecessarily radiated by scattered rays. Although the second way can simplify the user operation, due to the limitation of hardware, it is impossible to set a corresponding function button on the scanning device for each scanning part and scanning posture. Generally, only the scanning starting positions of commonly used scanning parts, such as the head and the chest, are set. When it comes to uncommon scanning parts and scanning postures, the user still needs to enter the shielded room to operate. SUMMARY

[0004] Therefore, it is necessary to provide a medical image scanning system and a positioning method thereof, which can improve the safety and convenience of the medical image scanning system positioning.

[0005] A medical image scanning system, comprising:

[0006] a scanning device located in a shielded room, the scanning device having a scanning cavity;

[0007] a scanning bed located in the shielded room, the scanning bed moving along the scanning cavity; and

The scanning control device has a storage module in which an association between the scanning site and the scanning body position and the scanning starting position is stored. Therefore, a user can use the scanning control device outside the shielding room to complete the positioning of the medical image scanning system, without entering the shielding room every time, thereby avoiding radiation of the user, saving the workload of the user, simplifying the positioning process of the medical image scanning system, improving the convenience and safety of the positioning of the medical image scanning system, and reducing the hardware cost of the medical image scanning system.

[0010] In one of the embodiments, the scanning control device comprises:

[0031] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0032] The embodiments of the present application will be described in detail below with reference to the drawings.

[0033] In one embodiment, Figure 1 A structural schematic diagram of a medical image scanning system is shown, which includes a scanning device 100 located in a shielding room, a scanning bed 200 located in the shielding room, and a scanning control device 300 located outside the shielding room. The scanning device 100 has a scanning cavity 101, and the scanning bed 200 moves along the scanning cavity 101 during scanning. As shown, Figure 2 The scanning control device 300 includes a storage module 301 for storing the association relationship between the scanning site and the scanning body position of the scanning target and the scanning starting position of the scanning bed 200. The scanning control device 300 is used to adaptively match the scanning starting position of the scanning bed 200 according to the scanning site and the scanning body position of the scanning target.

[0034] The medical image scanning system includes, but is not limited to, CT scanning, MR scanning, SPECT scanning, or PET scanning, and other common medical image scanning systems.

[0035] The shielding room is a scanning room for medical image scanning of the scanning target, and can prevent the leakage of rays inside the room to the outside.

[0036] Before using the medical image scanning system for scanning, the user needs to input each scanning site and each scanning body position, and the scanning starting position associated with these scanning sites and these scanning body positions. Specifically, the user inputs each scanning site and each scanning body position on the scanning control device 300, and adjusts the scanning bed 200 to the scanning starting position associated with the scanning site and the scanning body position. The scanning control device 300 acquires the scanning starting position, and the storage module 301 stores the scanning site, the scanning body position and the scanning starting position in association, so that in subsequent positioning of the medical image scanning system, the corresponding scanning starting position can be directly obtained from the storage module 301.

[0037] The user can adjust the scanning bed 200 to the scanning starting position associated with the scanning site and the scanning body position according to his own experience or the experience of experts in the field of medical image scanning.

[0038] The scanning site can be the head, chest, abdomen, or other parts, and the scanning body position is the body position of the patient lying on the scanning bed 200.

[0039] As an example, the scanning position in which the patient lies flat on the scanning bed, in a supine position with the head facing the inside of the CT scanning device is referred to as the HFS (Head First-Supine) position; the scanning position in which the patient lies flat on the scanning bed, in a prone position with the head facing the inside of the CT scanning device is referred to as the HFP (Head First-Prone) position; the corresponding scanning positions in which the feet face the inside of the CT scanning device are the FFS (Feet First-Supine) position and FFP (Feet First-Prone) position respectively.

[0040] For example, depending on whether the patient is lying on the left or right side, and whether the head is facing the inside of the CT scanning device or the feet are facing the inside of the CT scanning device, the scanning position is divided into HFDL (Head First-Decubitus Left), FFDL (Feet First-Decubitus Left), HFDR (Head First-Decubitus Right) and FFDR (Feet First-Decubitus Right).

[0041] When using a medical imaging scanning system for scanning, the user needs to position the system. Specifically, the user enters the scanning area and scanning position on the scanning control device 300. The scanning control device 300 retrieves the scanning starting position associated with the scanning area and scanning position from the storage module 301. The scanning control device 300 sends the scanning starting position associated with the scanning area and scanning position to the scanning device 100. The scanning device 100 adjusts the bed code of the scanning bed 200 at the start of scanning based on the scanning starting position, thereby completing the positioning of the medical imaging scanning system. The scanning starting position is the bed code of the scanning bed 200 at the start of scanning. The scanning bed 200 will move along the scanning cavity 101 from the scanning starting position.

[0042] In one embodiment, Figure 2 As shown, the scanning control device 300 further includes a processor 302 connected to the storage module 301. The processor 302 is provided with a data query module for querying the storage module 301 for a scanning starting position associated with the scanning part and scanning body position input by the user.

[0043] In one embodiment, Figure 3As shown, the scanning control device 300 further comprises a display screen 303, which is used to provide a user interaction interface, on which the user inputted scanning sites and scanning positions are received and displayed so that the user can know the content inputted by himself. Further, when scanning using the medical image scanning system, the scanning sites and scanning positions are displayed on the user interaction interface, prompting the user to select the scanning site and scanning position for current scanning from them, so as to complete the input of the scanning site and scanning position. The user can also input a keyword on the user interaction interface, and the data query module in the processor 302 queries the scanning sites and scanning positions containing the keyword or matching the keyword beyond a preset threshold in the storage module 301, and outputs these queried scanning sites and scanning positions on the user interaction interface for the user to select. In addition, the user can also directly input the scanning site and scanning position for current scanning on the user interaction interface, and the user interaction interface has an editing function.

[0044] The display screen 303 can be connected with the processor 302, and the processor 302 obtains the scanning sites and scanning positions needed to be displayed from the storage module 301 and sends them to the display screen 303. In addition, the storage module 301 can also directly send the stored scanning sites and scanning positions to the display screen 303 for display.

[0045] In one embodiment, after adjusting the scanning bed 200 to the scanning starting position, the camera on the scanning device 100 obtains the positioning image containing the scanning bed 200 in the scanning cavity 101 and sends it to the scanning control device 300, and the scanning control device 300 outputs the positioning image of the scanning bed 200 on the display screen 304, so that the user can intuitively observe from the positioning image whether the medical image scanning system is positioned accurately, thereby improving the positioning accuracy and user experience of the medical image scanning system.

[0046] In one embodiment, as shown in Figure 4 and Figure 5 The scanning control device 300 further comprises a control box 304, which can be an independent device in the scanning control device 300 or a control module in the scanning control device 300.

[0047] In one embodiment, when the control box 304 is an independent device in the scanning control device 300, the scanning control device 300 comprises the control box 304 and a computer device, the control box 304 is connected to the computer device by a hardware connection mode (for example, a USB connection mode, a WiFi connection mode), the storage module 301 on the scanning control device 300 can be located on the controller 304 or on the computer device, and the storage module 301 located on the computer device is more conducive to copying and backing up the association relationship between the scanning site and the scanning body position and the scanning starting position. In addition, the display screen 303 on the scanning control device 300 can comprise a display screen on the controller 304 and a display screen on the computer device, or can only be a display screen on the computer device.

[0048] In one embodiment, when the control box 304 is a control module in the scanning control device 300, the scanning control device 300 is an integral computer device, and the control box 304 is a virtual control box on the computer device, and the control box 304 can be connected to the processor 302.

[0049] In one embodiment, the control box 304 is provided with a voice collection module, when a user needs to input a scanning site and a scanning body position into the storage module 301, or when the user needs to perform a medical image scanning system positioning, voice input can be performed on the control box 304, and the voice of the user is collected by the voice collection device in the control box 304, so as to improve the convenience of inputting the scanning site and the scanning body position. As an example, a voice collection button can be provided on the control box 304, and the user can perform voice input by pressing the button.

[0050] In one embodiment, the scanning control device 300 is provided with a voice recognition module, and the voice recognition module is used to recognize a scanning site and a scanning body position from the voice of the user collected by the voice collection device. When in the input stage of the scanning site and the scanning body position, the recognized scanning site and scanning body position are sent to the storage module 301 for storage, and when in the medical image scanning system positioning stage, the recognized scanning site and scanning body position are sent to the data query module on the processor 302, and the data query module queries the associated scanning starting position from the storage module 301.

[0051] In one embodiment, the voice recognition module is located on the control box 304 or on the processor 302 of the scanning control device 300. When the voice recognition module is located on the control box 304, the collection and recognition of the voice of the user are completed by the control box 304. When the voice recognition module is located on the processor 302, the control box 304 sends the collected voice of the user to the processor 302, and the voice recognition module on the processor 302 performs voice recognition.

[0052] Specifically, the scanning site keyword set and the scanning body position keyword set are pre-built in the voice recognition module. When the user's voice is recognized, the scanning site keyword set is matched with the text content corresponding to the user's voice to obtain the scanning site in the user's voice, and the scanning body position keyword set is matched with the text content corresponding to the user's voice to obtain the scanning body position in the user's voice, thereby improving the accuracy of scanning site and scanning body position recognition.

[0053] In one embodiment, after the scanning bed 200 is adjusted to the scanning starting position, the user needs to fine-tune the scanning starting position according to the body type of the scanning target due to the different body types of different patients. The control box 304 is provided with a fine-tuning module. When the control box 304 receives the fine-tuning request of the user, the fine-tuning direction command and the fine-tuning distance command of the scanning bed input by the user are obtained through the fine-tuning module, and the fine-tuning direction command and the fine-tuning distance command of the scanning bed are sent to the scanning device 100. The scanning bed 200 is controlled by the scanning device 100 to fine-tune the position, thereby further improving the positioning accuracy of the medical image scanning system.

[0054] In one embodiment, the connection mode between the scanning control device 300 and the scanning device 100 is wired connection. The scanning control device 300 sends the scanning starting position to the scanning device 100 in a wired manner, avoiding interference with the scanning environment in a wireless communication mode, and ultimately affecting the scanning effect.

[0055] The above medical image scanning system comprises a scanning device 100 located in a shielding room, a scanning bed 200 located in the shielding room, and a scanning control device 300 located outside the shielding room. The scanning device has a scanning cavity 101. The scanning bed 200 moves along the scanning cavity 101. The scanning control device 300 is connected with the scanning device 100, and is used to adaptively match the scanning starting position of the scanning bed 200 according to the scanning site and the scanning body position. The storage module 301 in the scanning control device 300 stores the association relationship between the scanning site and the scanning body position and the scanning starting position. Therefore, the user can use the scanning control device 300 outside the shielding room to complete the positioning of the medical image scanning system, without entering the shielding room for positioning each time, thereby avoiding radiation of the user, saving the workload of the user, simplifying the positioning process of the medical image scanning system, and improving the convenience and safety of the positioning of the medical image scanning system. In addition, the medical image scanning system does not need to be provided with function buttons corresponding to the scanning site and the scanning body position, thereby reducing the hardware cost of the medical image scanning system.

[0056] In one embodiment, as shown in Figure 6 a positioning method of a medical image scanning system is provided, comprising the following steps:

[0057] Step 602, when receiving the user's positioning request, the current scanning site and scanning position are obtained by scanning control device.

[0058] Specifically, before performing medical image scanning, the user can send a positioning request to the medical image scanning system, and when receiving the positioning request, the current scanning site and scanning position are obtained by the scanning control device to achieve the positioning of the medical image scanning system, i.e. moving the scanning bed in the medical image scanning system to the appropriate scanning starting position. Wherein, the user can input the current patient's scanning site and scanning position on the scanning control device.

[0059] Wherein, the medical image scanning system includes a scanning control device, a scanning device and a scanning bed located in the scanning cavity of the scanning device, the scanning device and the scanning bed are located in the shielding room, and the scanning control device is located outside the shielding room. The specific structure of the medical image scanning system has been described in detail in the above embodiment, which will not be repeated here.

[0060] In one embodiment, a user interaction interface is provided on the display screen of the scanning control device, and the scanning site and scanning position input by the user are received and displayed on the user interaction interface, so that the user can understand the content input by himself. Further, when using the medical image scanning system to perform scanning, the scanning sites and scanning positions stored in the scanning control device are displayed on the user interaction interface, reminding the user to select the scanning site and scanning position of the current scanning from them, and complete the input of the scanning site and scanning position. The user can also input a keyword on the user interaction interface, query the scanning sites and scanning positions containing the keyword or matching the keyword beyond a preset threshold from the scanning sites and scanning positions stored in the scanning control device, and output these queried scanning sites and scanning positions on the user interaction interface for the user to select. In addition, the user can also directly input the scanning site and scanning position of the current scanning on the user interaction interface, and the user interaction interface has an editing function.

[0061] In one embodiment, when entering the association relationship between each scanning site and scanning position and the scanning starting position in the scanning control device, the user inputs each scanning site and scanning position on the scanning control device, and adjusts the scanning bed to the scanning starting position associated with the scanning site and scanning position according to his own experience or the experience of experts in the field of medical image scanning. The scanning starting position is obtained by the scanning control device, and the scanning site and scanning position input by the user are obtained, and the scanning site, scanning position and scanning starting position are stored in association, so that in subsequent positioning of the medical image scanning system, the scanning starting position associated with the scanning site and scanning position can be directly queried from the scanning control device.

[0062] In one embodiment, the scanning control device comprises a controller, which is a separate hardware device in the scanning control device or a virtual controller in the scanning control device. The controller collects the user voice, identifies the collected user voice, and obtains the scanning site and the scanning body position in the user voice. When the controller is a separate hardware device in the scanning control device, the association between the scanning site, the scanning body position, and the scanning starting position can be stored in the controller or a computer device connected to the controller in the scanning control device. In addition, the user voice can be identified in the controller or the computer device.

[0063] Specifically, a scanning site keyword set and a scanning body position keyword set are constructed in advance. When identifying the user voice, the scanning site keyword set is matched with the text content corresponding to the user voice to obtain the scanning site in the user voice, and the scanning body position keyword set is matched with the text content corresponding to the user voice to obtain the scanning body position in the user voice, thereby improving the accuracy of the scanning site and the scanning body position identification.

[0064] In step 604, the scanning control device queries the scanning starting position associated with the scanning site and the scanning body position. The scanning control device pre-stores the association between the scanning site, the scanning body position, and the scanning starting position.

[0065] Specifically, when the user inputs the scanning site and the scanning body position of the current scan, the scanning control device queries the scanning starting position associated with the scanning site and the scanning body position of the current scan in the association between the scanning site and the scanning body position stored in the scanning control device and the scanning starting position.

[0066] In step 606, the scanning starting position is sent to the scanning device, and the scanning device controls the scanning bed to move to the scanning starting position.

[0067] Specifically, the scanning control device sends the queried scanning starting position to the scanning device, the scanning device controls the scanning bed to move to the scanning starting position, and the current positioning of the medical image scanning system is completed.

[0068] In one embodiment, after the scanning bed is adjusted to the scanning starting position, the user needs to fine-tune the scanning starting position according to the body type of the scanning target because the body types of different patients are different. A fine-tuning module is arranged on the control box. When the control box receives the fine-tuning request of the user, the fine-tuning module obtains the scanning bed fine-tuning direction command and the scanning bed fine-tuning distance command input by the user, and sends the scanning bed fine-tuning direction command and the scanning bed fine-tuning distance command to the scanning device. The scanning device controls the scanning bed to fine-tune the position, thereby further improving the positioning accuracy of the medical image scanning system.

[0069] In one embodiment, after the positioning of the medical image scanning system is completed, a positioning image of the scanning bed in the scanning cavity is collected by a camera on the scanning device, the positioning image is sent to the scanning control device, and the positioning image of the scanning bed is output on the display screen of the scanning control device, so that the user can intuitively observe from the positioning image whether the positioning of the medical image scanning system is accurate, thereby improving the positioning accuracy and user experience of the medical image scanning system.

[0070] The positioning method of the medical image scanning system described above pre-stores the association relationship between each scanning site and each scanning body position and the scanning start position in the scanning control device, queries the scanning start position associated with the scanning site and the scanning body position when receiving the scanning site and the scanning body position input by the user, and sends the scanning start position to the scanning device, so that the user can complete the positioning of the medical image scanning system using the scanning control device outside the shield room, without entering the shield room for positioning each time, thereby avoiding radiation to the user, saving the workload of the user and simplifying the positioning process of the medical image scanning system, improving the convenience and safety of the positioning of the medical image scanning system, and in addition, without the need to set function buttons corresponding to the scanning site and the scanning body position on the medical image scanning system, the hardware cost of the medical image scanning system is reduced.

[0071] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.

[0072] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the scope of the present application.
