Description

Technical Field

[0001] The present invention relates to a control method for a light strip of a static CT, and also relates to a corresponding light strip control system, belonging to the technical field of medical devices. Background Art

[0002] Traditional CT systems mainly consist of components such as a gantry, a high-voltage generator, an X-ray tube, detectors, a power supply cabinet, and a scanning bed. Among them, the gantry is the carrier of the high-voltage generator, the X-ray tube, and the detectors, transmits electrical energy through a slip ring, and can rotate at high speed. However, the rotation of the gantry is restricted by the physical structure. The huge acceleration generated during high-speed rotation will not only affect the working performance of the components on the gantry, but may also cause safety problems. In addition, the rotation speed of the gantry has become a bottleneck restricting the improvement of the CT time resolution. Therefore, the next-generation revolutionary CT technology is considered to be static CT.

[0003] Static CT is defined as the sixth-generation CT, and its core components include a detector ring and a radiation source ring. Compared with traditional spiral CT, static CT adopts a double-ring structure composed of a radiation source ring and a detector ring, replacing the slip ring structure. This design makes the time resolution of CT equipment no longer dependent on the mechanical rotation speed. The detector ring consists of multiple photon stream detectors, and the radiation source ring consists of distributed X-ray tubes or array integrated radiation sources.

[0004] The whole machine working life cycle of static CT will experience a series of working states such as self-check, standby, parameter configuration, system preparation, system operation, and exposure control from power-on self-check to power-off. Due to the large number of components it contains, the system state is complex, and the state transition is also relatively complex. And the conventional CT control and display device cannot display the current system state and state transition situation in a timely and accurate manner, which is not conducive to the operator to understand the whole machine system state. Therefore, it is urgent to propose a solution that can display the state of static CT to solve the above problems. Summary of the Invention

[0045] The technical content of the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0046] In the embodiment of the present invention, by controlling the light strip to switch between different lighting modes, the current system state of the static CT can be displayed in a timely and accurate manner, so as to help medical staff more intuitively understand the CT scan situation, so that they can react in time when the CT scan goes wrong and avoid harm to patients.

[0047] The First Embodiment

[0048] AsFigure 1 and Figure 2 As shown in Figure 2 , a method for controlling a light strip for static CT provided by an embodiment of the present invention specifically includes the following steps:

[0049] S1: Obtain the scanning parameters issued by the host computer.

[0050] In this embodiment, the host computer is the host system for human-computer interaction of the static CT, which can perform human-computer interaction with the user (usually a doctor), so as to obtain the data information input by the doctor (for example: disease type, CT scan dose, patient personal information, etc.), and then form corresponding scanning parameters according to the data information.

[0051] S2: Based on the scanning parameters, obtain the working mode of the static CT.

[0052] It can be understood that there are multiple radiation sources on the radiation source ring of the static CT, generally 24 (not limited to this number). For patients with different disease types, different ages, and different heights and weights, the number and positions of the radiation sources required for CT scanning are different.

[0053] Therefore, after obtaining the scanning parameters of the patient based on step S1, it can be determined which radiation sources need to work and which radiation sources need to standby according to the scanning parameters, so as to form a specific working mode according to the scanning parameters. It can be understood that for the static CT, in different working modes, multiple radiation sources in different regions are in the working state, and the remaining radiation sources are in the standby state.

[0054] For example: number the 24 radiation sources on the radiation source ring from 1 to 24. For patient A, 8 consecutive radiation sources from 1 to 8 are required for CT scanning; however, for patient B, a total of 12 radiation sources, namely 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23, are required for CT scanning.

[0055] S3: Detect whether each radiation source in the working state is normal.

[0056] Specifically, when it is determined which radiation sources need to work and which radiation sources need to standby through step S2, it is necessary to detect each radiation source in the working state to ensure that the CT scanning can be carried out normally.

[0057] Among them, the detection of the radiation source can include the following contents:

[0058] (1) Radiation source intensity detection

[0059] It is understandable that as the ray source is continuously used, the radioactive particles may decay, resulting in a decrease in the radiation dose of the X-ray. Therefore, before performing a CT scan, it is necessary to first detect whether the scanning dose of each ray source is at a normal level to ensure that it is within the specified range and meets the imaging requirements.

[0060] (2) Ray source focus detection

[0061] If the focus of the ray source is offset, it will affect the final scanning result. Therefore, before performing a CT scan, it is necessary to confirm that the focus of each ray source is in the correct position or within the allowable offset error to ensure the clarity and resolution of the imaging.

[0062] (3) Ray source stability detection

[0063] Under long-term continuous exposure, detect the stability of the ray source, including the fluctuation range of the radiation intensity, the stability of the focus position, etc. This helps to ensure that the imaging quality remains consistent during long-term scanning.

[0064] (4) Ray source safety detection

[0065] Detect whether the protective measures of the ray source are perfect, such as lead shielding, radiation dose monitoring, etc., to ensure that the ray source will not cause radiation damage to operators and patients under normal working conditions.

[0066] It should be noted that the above detection content is only for illustrative purposes, and in other embodiments, it can be adaptively adjusted according to requirements.

[0067] S4: Control the light strip according to different working modes.

[0068] Specifically, according to the detection results of step S3, the static CT system will enter one of the three working modes. In this embodiment, the static CT system includes a normal working mode (corresponding to step S41), an abnormal working mode (corresponding to step S42), and a shutdown mode (corresponding to step S43). It should be understood that the working mode here is for the static CT, aiming to show in which situation the static CT is working.

[0069] Next, a detailed description of how to control the light strip in the three working modes of the static CT system will be given:

[0070] S41: Normal working mode

[0071] When all the ray sources in the working state are normal, enter the normal working mode to control the light strip to switch between different lighting modes, thereby indicating the working state of the static CT.

[0072] Specifically, it includes steps S411 to S413:

[0073] S411: Control the first lighting parameter of the light strip to indicate the scanning dose of the static CT.

[0074] In an embodiment of the present invention, the first lighting parameter at least includes one or a combination of more of the following: the number of lit lights, the color of the lit lights, and the brightness of the lamp beads. The scanning dose of the static CT is indicated by the number of lit lights. The more the number of lit lights, the greater the scanning dose of the static CT. Specifically, each ray source corresponds to one lamp bead or a group of lamp beads on the light strip, so as to indicate the number of ray sources in the current working state by controlling the number of lit lamp beads or the number of lit lamp bead groups.

[0075] In another embodiment, the scanning dose of the static CT is indicated by the color of the lit lights. Different colors of the lit lights represent different scanning doses. For example, seven levels of scanning doses can be represented by red, orange, yellow, green, cyan, blue, and purple. When the light is red, it indicates the lowest scanning dose, and when the light is purple, it indicates the highest scanning dose. It can be understood that the specific correspondence between the color and the scanning dose can be determined according to needs and is not specifically limited here, as long as different colors correspond to different scanning doses.

[0076] In yet another embodiment, the scanning dose of the static CT is indicated by the brightness of the lamp beads. The brighter the brightness of the lamp beads, the greater the scanning dose of the static CT. Among them, the brightness of the lamp beads can be achieved by controlling the voltage.

[0077] In addition, in other embodiments, various combination methods such as the number of lit lights + the color of the lit lights, the number of lit lights + the brightness of the lamp beads, the color of the lit lights + the brightness of the lamp beads, and the number of lit lights + the color of the lit lights + the brightness of the lamp beads can also be used to indicate the scanning dose of the static CT, and specific adaptive selections can be made according to needs and are not detailed here.

[0078] It can be understood that for doctors, they can know in advance the required scanning dose before performing a CT scan on a patient. During the actual scanning process, by controlling the first lighting parameter of the light strip, doctors can be very intuitively prompted, so that doctors can easily observe the current CT scanning dose even when dealing with other things, and thus can take remedial measures in time when there are problems with the scanning dose (for example, the scanning dose changes due to misoperation).

[0079] S412: Control the second lighting parameter of the light strip to indicate the scanning area of the static CT.

[0080] In this embodiment, the second lighting parameter at least includes the lighting area. The light strip is pre-divided into multiple lighting areas, and each lighting area corresponds to a different scanning area of the static CT; moreover, preselected lamp beads are provided in each lighting area. For example: the light strip is divided into 6 lighting areas, namely upper, lower, upper left, lower left, upper right, and lower right, with each interval being 60°, so as to correspond to 6 different scanning areas.

[0081] Specifically, when the ray sources in the working state are concentrated in the same scanning area, the corresponding lighting area on the light strip is controlled to emit light. For example: when CT scanning is required using ray sources 1 to 3, only the lighting area located above needs to be lit.

[0082] When the ray sources in the working state are in multiple scattered scanning areas, the preselected lamp beads in the corresponding multiple lighting areas on the light strip are controlled to emit light. For example: when CT scanning is required using ray sources 1, 6, and 11, the three ray sources are respectively in the upper, lower left, and lower right scanning areas, so it is necessary to control the preselected lamp beads in the upper, lower left, and lower right lighting areas to emit light, thereby indicating the scanning area of the static CT.

[0083] It can be understood that for doctors, they can know in advance the part to be scanned before performing CT scanning on patients. During the actual scanning process, by controlling the second lighting parameter of the light strip, doctors can be very intuitively prompted, so that doctors can easily observe the current CT scanning part even when dealing with other things, and thus can take remedial measures in time when problems occur in the scanning area (for example: the scanning area changes due to misoperation).

[0084] S413: Control the third lighting parameter of the light strip to indicate the exposure state of the static CT.

[0085] In an embodiment of the present invention, the third lighting parameter at least includes one or a combination of more of lighting color, lamp bead brightness, and flashing change. Moreover, the exposure state at least includes three stages: starting exposure, in-exposure, and exposure end, and the exposure state in each stage corresponds to different third lighting parameters.

[0086] When the exposure state is starting exposure, the display effect of the light strip is white, and its brightness changes with time, showing a breathing lamp effect. When the exposure state is in-exposure, the display effect of the light strip is that one-third of the light strip is green, and its position keeps changing, showing a partial green lamp bead rotation effect. When the exposure state is exposure end, the display effect of the light strip is that the entire light strip is constantly blue.

[0087] It can be understood that in other embodiments, the light strip can be controlled to achieve different display effects (quantity, color, brightness, etc.) so that the scanning exposure form of the static CT is represented by the light strip, thereby prompting the current exposure state of the static CT to medical staff. Moreover, for doctors, they can generally understand what exposure state should be in at what time period, and thus, by controlling the third lighting parameter of the light strip, directly indicate the exposure state of the static CT to doctors, and then be able to take remedial measures in time when there are problems with the exposure state of the static CT.

[0088] In this embodiment, in the normal working mode, the scanning dose, scanning area, and exposure state of the static CT are respectively indicated through steps S411 - S413, thus jointly constituting the working state of the static CT.

[0089] It can be understood that in another embodiment, the working state of the static CT can also be represented only by the scanning dose and / or scanning area.

[0090] S42: Abnormal working mode

[0091] If there are abnormalities in each ray source in the working state and the abnormal data is less than the preset threshold, then enter the abnormal working mode to control the light strip to switch between different lighting modes, thereby indicating the current system state of the static CT; and control the light strip to emit a first warning message.

[0092] In this embodiment, in the abnormal working mode, since the abnormal data is less than the preset threshold, therefore, it will not have a great impact on the overall CT scan, and the CT scan of the patient can continue to avoid wasting resources due to restarting the device. At this time, the light strip will be normally displayed according to the mode in step S41. And on this basis, the light strip will also emit a first warning message to prompt the doctor that although the current CT scan can be carried out, there are abnormal situations that need to be processed after the CT scan is completed.

[0093] The process of the normal display of the light strip in step S42 is the same as that in the above step S41 and will not be elaborated here. The difference from step S41 is that on the basis of normal display, the emission color of the warning light on the light strip is also controlled (for example: yellow light), thereby using this warning light to alert medical staff.

[0094] In addition, it can be understood that setting the warning light and controlling the color of the warning light to emit the first warning message is only one implementation method. In other embodiments, it can be adaptively adjusted according to needs as long as it can play a warning role.

[0095] S43: Shutdown mode

[0096] If there are abnormalities in the individual radiation sources in the working state and the abnormal data is greater than the preset threshold, the system enters the shutdown mode and controls the light strip to emit a second warning message.

[0097] It can be understood that when the abnormal data is greater than the preset threshold, it means that CT scanning can no longer be performed and shutdown maintenance is required. At this time, the warning light of the light strip is controlled to turn red (or the light beads of the light strip itself can be controlled to turn red) to emit the second warning message. In addition, a buzzer can be used for sound warning.

[0098] Second Embodiment

[0099] As Figure 2 shown, a light strip control system for a static CT provided by the second embodiment of the present invention includes a host computer 1, a calculation module 2, a detection module 3, a central control module 4, and a light strip control module 5.

[0100] Among them, the host computer 1 is the main system for human-computer interaction of the static CT and can perform human-computer interaction with the user (usually a doctor). The calculation module 2 is communicatively connected to the host computer through the system bus, thereby receiving the scanning parameters sent by the host computer 1, calculating the data according to the scanning parameters, determining which radiation sources need to work and which radiation sources need to standby, and finally determining the working mode of the static CT.

[0101] The detection module 3 is communicatively connected to the calculation module 2 through the system bus to detect whether each radiation source in the working state is normal. Among them, the specific method of using the detection module 3 for system detection can be adaptively set according to needs (for example: detecting parameters such as radiation source intensity, focus, etc.), and no specific limitation is made here.

[0102] The central control module 4 is connected to the detection module 3 through the system bus. After the detection module 3 completes the detection, it sends the detection result to the central control module 4. The central control module 4 generates different control instructions according to different detection results and sends them to the light strip control module 5.

[0103] Correspondingly, the light strip control module 5 is connected to the central control module 4 through the system bus, thereby receiving the control instructions sent by the central control module and controlling the light strip to execute the control instructions.

[0104] It can be understood that when the detection result of the detection module 3 is normal, the light strip executes the control instructions, thereby switching between different lighting modes to indicate the current system state of the static CT.

[0105] When the detection result of the detection module 3 is abnormal and the abnormal data is less than the preset threshold, the light strip executes the control instruction, thereby switching between different lighting modes to indicate the current system state of the static CT. Moreover, a first warning message is also issued based on the control instruction (for example: controlling the warning light to turn yellow).

[0106] When the detection result of the detection module 3 is abnormal and the abnormal data is greater than the preset threshold, the light strip executes the control instruction and issues a second warning message (for example: controlling the warning light to turn red) to prompt medical staff that the current static CT system has a fault and CT scanning cannot be performed.

[0107] In addition, it can be understood that the above functional modules are only module units corresponding to the respective steps in the above first embodiment, but are not limited to this functional form. In other embodiments, the respective functional modules can also be adjusted to implement the respective steps in the above first embodiment.

[0110] Among them, the processor 21 is used to control the overall operation of the light strip control system to complete all or part of the steps of the above light strip control method for static CT.

These data can include, for example, instructions for any application program or method operating on the light strip control system, as well as application program related data. The memory 22 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read only memory (EEPROM), erasable programmable read only memory (EPROM), programmable read only memory (PROM), read only memory (ROM), magnetic memory, flash memory, etc.

[0111] In an exemplary embodiment, the light strip control system may be specifically implemented by a computer chip or an entity, or by a product with certain functions, and is used to execute the above-mentioned light strip control method for static CT and achieve the same technical effects as the above method. Specifically, the computer may be, for example, a personal computer, a laptop computer, an in-vehicle human-machine interaction device, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

[0112] In another exemplary embodiment, the present invention also provides a computer-readable storage medium including program instructions, and when the program instructions are executed by a processor, the steps of the light strip control method for static CT in any of the above embodiments are implemented. For example, the computer-readable storage medium may be the above-mentioned memory including program instructions, and the above program instructions can be executed by the processor of the light strip control system to complete the above-mentioned light strip control method for static CT and achieve the same technical effects as the above method.

[0113] In summary, a light strip control method and system for static CT provided by the embodiments of the present invention have the following beneficial effects:

[0114] (1) By controlling the light strip to switch between different lighting modes, the current system state of the static CT can be intuitively indicated to prompt medical staff and avoid affecting normal CT scans due to misoperation.

[0115] (2) It can perform personalized light strip display according to the detection results of the radiation source, thereby indicating the working mode of the static CT to medical staff, so that different operation means can be adopted according to different working modes.

[0117] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.
