Since most scanning components in the system that depend on gradient parameters have already started, if the gradient coil is replaced, the system needs to be forcibly restarted and the gradient parameters of the currently connected gradient coil need to be refreshed, which increases the system startup time.

The devices in the magnetic resonance scanning system can be interconnected or communicate with each other via a network 130.

[0038] The scanning device 110 can scan an object. The object can be an animal, a physical object, a human body, an organ, tissue, etc. The scanning device can be a medical imaging device. In one embodiment, the scanning device 110 can be a magnetic resonance imaging (MRI) system, or a combination of an MRI system and other modal imaging devices (e.g., computed tomography (CT), positron emission tomography (PET), b-scan ultrasonography, thermal texture maps (TTM), medical electronic endoscope (MEE), etc.), such as a PET-MRI scanner. The scanning device 110 can generate image data corresponding to the object after scanning. Further, the scanning device 110 can send the acquired image data via network 130 to a scanning control device 120, a storage device 140, or a display device 150.

[0039] The scanning control device 120 can control the scanning process. For example, based on the target gradient coil connected to the magnetic resonance device, it determines the corresponding target gradient coil type, and based on the target gradient coil type, controls the scanning component in the magnetic resonance device to load the corresponding target gradient parameters and start it, controlling the magnetic resonance device to perform scanning using the target gradient parameters.

[0043] Figure 2 This is a flowchart of a magnetic resonance scanning control method according to an embodiment of the present invention. In one embodiment, the process can be implemented by a scanning control device 120. In one embodiment, such as Figure 2 As shown, a magnetic resonance scanning control method is proposed, including the following steps:

[0044] S201: Determine the type of target gradient coil based on the target gradient coil connected to the magnetic resonance device.

[0045] The gradient coils that can be connected to the magnetic resonance equipment can be divided into various types based on their performance, such as high-performance thick gradient coils and ordinary-performance thin gradient coils. Of course, gradient coils with different performance requirements and different thicknesses can also be produced according to actual usage needs. In this embodiment, the type of gradient coil is not specifically limited.

[0046] Optionally, when a user replaces the gradient coil of the magnetic resonance imaging (MRI) device, the MRI device can obtain the target gradient coil type of the currently connected gradient coil by scanning the identification information on the gradient coil. This identification information can be a QR code, barcode, etc., and may include the gradient coil's code or unique ID, or the coil type. Optionally, the target gradient coil type can also be obtained by obtaining the user-inputted target gradient coil type, or the MRI device can automatically detect or identify whether a target gradient coil is currently connected. If a target gradient coil is confirmed to be connected, the target gradient coil type can be further determined. For example, the target gradient coil type can be determined by detecting relevant parameters of the MRI device or its internal detection circuit after the gradient coil is connected, such as current, voltage, and resistance. Based on the relationship between the magnitude of these parameters and the reference magnitudes of these parameters for different coil types, the target gradient coil type can be determined. It should be noted that the above methods for determining the target gradient coil type of the currently connected gradient coil are merely illustrative examples, and the methods for determining the target gradient coil type in this application embodiment are not limited.

[0047] S202: Based on the target gradient coil type, the scanning component in the magnetic resonance device is controlled to load the corresponding target gradient parameters and then started.

[0048] The target gradient parameters include the relevant physical parameters of the target gradient coil, such as the magnitude of the eddy current generated by the target gradient coil, the maximum field strength, the rate of ascent, the aperture size, and the configuration of the shimming coil.

[0049] Given that in existing technologies, the scanning component is often started first and then the target gradient parameters are loaded, if the gradient coil is changed, it is necessary to restart and refresh the gradient parameters of the currently connected gradient coil.

[0050] In this embodiment, the scanning component in the magnetic resonance device is started after loading the corresponding target gradient parameters based on the target gradient coil type. By controlling the timing of the scanning component and loading the target gradient parameters, the system's secondary startup is avoided, and the system startup time is reduced.

[0051] S203: Control the magnetic resonance device to scan using the target gradient parameters.

[0052] After the scanning component loads the corresponding target gradient parameters and starts, the magnetic resonance device is controlled to perform scanning using the target gradient parameters.

[0053] Based on steps S201-S203 above, the target gradient coil type is determined according to the target gradient coil connected to the magnetic resonance imaging (MRI) device. Based on the target gradient coil type, the scanning component in the MRI device is started after loading the corresponding target gradient parameters, and the MRI device is controlled to perform scanning using the target gradient parameters. By controlling the timing of the scanning component and loading the target gradient parameters, secondary system startup is avoided, reducing system startup time.

[0054] In one embodiment, such as Figure 3 As shown, based on the target gradient coil type, the scanning component in the magnetic resonance imaging device is controlled to load the corresponding target gradient parameters and then start, including:

[0055] S301: Determine whether the target gradient coil type is the same as the current gradient coil type corresponding to the current gradient parameter being loaded;

[0056] S302: Under different circumstances, control the scanning component to load the target gradient parameters and then start; under the same circumstances, control the scanning component to start.

[0057] The scanning component is located within the scanning device, which uses it to acquire image data. For example, the scanning component could be a pulse sequence translation subsystem. During image sequence scanning, it sets parameters such as the ramp rate and field strength in the gradient parameters to the gradient power amplifier, and then issues commands.

[0058] After the target gradient coil is connected to the magnetic resonance equipment, it cannot be determined whether the target gradient coil is the same as the previously connected target gradient coil. If they are the same, it is not necessary to reload the target gradient parameters; if they are different, it is necessary to reload the target gradient parameters.

[0059] In this embodiment, the presence or absence of different gradient coils connected before and after the magnetic resonance imaging (MRI) device is determined by checking whether the target gradient coil type is the same as the current gradient coil type corresponding to the currently applied gradient parameters. If they are different, the scanning component is started after loading the target gradient parameters; if they are the same, the scanning component is started.

[0060] In one embodiment, the method further includes: obtaining and saving the gradient parameters corresponding to the gradient coil type of each gradient coil.

[0061] In this embodiment, the gradient parameters corresponding to the gradient coil type of each gradient coil are obtained and stored in a storage device. For example, high-performance thick gradient coils and ordinary-performance thin gradient coils are both stored in the storage device. When the target gradient coil type is different from the current gradient coil type corresponding to the currently loaded gradient parameter, the corresponding target gradient parameter can be directly retrieved and loaded from the storage device, which facilitates the loading of the target gradient parameter.

[0062] In one embodiment, determining the type of the target gradient coil based on the target gradient coil connected to the magnetic resonance device includes: reading the identification information of the target gradient coil through a socket, and determining the type of the target gradient coil based on the identification information.

[0063] There is a correspondence between the identification information of the target gradient coil and the type of the target gradient coil, so the type of the target gradient coil can be determined based on the identification information.

[0064] For example, the identification information for a high-performance thick gradient coil is 1, while the identification information for a standard-performance thin gradient coil is 0. The identification information of the target gradient coil is read via a socket. If the identification information is 1, the target gradient coil type is determined to be a high-performance thick gradient coil; if the identification information is 0, the target gradient coil type is determined to be a standard-performance thin gradient coil.

[0065] In one embodiment, in order to accurately obtain the target gradient coil type, before determining the corresponding target gradient coil type based on the target gradient coil connected to the magnetic resonance device, the method further includes: determining whether the target gradient coil is connected; and if connected, obtaining the target gradient coil type.

[0066] The target gradient coil is connected to the magnetic resonance imaging (MRI) device via an interface. The connection status of the target gradient coil can be determined based on the signal from this interface, which can be the current, voltage, or resistance after connection. Understandably, when the target gradient coil is properly connected to the MRI device, the interface signal can be acquired; when the target gradient coil is not properly connected, the interface signal cannot be acquired, or the acquired interface signal is below a corresponding threshold.

[0067] In one embodiment, to ensure the normal operation of the magnetic resonance system, before determining the type of the corresponding target gradient coil based on the target gradient coil connected to the magnetic resonance device, the method further includes: determining whether the scanning components included in the magnetic resonance device are normal; and if normal, obtaining the type of the target gradient coil.

[0068] The scanning component includes a radio frequency power amplifier and a gradient power amplifier.

[0069] The scanning components may malfunction under certain circumstances, preventing the MRI system from completing the scan if it is started under such conditions. In this embodiment, before determining the type of the target gradient coil based on the target gradient coil connected to the MRI device, it is determined whether the scanning components included in the MRI device are functioning properly; if they are functioning properly, the type of the target gradient coil is obtained; thus avoiding the problem of the MRI system failing to start due to a malfunction of the scanning components.

[0070] In one embodiment, system initialization is required before the scanning component starts. Each hardware device is a component; first, all components are initialized and loaded, then the configuration and communication protocol are loaded. Next, the device component manager is initialized, and finally, the device interface processing manager is initialized.

[0071] It should be understood that although the steps in the flowchart above are shown sequentially as indicated by the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowchart above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages in other steps.
