Description

Technical Field

[0001] The present application relates to the field of magnetic resonance imaging technology, and in particular to a method, device, system and computer equipment for determining a magnetic resonance protocol. Background Art

[0002] In current medical imaging systems, such as magnetic resonance tomography (MRI), computed tomography (CT), or ultrasound systems, the MRI protocol used to perform an examination is manually configured on each device. MRI protocols are typically configured on the device prior to the imaging examination. MRI protocols contain scanning parameters that the operator can select based on the patient's specific examination requirements. As more and more MRI protocols are created and stored for easy access, selecting the most appropriate MRI protocol from the large number of stored protocols becomes increasingly laborious for the user.

[0003] Conventional technologies also employ the use of protocol manager search functions to select MRI protocols. Currently, most protocol manager search functions filter based on protocol names. This requires the operator to be familiar with protocol naming conventions. Furthermore, the search criteria are relatively simple, making it difficult to select the appropriate protocol at once. Multiple protocols must be manually opened to filter the desired protocol. Summary of the Invention

[0007] If not, matching the at least two first protocol conditions with at least one preset protocol to determine a corresponding target protocol;

[0008] If so, the first protocol condition and the second protocol condition are matched with at least one preset protocol to determine a corresponding target protocol, wherein the second protocol condition is obtained by resetting at least one of the conflicting first protocol conditions.

[0009] In one embodiment, determining whether there is a condition conflict between the at least two first protocol conditions based on the set at least two first protocol conditions includes:

[0010] Determining whether the at least two first protocol conditions satisfy a preset condition conflict rule;

[0012] In one embodiment, matching the at least two first protocol conditions with at least one preset protocol to determine the corresponding target protocol includes:

[0013] If there is a preset protocol that matches the at least two first protocol conditions, determining the preset protocol as the target protocol;

[0014] If there is no preset protocol matching the at least two first protocol conditions, at least one matching degree between the at least two first protocol conditions and the at least one preset protocol is obtained, and a target protocol is determined based on the at least one matching degree.

[0016] determining whether a highest matching degree among at least two matching degrees is greater than a set threshold;

[0017] If yes, the preset protocol corresponding to the highest matching degree is determined as the target protocol; if not, the matching degree is re-obtained based on the first protocol condition after the parameter modification, and the preset protocol corresponding to the highest matching degree is determined as the target protocol.

[0018] In one embodiment, before re-obtaining the matching degree based on the first protocol condition after parameter modification, the method further includes:

[0019] Determining whether the highest matching degree among the reacquired matching degrees after modifying the parameters corresponding to the first protocol condition is greater than a set threshold;

[0020] If so, modify the parameters in the corresponding first protocol condition; if not, reset the first protocol condition or use the preset protocol corresponding to the highest matching degree as the target protocol.

[0021] In one embodiment, the method further comprises:

[0022] Based on the priorities corresponding to the at least two first protocol conditions, at least one matching degree between the at least two first protocol conditions and the at least one preset protocol is obtained.

[0023] In one embodiment, the method further comprises:

[0024] Determining whether parameters in the target protocol satisfy a dependency relationship;

[0025] If not, the corresponding parameters in the target protocol are modified.

[0026] In a second aspect, an embodiment of the present invention provides a device for determining a magnetic resonance protocol, the device comprising:

[0027] A first determining module is configured to determine, based on the at least two first protocol conditions that are set, whether there is a condition conflict between the at least two first protocol conditions;

[0028] The second determination module is configured to, if not, match the at least two first protocol conditions with at least one preset protocol to determine a corresponding target protocol; and if so, match the first protocol condition and the second protocol condition with at least one preset protocol to determine a corresponding target protocol, wherein the second protocol condition is obtained by resetting at least one of the conflicting first protocol conditions.

[0029] In a third aspect, an embodiment of the present invention provides a magnetic resonance system, comprising a scanning device for performing multi-circle scanning to obtain scanned data, and a device for determining the magnetic resonance protocol as described in the second aspect, connected to the scanning device.

This technical solution takes into account the conditional conflict between the set first protocol conditions and automatically obtains the target protocol, avoiding the situation where the magnetic resonance system cannot scan normally due to the conditional conflict when performing a scan based on the target protocol, thereby improving the accuracy and efficiency of the target protocol determination.

In some embodiments, the scanning device 110 can be a magnetic resonance imaging (MRI), a computed tomography (CT), a positron emission computed tomography (PET), etc. In some embodiments, the scanning device 110 can also be a combination of the above-mentioned devices, such as a PET-CT scanner, a PET-MRI scanner, etc. The scanning device 110 can generate scanned data corresponding to the object after scanning. Furthermore, the scanning device 110 can send the acquired scanned data to the processing device 120, the storage device 140, or the display device 150 via the network 130.

[0052] Figure 2 This is a flow chart of determining a magnetic resonance protocol provided by an embodiment of the present invention. In some embodiments, the process can be implemented by a magnetic resonance protocol determination device. In one embodiment, Figure 2 As shown, a method for determining a magnetic resonance protocol is proposed, comprising the following steps:

[0053] S201: Based on at least two set first protocol conditions, determine whether there is a condition conflict between the at least two first protocol conditions.

[0054] The first protocol conditions are stored in the database of the storage device 140. The operator can set the first protocol conditions according to the scanning requirements, such as name, body part, fat suppression, channel compression, etc. The user can further add conditions by selecting parameters on each parameter card.

[0055] It is understood that conflicting MRI protocols may cause the MRI system to malfunction. Therefore, in step S201, a determination is made as to whether there is a conflict between the first protocol conditions. For example, a conflicting condition may occur where one first protocol condition specifies acceleration for parallel acquisition, while another first protocol condition specifies acceleration for compressed sensing. Another example is where one first protocol condition lacks inversion recovery, while another first protocol condition specifies inversion time.

[0056] S202: If not, match the at least two first protocol conditions with at least one preset protocol to determine a corresponding target protocol; if so, match the first protocol condition and the second protocol condition with at least one preset protocol to determine a corresponding target protocol.

[0057] The second protocol condition is obtained by resetting at least one of the first protocol conditions that have a conflicting condition.

[0058] In the event of a conflict between first protocol conditions, one or two of the conflicting first protocol conditions are reset to obtain a second protocol condition until there is no conflict. For example, the second protocol condition is set to replace one of the conflicting first protocol conditions.

[0059] The preset protocols are stored in a database on storage device 140, and a matching method is used to determine the target protocol. When a preset protocol exists, at least two first protocol conditions are simultaneously matched against the preset protocol to determine whether the preset protocol is the target protocol. When at least two preset protocols exist, at least two first protocol conditions are simultaneously matched against each preset protocol to determine the target protocol among the at least two preset protocols. For example, if a preset protocol matches all first protocol conditions, the preset protocol is determined to be the target protocol.

[0060] The target protocol can be understood as one or more protocols recommended by the processing device 120 based on the above method. The final protocol used by the magnetic resonance system needs to be confirmed by the user. For example, when there are multiple target protocols, the user selects one of them as the final protocol.

[0061] In the above steps S201-S202, based on the at least two set first protocol conditions, it is determined whether there is a conditional conflict between the at least two first protocol conditions; if not, the at least two first protocol conditions are matched with at least one preset protocol to determine the corresponding target protocol; if so, the first protocol condition and the second protocol condition are matched with at least one preset protocol to determine the corresponding target protocol, wherein the second protocol condition is obtained by resetting at least one of the first protocol conditions that has a conditional conflict. This technical solution takes into account the conditional conflict between the set first protocol conditions and automatically obtains the target protocol, thereby avoiding the situation where the magnetic resonance system cannot perform normal scanning due to conditional conflicts when performing scanning based on the target protocol, thereby improving the accuracy and efficiency of determining the target protocol.

[0062] In one embodiment, if Figure 3 As shown, the determining whether there is a condition conflict between the at least two first protocol conditions based on the set at least two first protocol conditions includes the following steps:

[0063] S301: Determine whether the at least two first protocol conditions satisfy a preset condition conflict rule;

[0064] S302: If yes, determine that there is a condition conflict between the corresponding first protocol conditions; if no, determine that there is no condition conflict between the at least two first protocol conditions.

[0065] The condition conflict rules may be manually set and stored in the database of the storage device 140 .

[0066] Condition conflict rules include but are not limited to parallel condition conflicts, such as the condition conflict between parallel acquisition and compressed sensing; constraints between conditions, such as the condition conflict between no inversion recovery and setting inversion time.

[0067] If there is a conflicting condition, the operator is prompted with the first protocol condition with the conflicting condition, and is instructed to reset one or both of the conflicting conditions.

[0068] In one embodiment, if Figure 4 As shown, matching the at least two first protocol conditions with at least one preset protocol to determine the corresponding target protocol includes the following steps:

[0069] S401: If there is a preset protocol that matches the at least two first protocol conditions, determine the preset protocol as the target protocol;

[0070] S402: If there is no preset protocol matching the at least two first protocol conditions, obtaining at least one matching degree between the at least two first protocol conditions and the at least one preset protocol, and determining a target protocol based on the at least one matching degree.

[0071] In this embodiment, considering that there is no preset protocol that matches all the first protocol conditions, the matching degree with each preset protocol is obtained, and the target protocol is determined based on the matching degree. A matching degree of 100% indicates that all the first protocol conditions meet the preset protocol.

[0072] In some embodiments, if there are multiple preset protocols that match the at least two first protocol conditions, the multiple matching preset protocols may be displayed, and a final protocol may be determined through user selection.

[0073] In some embodiments, the matching degree may be determined based on the number of matching items of the first protocol condition, or the matching degree may be determined by setting a weight for each first protocol condition.

[0074] In some embodiments, if there is a matching degree, it is determined whether the matching degree is greater than a set threshold. If so, the preset protocol is used as the target protocol.

[0075] The set threshold can be set manually by the user. Only when there is no preset protocol matching the at least two first protocol conditions, the target protocol is determined by judging whether the matching degree is greater than the set threshold.

[0076] In some embodiments, if there are at least two matching degrees, the obtained matching degrees are sorted from high to low, and the preset protocol with the highest matching degree is selected as the target protocol.

[0077] If there are at least two preset protocols with the highest matching degree, the final protocol can be determined by user selection.

[0078] It should be noted that the above method is also used for the second agreement condition reset by the first agreement condition, so it will not be described in detail.

[0079] In one embodiment, if Figure 5 As shown, there are at least two preset protocols and at least two matching degrees, and determining the target protocol based on the at least one matching degree includes the following steps:

[0080] S501: Determine whether the highest matching degree among at least two matching degrees is greater than a set threshold;

[0081] S502: If yes, determine the preset protocol corresponding to the highest matching degree as the target protocol; if not, re-acquire the matching degree based on the first protocol condition after parameter modification, and determine the preset protocol corresponding to the highest matching degree as the target protocol.

[0082] If there are at least two preset protocols with the highest matching degree, the final protocol can be determined by user selection.

[0083] In this embodiment, considering that there is no preset protocol that matches all the first protocol conditions and the highest matching degree is less than a set threshold (for example, 90%), if the preset protocol corresponding to the highest matching degree is still selected as the target protocol, it may be quite different from the target protocol actually required. Therefore, the operator is prompted to modify the parameters in the corresponding first protocol condition to improve the matching degree, and re-obtain the matching degree based on the first protocol condition after the parameter modification, and then determine the preset protocol corresponding to the highest matching degree as the target protocol.

[0084] In one embodiment, if Figure 6 As shown, before re-acquiring the matching degree based on the first protocol condition after parameter modification, the method further includes the following steps:

[0085] S601: Determine whether the highest matching degree among the re-obtained matching degrees after modifying the parameters corresponding to the first protocol condition is greater than a set threshold;

[0086] S602: If yes, modify the parameters in the corresponding first protocol condition; if no, reset the first protocol condition or use the preset protocol corresponding to the highest matching degree as the target protocol.

[0087] Considering the situation where the highest degree of match is still less than the set threshold even after modifying the parameters corresponding to the first protocol condition, a determination is required before modifying the parameters. If the highest degree of match among the newly obtained degrees of match is greater than the set threshold, the parameters are modified. If the highest degree of match among the newly obtained degrees of match is less than or equal to the set threshold, the first protocol condition is reset according to the operator's needs, or the preset protocol corresponding to the highest degree of match is used as the target protocol.

[0088] If there are at least two preset protocols with the highest matching degree, the final protocol can be determined by user selection.

[0089] It should be noted that the above method is also used for the second agreement condition reset by the first agreement condition, so it will not be described in detail.

[0090] In one embodiment, the method further comprises the following steps:

[0091] Based on the priorities corresponding to the at least two first protocol conditions, at least one matching degree between the at least two first protocol conditions and the at least one preset protocol is obtained.

[0092] In this embodiment, after setting the first protocol condition, the priority corresponding to the first protocol condition is set, and then the matching degree corresponding to each preset protocol is obtained based on the priority. Since the priority of each first protocol condition is taken into account, the target protocol finally obtained better meets the operator's needs.

[0093] In some example embodiments, after matching with each preset protocol, they are sorted from high to low according to priority, and the first protocol condition with the highest priority corresponds to the highest weight. The weight of each preset protocol is then calculated based on each weight, and the weight is then converted into a matching degree.

[0094] It should be noted that the above method is also used for the second agreement condition reset by the first agreement condition, so it will not be described in detail.

[0095] In one embodiment, if Figure 7 As shown, the method further includes the following steps:

[0096] S701: Determine whether the parameters in the target protocol satisfy the dependency relationship;

[0097] S702: If not, modify the corresponding parameters in the target protocol.

[0098] Specifically, a copy protocol is created for the target protocol, parameters are extracted according to the copy protocol, and it is determined whether the parameters in the target protocol meet the dependency relationship. If not, the corresponding parameters in the target protocol are modified to generate a new target protocol.

[0099] The dependency relationship may be manually set and stored in the database of the storage device 140 .

[0100] In an example embodiment, a first protocol condition is that the value of parameter a is b. The parameter dependencies for parameter a being b are: the value of parameter c is d and the value of parameter a is b. If the value of parameter c in the target protocol-related condition is e or the value of parameter a is f, then the corresponding parameters are determined to not satisfy the dependency.

[0101] In this embodiment, the dependency relationship of the parameters in the target protocol is detected and modified to further improve the accuracy of the target protocol.

[0102] In one embodiment, the overall process of the method for determining the magnetic resonance protocol is as follows: Figure 8 As shown, first set the first protocol conditions, there are at least two first protocol conditions, and then set the corresponding priorities. Determine whether there is a condition conflict between the first protocol conditions. If so, reset the corresponding first protocol conditions. If not, match the first protocol conditions with the preset protocol. Determine whether there is a preset protocol that matches the first protocol condition. If so, determine the preset protocol as the target protocol. If the parameters in the target protocol meet the dependency relationship, do not modify the parameters. If not, modify the corresponding parameters. If there is no matching preset protocol, obtain the matching degree. If the highest matching degree is greater than the set threshold, determine the preset protocol corresponding to the highest matching degree as the target protocol. If the highest matching degree is less than or equal to the set threshold, determine whether the highest matching degree in the re-acquired matching degrees is greater than the set threshold. If so, modify the parameters in the corresponding first protocol condition and re-acquire the matching degree. Otherwise, reset the first protocol condition or set the preset protocol corresponding to the highest matching degree as the target protocol.

[0103] It should be understood that, although the various steps in the above flow chart are shown in sequence as indicated by the arrows, these steps are not necessarily performed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the above flow chart may include multiple steps or multiple stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily to be performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of steps or stages in other steps.

[0104] In some embodiments, as Figure 9 As shown, the present invention provides a device for determining a magnetic resonance protocol, the device comprising:

[0107] In the above embodiment, based on the at least two set first protocol conditions, it is determined whether there is a conditional conflict between the at least two first protocol conditions; if not, the at least two first protocol conditions are matched with at least one preset protocol to determine the corresponding target protocol; if so, the first protocol condition and the second protocol condition are matched with at least one preset protocol to determine the corresponding target protocol, wherein the second protocol condition is obtained by resetting at least one of the first protocol conditions that has a conditional conflict.
