It should be noted that the magnetic resonance apparatus relates to multiple orientations during scanning, such as a transverse position, a vector position, a crown position, a skewed vector position, a skewed crown position, a double skewed crown position, and the like, there are multiple different scanning protocols in each orientation, and some parameters in the multiple protocols need to be consistent during scanning, such as multiple contrast accelerated scanning, and at this time, if parameters in each protocol are modified separately, not only is the operation complicated, but also errors are easy to occur.
Further, if the parameter adjusting instruction adjusts not the associated parameter but the characteristic parameter in any protocol, the characteristic parameter may be added to the protocol associated display control, and it is noted that the characteristic parameter is the non-associated parameter, and the characteristic parameter is adjusted according to the parameter adjusting instruction and synchronized to the corresponding protocol.
In one embodiment, the step of creating a protocol associated display control from the associated protocol and associated parameters further comprises the steps of:
labeling the name of the associated protocol on the protocol associated display control, and writing the associated parameters into a parameter card corresponding to the protocol associated display control;
the step of adjusting the parameters of the protocol association display control according to the parameter adjustment instruction further comprises the following steps:
and adjusting the parameters in the parameter card corresponding to the protocol association display control according to the parameter adjustment instruction.
In this embodiment, in the process of creating the protocol associated display control, the name of the associated protocol may be marked on the protocol associated display control, so that when the protocol associated display control is displayed on the display device, the name of the associated protocol corresponding to the protocol associated display control may be directly displayed, which is convenient for the user to view and operate; and the associated parameters are written into the parameter cards corresponding to the protocol associated display control, and the parameter adjusting instructions can adjust the parameters in the parameter cards.
Specifically, if three associated protocols are involved when a certain azimuth is scanned by magnetic resonance, the three associated protocols are protocol a, protocol B and protocol C, each associated protocol may include the same scanning parameter and different scanning parameters, that is, protocol a, protocol B and protocol C are three different imaging sequences, and protocol a + B + C may be used as the name of the protocol associated display control, that is, the name of the associated protocol is marked on the protocol associated display control, so as to clearly display the associated protocol corresponding to the protocol associated display control.

It should be noted that the first trigger instruction and the second trigger instruction are different, the first trigger instruction is for displaying an association relationship between the protocol-associated display control and the associated protocol, and the second trigger instruction is for displaying a parameter card between the protocol-associated display control and the associated protocol.
In one embodiment, the step of obtaining the association parameter comprises the steps of:
acquiring a plurality of associated protocols, wherein each associated protocol comprises a plurality of scanning parameters; and sequentially traversing all the scanning parameters in each associated protocol, classifying the same scanning parameters in different associated protocols into associated parameters, and classifying the non-same scanning parameters in different associated protocols into characteristic parameters.
In one embodiment, the step of obtaining the association parameter comprises the steps of:
acquiring a plurality of associated protocols, wherein each associated protocol comprises a plurality of scanning parameters; and traversing all the scanning parameters in each associated protocol in sequence, and classifying the scanning parameters with linear relation in different associated protocols into associated parameters. For example, for acquisition Time (TA) in the association protocol, it is formulated as:
TA＝TR×n×NEX
wherein TA represents acquisition time; TR is the repetition time; n is the number of times TR needs to be repeated when NEX = 1; NEX is the excitation times; on the other hand, for a sequence without an echo train such as a Spin Echo (SE) sequence or a Gradient Echo (GER) sequence, n is the number of phase-encoding steps; for sequences with an echo train, such as Fast Spin Echo (FSE) or Echo Planar Imaging (EPI), n is equal to the number of phase encoding steps divided by the echo train length ETL. When the TA value in one correlation sequence is changed and the TR is kept unchanged, another correlation sequence such as FSE or EPI needs to correspondingly adjust the phase coding series or the echo chain length. In the implementation of the method, TA (timing advance), phase coding series or echo chain length of different protocols with linear relation are set as correlation parameters, so that the image effect obtained by each scanning is optimal.
In one embodiment, the step of obtaining the association parameter comprises the steps of:
the method comprises the steps of intelligently collecting scanning parameters adjusted by a doctor when the doctor manually operates protocols to be displayed for multiple times through big data, and recording the scanning parameters adjusted by the backstage when the same examinee scans by using different protocols to be displayed so as to establish a doctor operation habit database, wherein the doctor operation habit database comprises a plurality of subsets, and each subset comprises patient information and the scanning parameters adjusted by the doctor when the different protocols to be displayed are scanned. And for the object to be scanned, acquiring the information of the object to be scanned, determining a subset with the highest matching degree between the information of the object to be scanned and the patient information in the physician operation habit database, taking the scanning parameters which are contained in the subset and adjusted during scanning of different protocols to be displayed as the correlation parameters, and providing reference values for the correlation parameters based on the information in the physician operation habit database.
In one embodiment, the step of obtaining the association parameters comprises the steps of:
and receiving an input instruction, and acquiring the associated parameters according to the input instruction.
In this embodiment, a user may input an instruction into the magnetic resonance apparatus, and obtain the relevant parameters by inputting the instruction, so that a desired relevant parameter may be selected, instead of all relevant parameters, and the user may be supported to set the relevant parameters of interest, for example, in a scientific research scenario, a particular parameter may be particularly concerned, and thus, the actual operation of the magnetic resonance apparatus is adapted.
In one embodiment, the correlation parameters include the number of layers, layer thicknesses, and field angles of the magnetic resonance scan.
In this embodiment, the parameters commonly used in the magnetic resonance scanning process include the number of layers, the layer thickness, the angle of view, and the like of the magnetic resonance scanning, and the parameters generally need to be kept consistent in a plurality of scanning protocols, and especially, in the case of performing different sequence scanning in the same azimuth, the parameters are used as the associated parameters, a protocol associated display control is created, and the parameters are modified, so that the parameters in a plurality of protocols can be modified simultaneously, and the operation efficiency is improved.
Further, the relevant parameters may be adjusted according to actual needs, for example, the relevant parameters may further include a repetition Time (TR), a recovery Time (TE), a Flip Angle (FA), an average frequency (AV), an average duration (TA), and the like.
In one embodiment, the parameter adjustment method of the magnetic resonance association protocol can be applied to a scene imaged by a magnetic resonance scanning. Before scanning, for example, protocols a, B, and C are three protocols with the same orientation, the user wants parameters consistent among the three protocols, such as the number of layers, the thickness of layers, the distance between layers, FOV (field angle), TX MODE, and the like. In the conventional method, parameters such as layer thickness, layer number, FOV and the like of the protocol a are manually set, then the protocol parameters of B and C are manually set one by one, and the parameters in the layers are checked before scanning, so that the parameters are ensured to be consistent, the operation is complicated, and carelessness and omission are avoided.
Conventional protocols are generally shown by a protocol list, as shown in fig. 2, each protocol corresponds to one parameter card, and each parameter card has parameters corresponding to the protocol, as shown in fig. 3.
According to the scheme of the application, the protocol associated display control supports both associated display of related protocols and independent display, and represents the association of the protocols in brackets or other manners, as shown in fig. 4 and 5, after the protocol associated display control protocol A + B + C is clicked, not only can the relationship between the protocol A, the protocol B and the protocol C be displayed, but also the corresponding associated parameter card can be displayed, as shown in fig. 6.
The new protocol display and parameter card editing mode has the following characteristics: (1) The display of the protocol list and the protocol all in one simplifies the interface display; (2) The protocol list can visually see that the protocols are related; (3) The associated parameter card can see which parameters are associated with each other at a glance; (4) The user can directly click and add a certain parameter card in the same direction, and other contrast protocols can be edited on the basis of the click and addition, so that the workflow is simplified. The scheme of the application is particularly suitable for multi-contrast accelerated scanning, and can also give consideration to daily protocol parameter setting.
In another embodiment, it is contemplated that each individual protocol to be displayed includes multiple tabs, each tab containing multiple scan parameters. The doctor can monitor the operation of the tab for multiple times, record the frequency of the scanning parameters adjusted by the doctor during scanning each time, use the adjusted scanning parameters with the frequency exceeding the set threshold as the characteristic parameters of the protocol to be displayed, and display the characteristic parameters and the associated parameters in parallel. In this embodiment, the sequences required for the magnetic resonance scan are different, such as a Diffusion Weighted Imaging (DWI) sequence, in which the characteristic parameters include b values, average times, and the like of the diffusion weighted imaging; a fast spin echo imaging (FSE) sequence under which characteristic parameters include an Echo Train Length (ETL), and the like; an angiographic sequence under which characteristic parameters include blood vessel flow rate, etc.; navigation sequence, under which the characteristic parameters include physiological signal related parameters and the like.
