Example two
Fig. 4 is a flowchart of a magnetic resonance scanning method according to a second embodiment of the present invention, and the technical solution of this embodiment is further elaboration on the basis of the foregoing embodiment. Optionally, the performing a magnetic resonance scanning operation on the tested object based on each radio frequency unit set includes: displaying each radio frequency unit set on an interactive interface, and determining at least one target radio frequency unit set selected by a user based on the interactive interface; and performing magnetic resonance scanning operation on the tested object based on each target radio frequency unit set.
The specific implementation steps of the embodiment include:

And S230, displaying each radio frequency unit set on the interactive interface, and determining at least one target radio frequency unit set selected by a user based on the interactive interface.
The radio frequency unit set is exemplarily displayed on the interactive interface in a key manner, and specifically, the user can select the target radio frequency unit set based on the key corresponding to the radio frequency unit set.
In one embodiment, optionally, the interactive interface further includes a coil following option, and accordingly, determining at least one target radio frequency unit set selected by the user based on the interactive interface includes: and acquiring the selection state of the coil following options on the interactive interface, and determining at least one target radio frequency unit set according to the selection state.
Wherein, illustratively, the coil following option is displayed on the interactive interface in the form of a selection box, which when selected, indicates that the selection status of the coil following option is selected. When the selection box is not selected, the selection state indicating the coil following option is not selected.
In one embodiment, optionally, determining at least one target set of radio units according to the selection status includes: if the selection state is selected, when at least two coil sockets inserted into the coil plugs are changed but the placement state is unchanged, the current target radio frequency unit set is the same as the previous target radio frequency unit set; if the selected state is unselected, when at least two coil sockets of the inserted coil plug are changed but the placement state is unchanged, the current target radio frequency unit set is an empty set.
In this example, it is assumed that the socket area a includes a coil socket 1, a coil socket 2, a coil socket 3, and a coil socket 4, and the coil socket into which the coil plug is inserted is changed from the coil socket 1 and the coil socket 2 to the coil socket 3 and the coil socket 4, and since the coil socket 1 and the coil socket 2, and the coil socket 3 and the coil socket 4 belong to the socket area a, the placement state is laterally set although at least two coil sockets into which the coil plug is inserted are changed. If the selection state of the coil following option is selected, the current target radio frequency unit set for executing the magnetic resonance scanning operation on the tested object is the same as the previous target radio frequency unit set. If the selection state of the coil following option is unselected, the current target radio frequency unit set for executing the magnetic resonance scanning operation on the tested object is irrelevant to the previous target radio frequency unit set, and the current target radio frequency unit set is an empty set, so that the current target radio frequency unit set selected by the user based on the interactive interface needs to be acquired again.
In one embodiment, optionally, the interactive interface further comprises at least one of a display frame of the coil jack, a display frame of the treatment couch, and a body coil icon. Fig. 5A is a schematic diagram of an interactive interface corresponding to a lateral positioning according to a second embodiment of the present invention, and fig. 5A takes the number of coil sockets as 8 as an example. The center position in fig. 5A indicates a treatment couch, 8 boxes on the treatment couch indicate coil sockets, the "VTC" on the treatment couch indicates a body coil, and 4 rectangular display boxes on the left and right sides of the treatment couch correspond to the coil sockets on the treatment couch, respectively, and the type of magnetic resonance coil and the socket information are displayed in the display boxes, by way of example. As shown in fig. 5A, "Body Array Coil-24 (W)" in the display frame corresponding to the Coil socket into which the Coil plug is inserted indicates that the width of the Body Array Coil is 24, that is, the Body Array Coil contains 24 radio frequency units. "(1/2)" and "(2/2)" indicate coil plug numbers/coil plug total numbers. "Follow Coils" in fig. 5A represents a coil following option.
As shown in fig. 5A, the body coil divides the coil sockets on the treatment couch into 2 socket areas, the 4 coil sockets in the upper area in fig. 5A belong to the same socket area, and the 4 coil sockets in the lower area in fig. 5A belong to another socket area. As shown in fig. 5A, 2 coil sockets with smaller gray values on the treatment table represent coil sockets into which coil plugs are inserted, and 6 coil sockets with larger gray values represent coil sockets into which coil plugs are not inserted. The coil sockets inserted with the coil plugs belong to the same socket area, and the current arrangement state of the magnetic resonance coil is represented as transverse arrangement. Wherein BAW1, BAW2, BAW3 and BAW4 represent 4 radio frequency unit sets obtained by grouping row vectors in the laterally-positioned radio frequency unit matrix.
Fig. 5B is a schematic diagram of an interactive interface corresponding to vertical positioning according to a second embodiment of the present invention, as shown in fig. 5B, coil sockets of 2 plugs inserted into coils with smaller gray values on a treatment table do not belong to the same socket area, which indicates that the current placement state of a magnetic resonance coil is vertical positioning. Wherein, BAL1, BAL2, BAL3, BAL4, BAL5 and BAL6 represent 6 radio frequency unit sets obtained by grouping row vectors in a vertically-positioned radio frequency unit matrix.
S240, performing magnetic resonance scanning operation on the tested object based on the target radio frequency unit set.
In the magnetic resonance scanning process, because the types of the magnetic resonance coils are various, and the number of the radio frequency units contained in different magnetic resonance coils is different, if only the radio frequency unit set obtained by grouping is displayed to a user, the user also needs to analyze and judge whether the current radio frequency unit set obtained by grouping is the radio frequency unit set required by the magnetic resonance scanning. According to the technical scheme, the problem that the grouping mode of the radio frequency unit set is ambiguous is solved by designing the interactive interface for the radio frequency unit set, so that a user can clearly check the placement state of the magnetic resonance coil and the grouping result of the radio frequency unit through the interactive interface. Furthermore, the technical scheme also sets a coil following option on the interactive interface, thereby further simplifying the operation steps in the magnetic resonance scanning process and improving the magnetic resonance scanning efficiency.
