Illustratively, the coil following option is displayed on the interactive interface in the form of a selection box, and when the selection box is selected, the selection state of the coil following option is selected. When the selection box is not selected, the selection state of the coil following option is indicated as unselected.
In an embodiment, optionally, determining at least one target radio frequency unit set 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; and if the selection state is unselected, when at least two coil sockets inserted into the coil plugs are changed but the placement state is not changed, the current target radio frequency unit set is an empty set.
Wherein, exemplarily, assuming that the socket area a includes the coil socket 1, the coil socket 2, the coil socket 3 and the coil socket 4, the coil socket inserted into the coil plug is changed from the coil socket 1 and the coil socket 2 to the coil socket 3 and the coil socket 4, since the coil socket 1 and the coil socket 2, and the coil socket 3 and the coil socket 4 both belong to the socket area a, although at least two coil sockets inserted into the coil plug are changed, the placement state is still a horizontal placement. And 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 last target radio frequency unit set. If the selection state of the coil following option is not selected, the current target radio frequency unit set for executing the magnetic resonance scanning operation on the measured object is irrelevant to the previous target radio frequency unit set, and the current target radio frequency unit set is an empty set, and the current target radio frequency unit set selected by the user based on the interactive interface needs to be obtained again.
In one embodiment, optionally, the interactive interface further comprises at least one of a display frame of the coil socket, a display frame of the treatment couch, and a body coil icon. Fig. 5A is a schematic view of an interaction interface corresponding to lateral positioning according to a second embodiment of the present invention, and fig. 5A illustrates that the number of coil sockets is 8. The center position in fig. 5A represents the treatment couch, 8 boxes on the treatment couch represent the coil sockets, the "VTC" on the treatment couch represents the body coil, and the 4 rectangular display frames on the left and right sides of the treatment couch correspond to the coil sockets on the treatment couch, respectively, and exemplarily, the type of the magnetic resonance coil and the socket information are displayed in the display frames. As shown in fig. 5A, "Body Array Coil-24 (W)" in the display frame corresponding to the Coil socket of the inserted Coil plug 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 a coil plug number/total number of coil plugs. "Follow Coils" in FIG. 5A represents the coil following option.
As shown in fig. 5A, the body coil divides the coil sockets on the treatment couch into 2 socket regions, 4 coil sockets in the upper region in fig. 5A belong to the same socket region, and 4 coil sockets in the lower region in fig. 5A belong to another socket region. As shown in fig. 5A, 2 coil sockets having a smaller gray value on the treatment couch represent coil sockets into which coil plugs are inserted, and 6 coil sockets having a larger gray value represent coil sockets into which coil plugs are not inserted. And the coil sockets inserted into the coil plugs belong to the same socket area, and the current arrangement state of the magnetic resonance coil is the transverse arrangement state. Wherein, BAW1, BAW2, BAW3 and BAW4 represent 4 radio cell sets obtained by grouping row vectors in the transversely arranged radio cell matrix.
Fig. 5B is a schematic diagram of an interaction interface corresponding to vertical positioning according to a second embodiment of the present invention, and as shown in fig. 5B, the coil sockets of 2 inserted coil plugs with smaller gray values on the treatment couch do not belong to the same socket area, which indicates that the current placement state of the 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 the vertically arranged radio frequency unit matrix.
And S240, performing magnetic resonance scanning operation on the measured 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 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 not clear is solved by designing the interactive interface for the radio frequency unit set, so that a user can clearly check the arrangement state of the magnetic resonance coils and the grouping result of the radio frequency units 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 efficiency of the magnetic resonance scanning.
