Abstract
A magnetic resonance imaging (MRI) coil device is provided. The device includes a first receiver coil portion, a second receiver coil portion, and a locking mechanism. The second receiver coil portion is configured to fit with the first receiver coil portion to provide a receiver coil assembly. The second receiver coil portion is moveable relative to the first receiver coil portion. The locking mechanism is configured to limit relative movement between the first receiver coil portion and the second receiver coil portion when the first receiver coil portion and the second receiver coil portion are fit together.
Claims20
A locking mechanism comprising:
- a locking assembly connected to a first coil structure;
- and
- an adjusting assembly connected to a second coil structure, wherein
- the locking mechanism is configured with a locking mode or an unlocking mode, and
- when the locking mechanism works in the locking mode,
- the adjusting assembly is locked by the locking assembly;
- and
- relative movement between the first coil structure and the second coil structure is limited by the locking mechanism;
- wherein the adjusting assembly includes a mounting shell fixed to the second coil structure, and an adjusting rod covered by the mounting shell, wherein
- the adjusting rod is moveable along a first direction;
- and
- before the adjusting rod reaches a first position, the adjusting rod is configured to move along with the mounting shell along the first direction.
A method comprising
- causing an adjusting assembly to move toward a locking assembly along a first direction before an adjusting rod reaches a first position, wherein the adjusting assembly is fixed to a second coil structure and the locking assembly is fixed to a first coil structure;
- after the adjusting rod passes the first position along the first direction, rotating a knob of the adjusting assembly to drive the adjusting rod further to move toward the locking assembly;
- and
- locking the adjusting assembly by the locking assembly.
