AI Technical Summary
Existing ankle coils are heavy, inconvenient to operate, and prone to plug damage, affecting user experience and image quality.
Design an ankle coil including a support shell and a cover plate. The support shell consists of first and second support parts, and the cover plate is rotatably connected. The coil units are distributed on each support part and the cover plate. The opening and closing are achieved by rotating the cover plate, avoiding plug connection and enhancing portability and stability.
It improves the portability and imaging quality of the ankle coil, reduces the risk of plug damage, and enhances the stability and comfort of use.

Abstract
Claims
1. Ankle coil, characterized in that include: A support housing (100) comprising: A first support portion (110) extends along a first direction (X) and is used to support the ball of the foot. A second support portion (120) is connected to the first support portion (110). The second support portion (120) extends along a second direction (Y) perpendicular to the first direction (X) and is used to support the heel and lower leg. An opening (121) for the foot to enter and exit is formed on the second support portion (120). A cover plate (130) rotatably connected to the first support (110) with its axis of rotation parallel to a third direction (Z), the third direction (Z) being perpendicular to the first direction (X) and the second direction (Y), the cover plate (130) being rotatable to open or close the opening (121); and Several coil units (200) are respectively disposed in the first support (110), the second support (120) and the cover plate (130), such that when the cover plate (130) closes the opening (121), each coil unit (200) overlaps with at least one of the remaining coil units (200).
2. The ankle bracelet of claim 1, wherein, The first support portion (110) has a first overlapping portion (112) near the opening (121), and a portion of the coil unit (200) on the first support portion (110) is located in the first overlapping portion (112). The second support portion (120) has two second overlapping portions (122) on both sides of the opening (121) along the third direction (Z), and a portion of the coil unit (200) on the second support portion (120) is located in the second overlapping portion (122). When the cover plate (130) closes the opening (121), the coil unit (200) on the cover plate (130) overlaps with the coil unit (200) in the first overlapping portion (112) and the second overlapping portion (122), respectively.
3. The ankle bracelet of claim 2, wherein, The outer surface of the first support portion (110) is recessed inward at the first overlapping portion (112), and the outer surface of the second support portion (120) is recessed inward at the second overlapping portion (122). When the cover plate (130) closes the opening (121), the cover plate (130) can be embedded in the first support portion (110) and the second support portion (120).
4. The ankle coil of claim 1, wherein, A connector (113) is provided on the first support part (110), which is located on the outside of the first support part (110) corresponding to the foot. The connector (113) is connected to several of the coil units (200).
5. The ankle coil of claim 4, wherein, The coil unit (200) on the cover plate (130) is connected to the connector (113) via a wire.
6. The ankle coil of claim 1, wherein, The ankle coil also includes an airbag (300) disposed inside the first support (110) at a position corresponding to the instep. The airbag (300) can be inflated and deflated to fix or release the foot portion inside the first support (110).
7. The ankle coil of claim 1, wherein, The second support (120) is provided with an inner liner (123), and the inner liner (123) has a recess formed thereon for supporting the rear of the heel and the rear of the distal end of the lower leg.
8. The ankle coil as described in claim 1, characterized in that, The ankle coil also includes a stand (400) that can be placed on the bed surface and support the support housing (100) such that the first direction (X) is perpendicular to the bed surface.
9. The ankle coil of claim 1, wherein, The cover plate (130) is hinged to the first support (110) via a hinge shaft (140).
10. A magnetic resonance imaging system, characterized by The ankle coil includes any one of claims 1 to 9.
