Fixation mechanism and a MRI system

A fixation mechanism for fixing a flex coil unit of a MRI system onto a patient comprising:

• an elongated slot extending from a longitudinal surface formed at least partially by a housing of the MRI system, an axis of the elongated slot extending at an oblique angle relative to the longitudinal surface;
• an oblique-shaped clip comprising a first portion and a second portion forming the oblique angle therebetween, the first portion being configured to be connected with a strap, the second portion being configured to be slidingly received when the strap is not under tension in the slot with the first portion extending along and overlaying the longitudinal surface to a first side of the slot, the oblique-shaped clip further including a projection extending along and overlaying the longitudinal surface on a second side of the slot across the slot from the first side of the slot, the oblique-shaped clip being configured to pivot about the projection as the projection engages the longitudinal surface causing the second portion to abut and frictionally engage against a side wall of the elongated slot with sufficient frictional engagement with the side wall to forestall removal of the second portion from the elongated slot when the strap is under tension.

A fixation mechanism for fixing a coil unit of an MRI system to a patient, the MRI housing including a supporting portion laterally projecting from a longitudinal side of a main body of the housing along a longitudinal direction, the fixing mechanism comprising:

• an elongated body fixed removably onto the supporting portion so that an elongated slot is defined between the main body of the housing and the elongated body, the elongated slot extending at an oblique angle to a longitudinal plane defined by the elongated body and the supporting portion;
• an oblique-shaped clip in a first portion and a second portion extending at an oblique angle to each other, the second portion being configured to be slidingly received in the slot, the first portion being configured to overlay the elongated body when the second portion is received in the slot, the oblique-shaped clip further including a projection configured to overlay the main body of the housing when the second portion is received in the slot such that a force transverse to the longitudinal plane on the first portion causes the clip to pivot such that the projection is pressed against the main body and the second portion frictionally engages a side of the slot defined by the elongated body.
