RF COIL ASSEMBLY AND MRI APPARATUS
20220221538 · 2022-07-14 ·

The present invention provides a RF coil assembly comprising a first rigid frame and a flexible coil in a naturally planar shape having a first end, a second end opposite the first end and a longitudinal axis extending from the first end to the second end. The first end of the flexible coil is attached to the first rigid frame and the second end of the flexible coil is away from the first rigid frame. The first rigid frame is shaped to bend the flexible coil, upon attaching the first end of the flexible coil to the first rigid frame, to form a shape of the RF coil assembly which conforms to a shape of a region of a subject with multiple contours. According to the present invention, the RF coil assembly is lighter and better matches the regions of different subjects to be imaged. The contoured shape of the RF coil assembly can be maintained for immediate use instead of having to achieve the shape by an operator attaching the flexible coil to body regions. Therefore, the positioning and fastening of the RF coil assembly is much easier and faster as compared to the conventional flexible coil, and the workflow of MR scanning is enhanced.
