    摘要: There is provided an RF (radio frequency) coil assembly of a magnetic resonance imaging (MRI) system, which comprises a birdcage transmit-only coil using inhomogeneous modes. Further, a multi-channel receive-only phased array coil is provided. In one embodiment, the multi-channel receive-only phased array coil may include a plurality of ring-shaped receive-only coils, wherein the receive-only coils are connected to each other in a pseudo-chain-link configuration to form a ring shape. The multi-channel receive-only phased array coil may be located inside said transmit-only coil and spaced a predetermined distance apart therefrom. In accordance with the embodiments, emphasis images of the peripheral part of a human brain with high resolution and high signal to noise ratio may be obtained.

    摘要: An RF (radio frequency) coil assembly of a magnetic resonance imaging (MRI) system, which has a spiral-shaped coil and a plurality of sections. In one embodiment, an RF coil of a magnetic resonance imaging (MRI) system has a plurality of ring-shaped end-rings arranged vertically and a plurality of rods. Each of the rods are connected to the plurality of end-rings. Adjacent end-rings of the plurality of end-rings forms respective coil sections and each of the coil sections has switching blocks located between adjacent rods of the plurality of rods. The switching blocks are operable to control the continuity status of the plurality of rods in the respective coil section.
