Abstract

The invention relates to a radio frequency coil device for magnetic resonance mammary gland imaging. The radio frequency coil device comprises a coil supporting shell, a breast containing cavity formed by the coil supporting shell, two breast placing holes communicated with the breast containing cavity and a plurality of radio frequency coils located on the outer side of the breast containing cavity. The plurality of radio frequency coils comprise two first annular coils which are respectively arranged around the peripheries of the two breast placing holes; the plurality of radio frequency coils further comprise two second annular coils which are respectively arranged at the front sides of the two first annular coils, and two saddle-shaped coils which are respectively arranged at the front sides of the two first annular coils; each first annular coil and one saddle-shaped coil on the front side of the first annular coil form a first orthogonal coil pair, and the second annular coil and the saddle-shaped coil on the front side of the same first annular coil form a second orthogonal coil pair. A radio frequency coil array has a more reasonable structure, so that clearer magnetic resonance images can be obtained.

Description

technical field [0001] The present application relates to the field of magnetic resonance imaging, in particular to a radio frequency coil device for magnetic resonance breast imaging. Background technique [0002] A magnetic resonance system is a medical imaging device, wherein a radio frequency (RF, Radio Frequency) receiving coil is a very important component of the magnetic resonance system. The role of the RF receiving coil in it can be compared to the eyes of an adult, and the final clarity of the image is directly proportional to its signal-to-noise ratio (sensitivity). In order to improve the clarity of the image (or signal-to-noise ratio, or sensitivity), the primary starting point for general coil design is to determine the shape of the coil and the size of the inner cavity, and the size can neither be too large nor too small. Because if the size of the coil is too large, the clarity of the magnetic resonance image will be reduced; if it is too small, a considerab...
