no. 2 Embodiment

[0044] The shoulder coil according to the second specific embodiment of the present invention includes a base plate for fixing the shoulder coil on a hospital bed; a main body; elastic wings; connecting wires and interfaces. Wherein, the main body 301 is located between the substrate and the elastic wing, that is, one side (lower side) of the main body is connected to the substrate and the other side (upper side) is connected to the elastic wing; the connecting wire is electrically connected between the main body and the interface. The connection between the two, so as to conduct the signal between the two; the interface and the connection line are used to send the signal to the magnetic resonance system.

[0045] The shell of the main body is made of hard plastic, which is manufactured by molding processes such as mold injection molding, blister molding or resin casting. The main body has a semi-spherical curved surface, thereby forming a space for accommodating the shoulder ...

Abstract

The invention provides a local coil which comprises a body part. The body part comprises an inner conductor layer. A shoulder coil further comprises at least one elastic wing, wherein an accommodating space used for accommodating a detected part is formed by the body part and the at least one elastic wing. According to the local coil used for a magnetic resonance imaging system, one shoulder coil can be applied to different shoulder forms of different detected objects, and complicated work procedures caused by trial of different shoulder coils are avoided; meanwhile, the comfort level of the detected objects is increased, durability of the coil is improved, and positioning and removing can be achieved simply and flexibly; furthermore, due to the arrangement of the rigid body part, the shape of the inner conductor layer is accurate and reliable in use, and the influence of shoulder movement is reduced.

Description

technical field [0001] The present invention relates to magnetic resonance imaging systems, in particular to local coils for magnetic resonance imaging systems. Background technique [0002] Magnetic resonance imaging systems typically operate with a number of various radio frequency (RF) antennas (hereinafter referred to as coils) used to transmit and receive radio frequency pulses to excite nuclei to emit magnetic resonance signals and / or to acquire evoked magnetic resonance signals. Magnetic resonance systems typically have large whole-body coils (body coils) that are permanently installed in the magnetic resonance scanner. The whole-body coil is typically arranged in a cylindrical fashion (for example, using a structure known as a birdcage) around the patient acquisition chamber where the patient is supported on a bed (also commonly referred to as a bed) during measurements. on the patient positioning table). [0003] To improve the signal-to-noise ratio (SNR) in magn...
