Problems solved by technology

However, with the increase of the coil unit, the diameter of the cable connected to it also increases; and the connection part between the cable and the local coil is mostly a fixed structure, and the outlet method is greatly restricted, which is not conducive to the user's use.

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Such as Figure 1-5 As shown, the preferred embodiment of the present invention is a radio frequency coil assembly 100 for magnetic resonance imaging including a radio frequency coil 10 and a cable connector 20 . This embodiment is a head RF coil assembly, but the technical solution in the present invention can also be applied to limb joint RF coil assemblies, abdominal RF coil assemblies, and other RF coil assemblies or local coil assemblies that can be used for magnetic resonance imaging.

[0028] The radio frequency coil 10 includes a housing, and several coil units supported (fixed) by the housing. The housing is made of non-magnetic material, which may be insulating material or other materials. For ease of use, the housing is designed as an upper housing (upper half) 101 and a lower housing (lower half), the lower housing includes a lower ...

Abstract

Provided herein is a radio frequency (RF) coil assembly. The RF coil assembly includes one or more coil elements arranged on a shell, a cable connector electrically connected to the coil elements, the cable connector including a number of inner wires enclosed with an outer insulative jacket, and the cable having a first end connect to a connector and a second end rotatably connected with the shell, and the inner wires exposed outwardly of the outer insulative jacket of the second end of the cable and electrically connected to the coil elements.

Description

【Technical field】 [0001] The invention relates to magnetic resonance imaging technology, in particular to a radio frequency coil assembly for magnetic resonance imaging. 【Background technique】 [0002] Magnetic resonance, also known as magnetic resonance imaging (Magnetic Resonance Imaging, MRI), spin imaging (spinimaging), nuclear magnetic resonance imaging (Nuclear Magnetic Resonance Imaging, NMRI), is another major advancement in medical imaging after CT. Since its application in the 1980s, it has developed at an extremely fast speed. The basic principle is to place the human body in a special magnetic field, and when the measured object is placed in the magnetic field, the hydrogen atoms in the body can be polarized. Use radio frequency pulses to excite the hydrogen nuclei in the human body, causing the hydrogen nuclei to resonate and absorb energy. After the radio frequency pulse is stopped, the hydrogen nucleus emits a radio signal at a specific frequency, and releas...
