The utility model relates to a radio frequency coil assembly for magnetic resonance scanning equipment and the magnetic resonance scanning equipment. The radio frequency coil assembly comprises a first coil structure and a second coil structure, the first coil structure can be worn on a scanning part of a detected object, and the size of the first coil structure can be matched with the size of the scanning part, so that the first coil structure is closer to and fits the scanning part, and magnetic resonance signals emitted by tissues can be received more efficiently; a higher image signal-to-noise ratio is obtained; the second coil structure is separated from the first coil structure and surrounds the outer side of the worn first coil structure, and a certain gap is formed between the second coil structure and the first coil structure, that is, the size of the second coil structure can be made to be larger, so that the device can adapt to detected objects with more body types, and the proportion of applicable people is increased; and moreover, the problem of claustrophobia of the detected object can be relieved, the comfort of the detected object is improved, and the use is more convenient.

The application relates to a magnetic resonance coil assembly. The magnetic resonance coil assembly comprises a first coil structure and a second coil structure, the first coil structure is provided with a first accommodating cavity for accommodating a scanning part of a detected object; the second coil structure is surrounded outside the first coil structure and has a gap with the first coil structure, the size of the first coil structure can be matched with the size of the scanning part, so that the first coil structure is closer to and fits the scanning part, and thus the magnetic resonance signal emitted by the tissue can be more efficiently received, and a higher image signal-to-noise ratio can be obtained; the second coil structure is arranged outside the first coil structure and has a certain gap with the first coil structure, that is, the size of the second coil structure can be larger, which can not only adapt to more detected objects of different body sizes and improve the proportion of applicable people, but also can relieve the problem of claustrophobia of the detected object, improve the comfort of the detected object, and be more convenient to use.

A radio frequency coil for magnetic resonance-based brain function detection, and a radio frequency detection system. In the radio frequency coil for magnetic resonance-based brain function detection, by controlling a gap between an I-shaped structure (10) and a first I-shaped assembly (11) and a gap between the I-shaped structure (10) and a second I-shaped assembly (12), a user under examination can see through the gap therebetween; and by adjusting the capacitance values of multiple first capacitive components, multiple second capacitive components, multiple third capacitive components, and multiple fourth capacitive components, a birdcage structure generates a uniform magnetic field. Thus, by widening the field of view of the detection coil, the technical problem in the prior art that users easily experience claustrophobia during examination is solved while the detection performance of the radio frequency coil is maintained.
