Embodiment 1

[0073] figure 1 It is a magnetic resonance receiving coil assembly of the present invention, which is a receiving coil assembly for interventional magnetic resonance, including a coil body 1 , a bracket 2 and a base 3 , and the base 3 is used to place the coil body 1 and the bracket 2 .

[0074] The coil body 1 includes a detachable upper coil 11 , a lower coil 12 and a locking mechanism 13 . There are two locking mechanisms 13 , which are respectively located at the joints of the upper coil 11 and the lower coil 12 . The upper coil 11 and the lower coil 12 are electrically connected through electrical connectors. The upper coil 11 includes an upper coil housing and electrical components accommodated therein; the lower coil 12 includes a lower coil housing and electrical components accommodated therein. The materials of the upper coil housing and the lower coil housing are engineering plastics polyamide.

[0075] The bracket 2 is used to provide support for the patient's ne...

Embodiment 2

[0091] Figure 5 It is another magnetic resonance receiving coil assembly of the present invention. In this embodiment, the bracket 2 is divided into two parts, namely a first bracket 21 and a second bracket 22 . Both the first bracket 21 and the second bracket 22 are fixedly installed on the fourth base 34 . The middle part of the fourth base 34 is provided with a strip-shaped groove for accommodating the first base 31 , the second base 32 and the third base 33 . The first bracket 21 and the second bracket 22 are respectively located on two sides of the bar-shaped slot. All the other components and conditions are the same as in Example 1.

[0092] Compared with Embodiment 1, the height of the support 2 in this embodiment can be lower, and the coil body 1 will not be restricted by the support when moving in the X direction, so a larger moving distance in the X direction can be obtained. When the coil main body 1 needs to be taken out from the first base 31, the support 2 d...

Description

technical field [0001] The invention relates to an interventional magnetic resonance receiving coil assembly and magnetic resonance equipment, in particular to a movable interventional magnetic resonance receiving coil assembly and magnetic resonance equipment. Background technique [0002] A magnetic resonance system is a device used for medical imaging diagnosis, which can provide clear and accurate images of human anatomy. The main principle of the magnetic resonance system is as follows: After the atomic nuclei in the magnetic field are excited by a short-term electromagnetic wave of a certain frequency, they emit an electromagnetic wave signal with a frequency equal to the excitation frequency. This signal is collected by the receiving coil and sent to a signal processing device (such as a computer). Image is formed after processing. [0003] In minimally invasive interventional surgery, it is necessary to pre-scan the surgical site with nuclear magnetic resonance in o...
