[0053] During assembly, the RF coil 2 is positioned so that the protruding structure 22 is aligned with the first engaging groove 111 , and then the RF coil 2 is pushed so that the protruding structure 22 slides into the first engaging groove 111 from the opening thereof, and the RF coil 2 is pushed continuously until it is pushed to the preset position.

[0054] Based on the above embodiment, the second end of the RF coil 2 abuts against the bed board body 11 ; the bed board body 11 further has a second snap-in groove 114 , the second snap-in groove 114 is snap-connected with the baffle 4 , and the first end of the RF coil 2 abuts against the baffle 4 .

[0056] When assembling, attach Figure 1 As a reference, the RF coil 2 is pushed horizontally to slide along the first clamping groove 111 until the RF coil 2 abuts against the bed plate body 11, and then the baffle 4 is inserted into the second clamping groove 114 to fix the RF coil 2. With this arrangement, the scanning bed is easy to assemble and the coil can be easily installed in place.

[0057] On the basis of the above embodiment, the support groove 121 is an arc groove, such as Figure 2 As shown, with such a configuration, the groove wall of the support groove 121 can fit the patient's head more closely, which is beneficial to further improve the patient's comfort.

[0060] Preferably, the wire outlet hole of the male connector 6 is located on its vertical side wall. After the male connector 6 is vertically inserted into the second wire groove 113 on the female connector 7, the cable extends laterally. Such an arrangement effectively realizes a miniaturized design, which is conducive to opening a smaller second wire groove 113 on the bed board body 11 for burying the male connector 6 and the female connector 7.
