附图说明
通过阅读下文优选实施方式的详细描述，各种其他的优点和益处对于本领域普通技术人员将变得清楚明了。附图仅用于示出优选实施方式的目的，而并不认为是对本发明的限制。而且在整个附图中，用相同的参考符号表示相同的部件。在附图中：

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
参见图1-6，其为本发明实施例提供的分离式便携移动磁共振***，包括主体柜1、控制柜6，主体柜1和控制柜6之间通过电缆连接。
主体柜1包括移动底盘7，磁共振扫描主机及外壳5。移动底盘7包括平台101和设置于平台底部的行走轮机构105；磁共振扫描主机固定于平台101上，位于外壳5内；外壳5上对称的设有通孔501，通孔501设置在与磁共振扫描主机扫描区域对应的位置，以便于患者通过，进入扫描。此外，外壳5上 还设有观察窗502，便于观察。
控制柜6包括柜体601，柜体601内设置有若干层架602，层架602上分别设置有各控制部件，包括谱仪、射频装置、梯度装置、温控装置和***电源等；柜体底部设有若干滚轮603，以便于移动。其中，温控装置用于对磁体103进行保温加热，使磁体103温度恒定保持磁场强度不变。谱仪用于磁共振***扫描序列信号的发射接收及信号处理，是磁共振成像的关键部件。梯度装置用于磁共振***扫描时梯度信号的发射，使***产生梯度磁场。***电源用于为整套磁共振成像***进行供电。
进一步，如图2-4所示，磁共振扫描主机包括磁体103、屏蔽装置102；磁体103安装在屏蔽装置102内；屏蔽装置102上设有开孔，该开孔与主体柜外壳上通孔501对应，从而保证患者可以进入进行扫描成像。
屏蔽装置102设置在磁体103的外侧，可以屏蔽外界电磁信号对磁体103成像干扰。同时屏蔽装置102内还安装有其它成像工作部件，起到对磁共振成像***的支撑安装作用，屏蔽装置通常由导电良好的金属材料制作而成(例如镀锌钢板、不锈钢板或铜板等)，其结构可以为薄壳箱式结构。
其中，磁体103为双侧立柱式框架结构，两侧具有对称的立柱。该结构的磁体轭铁导磁率高，从而在相同磁场下，磁体结构可以更紧凑，而且重量轻，能够满足磁共振***便携移动使用要求。又因该结构磁体轭铁导磁率高，从而磁体103外侧所通过磁力线很少，不会对其它设备正常工作产生磁场干扰。同时对称布置双立柱磁体结构稳定刚性强，能够保证在磁体进行升降过程中不会发生变形影响磁体性能。
进一步地，为了便于调整，适应不同高度的病床，磁共振扫描主机还包括升降装置，其安装于屏蔽装置102的外侧，固定于移动底盘101的平台上，并与磁体固定连接。升降装置包括升降杆104，升降杆104底部固定于移动底盘的平台101上，其端部设有升降支架111，升降支架111固定连接于磁体的立柱。
为了更好的与磁体103连接，使得***升降更稳定，优选升降支架111为“├”型支架，“├”型支架的竖部与磁体的立柱固定连接，横部固定于升降杆104的端部，为了起到更好的支撑作用，竖部和横部之间还设有若干支撑肋条。升降杆104共有4根，对称的布置在屏蔽装置102四周。
这样通过移动底盘7带动可以实现磁共振成像***的灵活移动，并且通过对称布置升降装置的同步升降运动实现磁共振成像***的升降运动，便于调整。
进一步地，主如图5-6所示，体柜1和控制柜6的外侧均设有挂接装置8，可彼此挂接一起。这样能够使便携式移动磁共振***的空间适应性更强，在空间相对狭窄的病房内可以将磁共振主体柜1与控制柜6脱离使用，只需将磁共振主体柜1移动到病床3旁对病人2进行扫描检查。扫描检查结束后将磁共振主体柜1的挂接装置8与控制柜6的挂接装置8连接，使磁共振主体1与控制柜6挂接为一体，通过磁共振主体1移动同时拖动控制柜6进行移动。
进一步地，为了保证电气安全，主体柜1和控制柜6之间连接有电缆拖链9，电缆布置于电缆拖链9内。
进一步地，本发明实施例的分离式便携移动磁共振***还包括病床3，病床包括延长板4，延长板4可伸入所述主体柜1外壳上的通孔，进入扫描主机5的扫描区域内。
本发明的分离式便携移动磁共振***，使用时，首先将主体柜1通过其移动底盘7移动到需要做检查病人2的病床3旁。再将病人2在其病床3上向上移动一部分，使其需要做检查的部位探出病床3一定距离，同时将延长板4插放到病人2身体下方，用于支撑病人2探出病床部分身体。调整好病人检查***后，调节控制柜6内升降装置的控制装置，通过升降柱104的上下移动调节磁共振扫描主机的扫描空间高度，以适应不同病人病床3高度，使病人需要扫描部位位于设备扫描空间中间位置。然后向前移动病床3，使病人2随延长板一起通过通孔502进入磁体103扫描空间，并使待***位位于扫描空间的中 间部位。然后操作磁共振扫描主机对病人进行核磁成像扫描，扫描完成后直接读取病人2病灶图像进行现场诊断，方便快捷。
本发明实施例提供的分离式便携移动磁共振***，具有以下有益效果：
1、通过设置主体柜与控制柜，将磁共振扫描主体与控制***部分分离，分别安置于主体柜和控制柜内，这样不仅能够减轻磁共振主体部分的重量，便于移动，有更好的空间适应能力；同时也可以降低磁共振扫描时各控制部件工作噪声对病人的影响。
2、磁体外侧安装有屏蔽装置，可以屏蔽磁共振扫描时外界信号干扰。
3、磁共振成像***的主体部分与升降装置进行连接，升降装置安装于移动底盘上，能够调节磁共振主体结构的高度，适应不同病床扫描高度。
4、磁体采用框架式结构，还可以增加导磁性能，不仅提高磁场强度，还增加了磁体结构的稳定行，从而保证磁体升降不会变形，提高磁体性能降低磁体重量。
本发明的便携移动磁共振***结构紧凑、重量轻且能够便携移动，可以将其移动到病人病床旁边对病人进行扫描检查，可以最大化降低病人移动，特别适合刚刚做完手术不适宜移动病人检查，不会因病人移动而产生其它不必要的伤害。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
