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1-5，其为本发明实施例提供的便携移动磁共振***，其包括扫描主机5、移动底盘6和外壳1，扫描主机5固定在移动底盘6上，且位于外壳5内。
其中，移动底盘6包括平台101和设置于平台底部的行走轮机构；外壳1上设有对称的通孔，通孔设置在与扫描主机5扫描区域对应的位置。
扫描主机内设置有磁体103、冷却***105、谱仪106、梯度***电源107、梯度***108、温控***109、***电源110；其中磁体103固定在平台101的中间，为永磁磁体；冷却***105、谱仪106、梯度***电源107、梯度***108、温控***109和***电源110固设在磁体103周围，这样布局合理，结构更紧凑。其中，温控***109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。冷却***105用于将磁共振***扫描工作时所散发出来的热量带走，保持磁体温度恒定，从而保持磁场恒定不变。谱仪106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***108用于磁共振***扫描时梯度信号的发射，使***产生梯度磁场。梯度***电源107主要用于对梯度***108供电，保证梯度***108能够正常 工作。***电源110用于为整套磁共振成像***进行供电。
进一步地，为了屏蔽外界电磁信号对磁体103成像干扰，扫描主机1还包括屏蔽装置102；磁体103安装在屏蔽装置102内；屏蔽装置102上设有开孔，该开孔与外壳1上通孔对应，以便于患者进出，进行扫描检测。屏蔽装置102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)。
进一步地，为了便于调整扫描主机5的高度，适应不同的病床，扫描主机5还包括升降装置104，其安装于屏蔽装置102的外侧，固定于移动底盘的平台101上，并与磁体103固定连接。
优选地，磁体103为双侧立柱式框架结构，两侧具有对称的立柱，如图3所示。该结构磁体轭铁导磁率高，从而在相同磁场下可以将磁体结构紧凑重量轻，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长生磁场干扰。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。
立柱式结构的磁体103，也便于升降装置固定，因此优选地，如图5所示(为了更好表示升降装置104与磁体的103安装结构，图5中将屏蔽装置102隐藏。)升降装置104包括升降杆，升降杆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。优选地，升降支架111为直角三角形支架，升降支架的两个直角面分别与立柱和升降杆的端部固定连接；三角形的斜边面可以起到支撑作用，使得升降装置运动更稳定。
为了便于加工，同时也利于安装支撑其他成像部件，使得结构紧凑，屏蔽装置102为箱式结构，如图2所示，梯度***电源107和梯度***108位于屏蔽装置的顶部，冷却***105、谱仪106、温控***109和***电源110位于屏蔽装置102的两侧。
进一步地，该***还包括病床3，病床3包括延长板4，延长板4可伸入外壳1上的通孔，进入扫描主机5的扫描区域内。
进一步地，该***还可以包括一扫描电脑，与扫描主机5电连接，以观察扫描图像。
本发明的便携移动磁共振***，使用时，首先将扫描主机5通过移动底盘6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，通过升降柱104的上下移动调节扫描主机5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4一起通过通孔进入磁体103扫描空间，并使待***位位于扫描空间的中间部位。然后操作扫描主机对病人进行核磁成像扫描，扫描完成后，在扫描电脑上直接读取病人2病灶图像进行现场诊断，方便快捷。
本发明实施例提供的便携移动磁共振***，具有以下有益效果：
1、扫描主机底部设有移动底盘，便于移动。
2、永磁磁体外侧安装有屏蔽装置，用于屏蔽磁共振扫描时外界信号干扰，谱仪、射频***、温控***以及扫描计算机等核磁扫成像主要功能部件均布安装于屏蔽装置外侧，构成磁共振成像***的主体结构，布局合理，结构紧凑。
3、磁共振成像***的主体结构与升降***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、永磁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***，通过优化组合，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。
