Description

婴幼儿用核磁共振成像系统及其成像方法
技术领域
本发明涉及一种婴幼儿用核磁共振成像系统及其成像方法。
背景技术
核磁共振成像(MRI,英文全称:magnetic resonance imaging)系统常被用于医疗卫生领域,即利用人体组织中氢原子核(质子)在磁场中受到射频脉冲的激励而发生核磁共振现象,产生磁共振信号,经过电子计算机处理,重建出人体某一层面的图像的成像技术。
针对婴幼儿常见病症的核磁共振成像诊断,已经在医疗领域得到了越来越高的重视,而婴幼儿核磁共振成像普遍使用常规的核磁共振系统、CT、超声等手段,基于安全性和成像价值,核磁共振具有明显的优势。目前,市场上虽然出现了婴幼儿专用的核磁共振系统,但是在开放性及适用性上存在局限性,比如,婴幼儿被完全嵌入专用的核磁共振系统,对医生的观察造成影响,带来了一定的使用安全隐患;此外,针对新生婴幼儿核磁共振成像,传统的核磁共振系统存在噪音过大,电磁辐射能量的剂量难控制,没有完备的保温措施等不适用性。
发明内容
本发明提供一种婴幼儿用核磁共振成像系统及其成像方法,以解决对婴幼儿实施核磁共振成像时保温措施不兼容、婴幼儿无法根据医生指令调节身体姿势等问题。
为解决上述技术问题,本发明提供一种婴幼儿用核磁共振成像系统,包括底座、外壳、监护屏蔽罩、开放磁体、磁体座、工作平台以及保温箱,所述外壳的底部固定于底座上,所述外壳的顶部与所述监护屏蔽罩可翻转式连接;所述磁体座固定于所述底座上,所述开放磁体固定于所述磁体座上,所述开放磁体中设有一成像区域,所述工作平台固定于所述成像区域内,所述保温箱与所述工作平台活动连接,所述磁体座、开放磁体、工作平台及保温箱均设置于所述底座、外壳和监护屏蔽罩组成的空间内。
较佳地,还包括功放和谱仪。
较佳地,所述保温箱内设有射频接收线圈。
较佳地,所述开放磁体周围设有梯度线圈和匀场线圈。
较佳地,所述梯度线圈采用静音梯度线圈。
较佳地,所述监护屏蔽罩采用透明材料制成。
本发明还提供了一种婴幼儿用核磁共振成像方法,应用于如上所述的核磁共振成像系统,其步骤包括:
S1:将婴幼儿放置于保温箱内;
S2:将监护屏蔽罩关闭;
S3:调节保温箱内的温度以及相对于开放磁体的位置,将婴幼儿待成像部位置于成像区域内,进行核磁共振成像。
相比于现有技术,本发明提供的婴幼儿用核磁共振成像系统及其成像方法具有如下优点:
1.本发明通过优化的结构设计、特定的开放磁体布局以及专用保温箱和工作平台的设计,能够让放射科医生更精确、直观地调整和了解婴幼儿成像的位置、角度;
2.采用静音梯度线圈,降低噪音,恒定地维持婴幼儿所处环境的安静和舒适;
3.采用透明材料制成监护屏蔽罩,使医生及父母能够更直观的了解婴幼儿的检测全部过程,从而提供更好的用户体验;
4.通过使用开放磁体、优化的射频线圈设计及婴幼儿专用的序列设计,降低能量辐射的剂量。

具体实施方式
为了更详尽的表述上述发明的技术方案,以下列举出具体的实施例来证明技术效果;需要强调的是,这些实施例用于说明本发明而不限于限制本发明的范围。
本发明提供的婴幼儿用核磁共振成像系统,如图1至图4所示,包括底座10、外壳20、监护屏蔽罩30、开放磁体40、磁体座50、工作平台60以及保温箱70,当然,还包括核磁共振其他核心部件,此处不予赘述。具体地,所述外壳20的底部固定于底座10上,所述外壳20的顶部与所述监护屏蔽罩30可翻转式连接,使监护屏蔽罩30存在打开和关闭两种状态(具体参见图1和图4),取放婴幼儿时打开,进行核磁共振成像时关闭,具体地,所述外壳20中设有电磁屏蔽层(未图示),所述磁体座50中设有用于走线同时屏蔽电磁信号的传导板(未图示),当两侧的监护屏蔽罩30接触闭合时,在中间位置形成密封边31,所述监护屏蔽罩30与外壳20中的电磁屏蔽层、传导板接合,实现对核磁共振系统封闭的电磁屏蔽,为婴幼儿营造良好的环境;所述磁体座50固定于所述底座10上,所述开放磁体40固定于所述磁体座50上,所述开放磁体40中设有一成像区域,所述工作平台60固定于所述成像区域内,具体地,本实施例中,所述开放磁体40的上部为间隔设置的两个半圆形磁体,两个半圆形磁体间隔的中间区域即为成像区域;所述保温箱70与所述工作平台60活动连接,也就是说,所述保温箱70可在成像区域内相对于开放磁体40任意移动,包括水平方向、垂直方向以及绕垂直方向旋转,具体地运动方式可采取任意一种现有的运动方式,且运动方式并非本申请的重点,因此不予赘述;当然,所述保温箱70的温度可调;所述磁体座50、开放磁体40、工作平台60及保温箱70均设置于所述底座10、外壳20和监护屏蔽罩30组成的空间内。本发明通过优化的结构设计、特定的开放磁体40布局以及专用保温箱70和工作平台60的设计,能够让放射科医生更精确、直观地调整和了解婴幼儿成像的位置、角度,并使婴幼儿始终处于温暖舒适的环境中。

较佳地,所述梯度线圈采用静音梯度线圈设计,即在梯度线圈中设置真空隔绝层,从而降低成像过程中的噪音等级,保持整个成像过程中婴幼儿均处于安静、舒适的环境中。
较佳地,所述监护屏蔽罩30采用透明材料制成,在不影响监护屏蔽罩30本身的屏蔽效果的同时,使医生及父母能够更直观的了解婴幼儿的检测全部过程,以确定婴幼儿的状态,从而提供更好的用户体验。
另外,本发明还能通过使用开放磁体40、优化的射频线圈设计及婴幼儿专用的序列设计,降低能量辐射的剂量,使其更加适用于婴幼儿患者。
