Description

医疗诊断用X射线探测器 技术领域
本发明涉及一种X射线探测器，尤其涉及一种可用于医疗诊断用X射线探测器。
背景技术
X射线诊断系统作为一种影像诊断学检查系统，其已经被广泛的用来对人体进行检查，形成影像资料，便于医生进行诊断。X射线探测器作为X射线诊断系统中非常重要的单元，直接影响着系统诊断影像的质量。
通常，在X射线诊断过程中，X射线探测器可通过其中设置的感光元件，如玻璃面板来感应穿过诊断对象的X射线，并通过数据采集模块对感光元件感应到的X射线信号进行数据采集后输送给控制板，以便于后续继续对采集到的数据进行成像处理。
在现有的一些X射线探测器中，其设置有支撑板(或称背板或冷板)、设置于支撑板上的X射线阻挡件(Beam Stopper)、铝板、设置于铝板上的黑色乙烯膜及感光元件。感光元件设置于铝板上并与铝板紧密贴合，从而通过铝板对感光元件起到静电移除的作用。
然而，在现有的设计中，由于需要面板与铝板紧密贴合，从而对铝板的加工精度要求就非常高，这增加了加工的难度和制造成本。而且，此种结构也不能很好的解决外部的震动或冲击导致玻璃面板变形和碎裂的问题。
已经有一些其他的尝试来解决上述问题。比如，不设置铝板而在玻璃面板的背面喷涂导电材料来对感光元件起到静电移除的作用。然而，喷涂材料可会对环境造成污染，且喷涂的过程需要很好的控制，这增加了探测器的制造过程的复杂性，从而对制造造成不利的影响。
所以，需要提供一种新的诊断用X摄像探测器，其可以很好的确保 探测器具有较高的、稳定的性能的同时且降低制造难度和成本。
发明内容
本发明一个实施例提供了一种医疗诊断用探测器。该诊断用探测器包括感光元件、X射线阻挡元件、支撑板及导电衬垫。感光元件用来感应X射线。X射线阻挡元件用来阻挡穿过所述感光元件的X射线。支撑板设置于X射线阻挡元件的下方用来支撑所述感光元件。导电衬垫设置于所述感光元件和所述支撑板之间与所述感光元件相贴合。
附图说明
通过结合附图对于本发明的实施例进行描述，可以更好地理解本发明，在附图中：
图1为本发明探测器一个实施例的分解示意图；
图2为本发明探测器的一个实施例的装配示意图；及
图3到图4为本发明探测器导电衬垫的不同实施例的安装示意图。
具体实施方式
以下将描述本实用新型的具体实施方式，需要指出的是，在这些实施方式的具体描述过程中，为了进行简明扼要的描述，本说明书不可能对实际的实施方式的所有特征均作详尽的描述。应当可以理解的是，在任意一种实施方式的实际实施过程中，正如在任意一个工程项目或者设计项目的过程中，为了实现开发者的具体目标，为了满足系统相关的或者商业相关的限制，常常会做出各种各样的具体决策，而这也会从一种实施方式到另一种实施方式之间发生改变。此外，还可以理解的是，虽然这种开发过程中所作出的努力可能是复杂并且冗长的，然而对于与本实用新型公开的内容相关的本领域的普通技术人员而言，在本公开揭露的技术内容的基础上进行的一些设计，制造或者生产等变更只是常规的技术手段，不应当理解为本公开的内容不充分。
除非另作定义，权利要求书和说明书中使用的技术术语或者科学术语应当为本实用新型所属技术领域内具有一般技能的人士所理解的通常意 义。本实用新型专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“一个”或者“一”等类似词语并不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现在“包括”或者“包含”前面的元件或者物件涵盖出现在“包括”或者“包含”后面列举的元件或者物件及其等同元件，并不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，也不限于是直接的还是间接的连接。
图1所示为本发明医疗诊断用探测器10的一个实施例的分解示意图。图2所示为本发明探测器10的一个实施例的装配示意图。在本实施例中，探测器10的结构仅示意性的，在不同的应用中，探测器10还可包括其他结构或元件(未图示)来完成探测器的探测功能。
如图1到图2所示，探测器10设置有支撑板11、X射线阻挡件12、导电衬垫13和感光元件14。支撑板11设置于探测器10的下方，从而对探测器10的其他元件或结构起到支撑作用。在非限定示例中，背板11由金属材料制成，其也可称为背板或作为冷板使用。
X射线阻挡件12设置于支撑板11的上表面(未标注)，也即支撑板11设置于X射线阻挡件12的下方。在非限定示例中，X射线阻挡件12通常包括铅材料或钨材料。在探测器10探测过程中，该X射线阻挡件12可用来阻挡穿过感光元件14的X射线，避免X射线进一步穿过支撑板11而进入到外部环境中造成不利的后果。
导电衬垫13设置于X射线阻挡件12上。感光元件14，可用来感应穿过诊断对象的X射线，其设置于导电衬垫13上，从而导电衬垫13位于感光元件14和X射线阻挡件12或背板11之间。在本发明实施例中，导电衬垫13为柔性衬垫，感光元件14可包括玻璃面板。这样，玻璃面板14可较容易的设置于导电衬垫13上且与其贴合，从而导电衬垫13可起到接地或静电移除的作用。同时，由于导电衬垫13具有一定的弹性，其可对外部的震动或冲击起到缓冲作用而保护玻璃面板不受损伤。在一些示例中，导电衬垫13可为任何合适的衬垫而使用在本发明实施例中。
在本实施例中，导电衬垫13设置于X射线阻挡件12上。在非限定示例中，导电衬垫13也可设置于支撑板11上从而位于X射线阻挡件12与支撑板11之间。
在一定的应用中，如图1所示，导电衬垫13为一整体结构，其设置于玻璃面板14和支撑板11之间。本发明实施例就可选择性的设置或不设置有黑色的乙烯膜15来吸收部分穿过玻璃面板14的X射线。在一个非限定示例中，本发明实施例可不设置黑色的乙烯膜15，比如导电衬垫13可设置为黑色，这样，不仅确保了玻璃面板的安全而且节省了成本。
在其他示例中，导电衬垫13可设置为条状。在一个示例中，如图3所示，黑色乙烯膜设置于X射线阻挡件12上，导电衬垫13以条状形式设置于乙烯膜的三个边上，从而设置玻璃面板于该结构上。在另一示例中，如图4所示，根据不同的需要，导电衬垫13也可以条状形式设置于乙烯膜的四个边上。
在本发明实施例中，探测器10设置有具有一定柔性的导电衬垫13于玻璃面板14和支撑板11之间。相较于传统的使用铝板的结构，本发明结构可以不需要再使用铝板，这样就降低了加工难度，且节省了成本。同时，由于导电衬垫13的使用，在一定的应用中，也可以省掉使用黑色乙烯膜而进一步节省了成本。另外，导电衬垫13设置于玻璃面板14和支撑板11之间，由于其本身具有一定的柔性，便可对外部冲击或震动起到缓冲和消减的作用，从而可以更好的保护玻璃面板14不受损伤。进一步的，由于导电衬垫13的使用，使得探测器10的结构得到简化，便于制造。
虽然结合特定的实施例对本发明进行了说明，但本领域的技术人员可以理解，对本发明可以作出许多修改和变型。因此，要认识到，权利要求书的意图在于覆盖在本发明真正构思和范围内的所有这些修改和变型。
