Abstract

本实用新型涉及一种医用放射治疗射源装置结构，主要由屏蔽体、放射源台体、准直体组成，屏蔽体、放射源台体和准直体均为一球缺壳体，屏蔽体装置在放射源台体的外侧，准直体装置在放射源台体的内侧，放射源台体和准直体同心，而与屏蔽体不同心。本实用新型是一种结构简单轻便，成本低廉，大大节省屏蔽材料的医用放射治疗射源装置结构。

Description

一种医用放射治疗射源装置结构
技术领域
本实用新型涉及一种医用放射治疗装置，特别是一种医用放射治疗射源装置结构。
背景技术
一般医用放射治疗射源装置结构，屏蔽体、放射源台体、准直体是同心的。这样一来，无论在治疗时还是在非治疗时，在整个放射源台体外侧加上的屏蔽体的厚度是相同的，不但沉重而且由于使用许多屏蔽材料使得价格昂贵。特别是在使用C型开放式单侧支撑支架时，由于重量大，而且重心偏离单侧支撑支架过远，容易造成整个装备不稳定。
发明内容
本实用新型的目的在于提供一种结构简单轻便，成本低廉，大大节省屏蔽材料的一种医用放射治疗射源装置结构。
为实现上述目的，本实用新型采取以下设计方案：这种医用放射治疗射源装置结构，主要由屏蔽体、放射源台体、准直体组成，所述屏蔽体、所述放射源台体和所述准直体均为一球缺壳体，所述屏蔽体装置在所述放射源台体的外侧，所述准直体装置在所述放射源台体的内侧，所述放射源台体和所述准直体同心，而与所述屏蔽体不同心。
由于本实用新型采用以上技术方案，所述放射源台体和所述准直体同心，而与所述屏蔽体不同心。这样一来，在整个放射源台体外侧加上的屏蔽体的厚度是不相同的。在非治疗状态时，就可转动放射源台体，使集中放置于放射源台体内的放射源处于屏蔽体最厚的屏蔽位置，而其他部位就可减少屏蔽。特别是在使用C型开放式单侧支撑支架时，由于采用这种偏心结构，就可使射源装置的重心偏向单侧支撑支架，从而使整个装备稳定。同时既保证了屏蔽效果又大大减轻屏蔽材料的重量，使结构简单轻便，成本低廉，大大节省了屏蔽材料。
附图说明
下面结合附图对本实用新型作进一步说明。
图1为本实用新型示意图。
具体实施方式
如图1所示，本实用新型这种医用放射治疗射源装置结构，主要由屏蔽体1、放射源台体2、准直体3组成，所述屏蔽体1、所述放射源台体2和所述准直体3均为一球缺壳体，所述屏蔽体1装置在所述放射源台体2的外侧，所述准直体3装置在所述放射源台体2的内侧，所述放射源台体2和所述准直体3同心，而与所述屏蔽体1不同心。
由于本实用新型采用以上技术方案，所述放射源台体2和所述准直体3同心，而与所述屏蔽体1不同心。这样一来，在整个放射源台体2外侧加上的屏蔽体1的厚度是不相同的。在非治疗状态时，就可转动放射源台体2，使集中放置于放射源台体2内的放射源处于屏蔽体1最厚的屏蔽位置，而其他部位就可减少屏蔽。特别是在使用C型开放式单侧支撑支架时，由于采用这种偏心结构，就可使射源装置的重心偏向单侧支撑支架，从而使整个装备稳定。同时既保证了屏蔽效果又大大减轻屏蔽材料的重量，使结构简单轻便，成本低廉，大大节省了屏蔽材料。
以上仅为本实用新型的一个实施例，任何基于本实用新型的等同变换均在本实用新型的保护范围之内。
