X - ray collimator subsystem is the important part of x - ray machine, and its main function is confine the scope of x - ray beam, to reduce the radiation harm to patients ; another function is realizing the multi - scope exposure on one film working with the film motion and shielding system
X光機限束器子系統作為x光機的重要組成部分，其主要用於對x光束的照射范圍進行限定，以減少對患者的輻射，以及配合點片系統實現對x光膠片的多分片功能。 -
The whole - body gamma knife system is a kind of non - invasive medical instrument by using co - 60 as the gamma ray source. according to geometrically focusing theory, the gamma knife system can precisely focus in spirals 30 beams of gamma rays from different directions to a target through a collimator. by the collimator s direction, the predetermined lesion will be under radiation in heavy dose and subsequently be destroyed completely
體部伽瑪刀是利用能產生伽瑪射線的鈷60作為放射源，根據幾何聚焦原理，將30束伽瑪射線從不同方向和位置通過準直后經一個固定的軸旋轉聚焦到焦點，形成品質優良的劑量區，將腫瘤組織置於該高劑量區中，即可在預定時間內將病變組織摧毀，體表和焦點以外的正常組織僅受到瞬時照射而基本上不受損傷。 -
Firstly, we compared the domestic with the foreign products, analyzed the advantages and disadvantages of existing domestic products ; to reduce patients ray radiation, facilitate the operation and enhance the level of automation, at the same time, considering the goal of the sets, we made function goal of collimator subsystem
首先，在對比國內外產品的的基礎上，對國內的現有產品的優缺點進行了分析，結合整機的設計目標，以減少對患者的輻射、便於醫護人員操作和提高自動化水平為目標，確定了限束器子系統的功能目標。
