一种用于小射野剂量分布扫描的探测器
摘要：
本实用新型公开了一种用于小射野剂量分布扫描的探测器，包括由套筒、平衡帽和尾柄密封连接形成的气密腔体，所述套筒包括在前的窄径部分和在后的宽径部分，所述尾柄设在所述宽径部分的尾端，并与所述套筒的宽径部分形成后腔室；所述平衡帽设在所述窄径部分的顶端，并与所述套筒的窄径部分形成电离室，所述电离室内径为1.5-2mm，所述电离室的灵敏空气体积为0.1-0.2cm3。本实用新型的探测器结构简单，体积小，易于密封，可保证良好的密封性，且漏电小，能量响应好，使用时扫描分辨率高，能准确检测剂量学关键指标。
摘要（英）：

The utility model discloses a detector for scanning of little launched field dose distribution, include the air -tight chamber body that forms by sleeve, balanced cap and caudal peduncle sealing connection, the sleeve is including in the front the narrow footpath subtotal wide footpath part after, the caudal peduncle is established the tail end of wide footpath part, and with telescopic wide footpath part forms the back cavity, balanced cap is established the top of narrow footpath part, and with telescopic narrow footpath part forms the ionization chamber, is the ionization chamber internal diameter 1.5 2mm, is the sensitive air volume of ionization chamber 0.1 0.2cm3. The utility model discloses a probe structure is simple, and is small, easily sealed, can guarantee good leakproofness, and it is little to leak electricity, and the energy response is good, and the scanning resolution is high during the use, can accurately detect dosage and learn key index.
