| 目的 通过提高X射线的线质,降低医生和患者的受照剂量。方法 使用单片机控制技术,通过绝缘栅双极性晶体管(IGBT)对X射线高压发生器初级交流电进行检测调制,使X射线管仅在高能区产生X射线,从而减少X射线辐射。结果 显著地降低了管电流,有效地降低医生和患者的受照剂量。结论 本系统能有效地降低X射线管辐射,经检测适用于各种大、中型工频X射线设备的升级。 |

| Objective To decrease the amount of radiation that doctor and patient receives by increasing X-ray quality. Methods Using Singlechip Microcomputer technology,test and modulate AC(Alternating Current)from high voltage generator by IGBT.X-ray tube generates X-rays only at high energy area.Thus the amount of radiation decreases. Results The tube current decreases remarkably and the amount of radiation that doctor and patient receives decreases effectively. Conclusion the system can effectively decrease the amount of radiation and is widely applicable to the upgrade of all kinds of single phase X-ray units. |
