摘要:
介绍了一种新颖伽马刀摆位床的控制方法.该方法通过BFGS算法建立由人体呼吸而产生的肿瘤位移的位移模型,用压电传感器采集患者呼吸信号,单片机系统接收到压电传感器发出的呼吸信号后会对步进电机进行控制,从而使摆位床按呼吸规律的逆向进行运动,仿真实验结果表明,该设计能够减少呼吸运动造成的肿瘤偏移幅度,为伽马刀摆位床的控制提供了一种新颖的方法和理论依据.
Abstract:
This paper introduces a novel control design of gamma knife positioning bed.Respiratory move-ments would inevitably cause tumor displacement. In this design，tumor displacement model produced by hu-man respiration was established through BFCS algorithm. Firstly , piezo sensor was used to collct respiratorysignal.Secondly, in order to make the positioning bed move by reverse respiration，after receiving the respira-tory signal，single chip microcomputer ( SCM) system would control stepping motor. The simulation experi-ment results showed that this design can reduce the influence of respiratory movements on the precision of ra-diotherapy，which produces a novel method and theoretical basis for the control of gamma knifepositioning bed.
