摘要
阐述了通过在C型臂X线机的球管侧和增强器侧分别安装2个激光器,利用激光形成的"十字交叉"进行预先定位的激光双定位系统方案,通过等效模型测量了定位误差并分析了产生误差的原因及缩小误差的方法。
A laser dual- positioning system available in c-arm X ray machine is introduced, which can perform advance positioning through the ＂cross shaped＂ laser beam formed by two sets of laser sets mounted respectively at both tube side and intensifier side of the c-arm. The positioning deviations measured in its equivalent model are presented, and the factors leading to these deviations are analyzed.
