【摘要】 为实现机械辅助血管介入治疗中导丝输送所受阻力的测量,针对导丝输送力信号测量和标定问题开展研究,提出了一种综合传感器位置信息的导丝输送力与传感器信号的标定方法。在此基础上,建立了导丝输送力测量系统并进行了输送力标定试验。实验结果表明,采用提出的标定方法较常规最小二乘法所获得的结果精度予以提高。更多还原

【Abstract】 In order to measure the resistance of the guide wire during the robot-assisted endovascular intervention,the measurement of transmission force and calibration of the monitoring signal were studied. A calibration method considering sensor position information was put forward. On this basis,a measuring system of the guide wire transmission force was established and calibrated. The experimental results showed that the accuracy of the proposed method was higher than that of the conventional least squares method.更多还原
