摘要
利用聚焦超声治疗肿瘤时,需要对治疗前后的图像进行对比以检验疗效。但由于呼吸运动会引起脏器移位从而导致图像改变,给图像的对比造成较大的干扰。为此,我们研究了一种利用呼吸传感器实现同步图像采集的方法。该方法包括硬件和软件两个部分的设计,硬件部分的功能主要是监测和处理呼吸信号,软件部分则根据采集到的呼吸信号的特征值,以控制图形采集卡进行同步图像的采集。动物实验的结果表明,该方法能够实现同步图像采集,从而有效消除呼吸运动的影响。
A method of sync-image capture using respiratory sensor is presented.The method includes the design of hardware and software.The function of hardware system is monitor and process the respiratory signal and the software system is responsible for controlling the image capture board to capture the sync-images according to the characteristic of the respiratory signals.The result of the animal experiments indicates that using this method can realize the capture of sync-image and can effectively eliminate the interference of the respiratory movement.
