Objective: to study the effects of respiratory movement frequency and scanning time on the image results in the treatment of lung cancer by stereotactic radiotherapy.
目的：研究立体定向放射治疗肺癌中呼吸运动频率与图像扫描时间对靶体积定位成像结果的影响。

With this system, a study has been made on the correlation between respiratory impedance and dynamic compliance of rabbit, and oscillatory frequency.
利用这一系统，研究了家兔的肺阻抗和动态顺应性与振荡频率的依赖关系。

Respiratoryfrequency and arterial pressure before and after stimulating were monitored and recorded with thorax skin linking convertor and femoral arterial cannulation.
