A device that uses infrared reflectometry for monitoring the respiratory waveform of small rodents during MRI was developed. This system uses a photoplethysmograph coupled to the animal by a light pipe to detect movements as small as 1.0 mm. This device can also be used for monitoring larger animals or for controlling respiratory-compensated or respiratory-triggered MRI.
开发了一种利用红外反射测量法在磁共振成像（MRI）期间监测小型啮齿动物呼吸波形的设备。该系统使用通过光导管与动物相连的光电容积描记器来检测小至1.0毫米的运动。此设备还可用于监测较大动物或控制呼吸补偿或呼吸触发的MRI。
