MR compatible spirometer is needed for (i) monitoring of anaesthetized patient and (ii) sequence synchronization and/or image reconstruction to avoid motion artifacts. We present an MR compatible spirometer which aims at measuring patients air flow and lung volume in order to extract motion information. The proposed sensor could be connected to the respirator in order to monitor patients during MRI examination. Spirometer is well correlated to internal displacement extracted from the images series, although a time delay appears due to the external position of the sensor.
