| 摘要 |
The invention relates to a method for removing oscillatory artefacts caused by pressure waves in a fluid-filled transluminal catheter (4) from invasive blood pressure measurement data (2), including the steps of setting up a model (16) for the measurement data (2), fitting the model to the measurement data (2), identifying the model components (24, 26), representing the oscillatory artefact, and removing the oscillatory artefact from the measurement data. The invention also relates to a respective device for acquiring and correcting invasive blood pressure measurement data.
