Physiologging enables you to reproducible record time-stamped physio data via a dedicated protocol parameter to correct effects from physiological motion and noise in the measured fMRI images. - stored physio data fMRI analysis physiological signals 3 Effective Date: 21 JUN 2023| HOOD05162003358959 Unrestricted © Siemens Healthineers, 2023 Physiologging SIEMENS Healthineers What does it do? 1. During data acquisition, all signals are recorded by 3. With Physiologging you can access the data in an internal physiological sensors, such as respiratory easily accessible text data format. It is stored as log sensor, beat sensor or other sensors. files, that are simple tables with time stamps and signal values for further offline processing. 2. Together with the imaging data, the visual data is being recorded within the raw data files. 4. A compressed xml structure containing the physio curves and time-stamps is also embedded in an additional non-image DICOM file.
