Animal imaging with biosignals. (a) Axial MR image of the beagle at the plane of the attached EIT electrodes. (b) Time series of time-difference images at 11.25 kHz during mechanical ventilation. (c) Plot of the average pixel values of the ROI L inside the lung region. (d) Estimated respiration rate from the reconstructed images is well correlated with the ventilator setting. (e) Plot of the average pixel values of the ROI H inside the heart region, which is well correlated with the ECG signal. ECG-gating imaging was conducted to produce these results.
