A new method for deriving pulse rate from PPG obtained from ambulatory patients is presented. The method employs Ensemble Empirical Mode Decomposition to identify the pulsatile component from noise-corrupted PPG, and then uses a set of physiologicall

Image quality in non-gated versus gated reconstruction of tongue motion using Magnetic Resonance Imaging

Autor: Alvey, C, Orphanidou, C, Coleman, J, McIntyre, A, Golding, S, Kochanski, G

Purpose: The use of gated or ECG triggered MR is a well-established technique, and developments in coil technology have enabled this approach to be applied to areas other than the heart. However, the image quality of gated (ECG or cine) versus non-ga

Spectral fusion for estimating respiratory rate from the ECG

Autor: Orphanidou, C, Brain, O, Feldmar, J, Khan, S, Price, J, Tarassenko, L, IEEE

A new method for extracting respiratory signals from the electrocardiogram (ECG) is proposed. The method performs AR spectral analysis on heart rate variability and beat morphology information extracted from the ECG and identifies the closest matched

Testing the ecological validity of repetitive speech

Autor: Kochanski, G, Orphanidou, C

Can one trust experiments conducted with repetitive speech to represent normal language behaviour? We compare the spectra of repetitive productions of phrases with the same phrases read from a randomised list. We use a data-driven spectral distortion
