Abstract EN
Both respiratory and cardiac motions reduce the quality and consistency of medical imaging specifically in nuclear medicine imaging.
Motion artifacts can be eliminated by gating the image acquisition based on the respiratory phase and cardiac contractions throughout the medical imaging procedure.
Electrocardiography (ECG), 3-axis accelerometer, and respiration belt data were processed and analyzed from ten healthy volunteers.
Seismocardiography (SCG) is a noninvasive accelerometer-based method that measures accelerations caused by respiration and myocardial movements.
This study was conducted to investigate the feasibility of the accelerometer-based method in dual gating technique.
The SCG provides accelerometer-derived respiratory (ADR) data and accurate information about quiescent phases within the cardiac cycle.
The correct information about the status of ventricles and atria helps us to create an improved estimate for quiescent phases within a cardiac cycle.
The correlation of ADR signals with the reference respiration belt was investigated using Pearson correlation.
High linear correlation was observed between accelerometer-based measurement and reference measurement methods (ECG and Respiration belt).
Above all, due to the simplicity of the proposed method, the technique has high potential to be applied in dual gating in clinical cardiac positron emission tomography (PET) to obtain motion-free images in the future.
