4D echocardiographic system for wall motion and cardiac parameters quantification

We propose a system for 4D reconstruction, visualization, measurements and quantification of cardiac parameters. The system is connected with a conventional 2D ultrasound machine via video signal. Images are acquired and registered with electromagnetic position sensor readings and ECG signal readings. Volume reconstruction and volume visualization of the heart is done after acquisition. 4D cardiac parameters are calculated after segmentation of the desired cardiac ventricle such as left ventricle chamber. Cardiac parameters such as 3D surface area, 3D maximum area, 3D minimum area, 3D average volume and ejection fraction ratio are quantified along ECG cycles. Cardiac wall motion deformation measurements are quantified and color mapped to show the contractility of different wall segments which indicate cardiac abnormality.
