Convolutional Neural Network for the Detection of End-Diastole and End-Systole Frames in Free-Breathing Cardiac Magnetic Resonance Imaging

Abstract EN

Free-breathing cardiac magnetic resonance (CMR) imaging has short examination time with high reproducibility.

Detection of the end-diastole and the end-systole frames of the free-breathing cardiac magnetic resonance, supplemented by visual identification, is time consuming and laborious.

We propose a novel method for automatic identification of both the end-diastole and the end-systole frames, in the free-breathing CMR imaging.

The proposed technique utilizes the convolutional neural network to locate the left ventricle and to obtain the end-diastole and the end-systole frames from the respiratory motion signal.

The proposed procedure works successfully on our free-breathing CMR data, and the results demonstrate a high degree of accuracy and stability.

Convolutional neural network improves the postprocessing efficiency greatly and facilitates the clinical application of the free-breathing CMR imaging.
