[Research Progress of Automatic Right Ventricle Segmentation Based on Cardiac Cine Magnetic Resonance Image].

Heart diseases seriously threaten people’s health.More and more functional evaluation of cardiac right ventricle has been considered in the clinical diagnosis in addition to the classical functional evaluation of cardiac left ventricle.It is very important to evaluate the functional parameters of right ventricle in clinical heart disease diagnosis,especially when the ejection fraction of left ventricle is very low.Right ventricular segmentation is needed for the functional evaluation.However,right ventricular segmentation has been difficult due to its thin myocardium,complex structure and significant individual variability.Cine cardiac magnetic resonance image is a golden standard in clinical functional evaluation of cardiac ventricle.In the present paper,we summarize the classic segmentation approaches,evaluation methods and their development,which can help the researchers in the related field have a quick and basic understanding to the right ventricle segmentation.
