A novel myocardium segmentation approach based on neutrosophic active contour model.BACKGROUND AND OBJECTIVES
 Then, a neutrosophic active contour model (NACM) is proposed and the energy function is defined by the NS values. 
neutrosophic active contour model
The purpose of this study is to automatically detect myocardium region in left ventricle myocardial contrast echocardiography (LVMCE) images to help radiologists' diagnosis and further measurement on infarction size.


 The LVMCE image is firstly mapped into neutrosophic similarity (NS) domain using the intensity and homogeneity features. 
LVMCE
Echocardiographic studies are performed on 10 male Sprague-Dawley rats using a Vivid 7 system including 5 normal cases and 5 rats with myocardial infarction.
