From: Automatic echocardiographic anomalies interpretation using a stacked residual-dense network model
Example of the echocardiogram annotation process by experts to develop an AI model that can detect cardiac septal defects prenatally and postnatally. The cardiac chamber region is marked with white (right atrium [RA], left atrium [LA], right ventricle [RV], and left ventricle [LV]), whereas the defect area is marked with red. a Echocardiogram annotation of cardiac septal defect postnatally. b Echocardiogram annotation of cardiac septal defect prenatally
