However, the gold standard for right ventricular quantification, cardiovascular magnetic resonance imaging (CMR), is not widely available, whereas widely used imaging techniques such as two-dimensional transthoracic echocardiography (2DE) are typically inaccurate due to the complex geometry of the right ventricle. This technology is an attention-based deep learning for cardiac right ventricular volume quantification using 2D echocardiography. To diagnose cardiac diseases and follow up response to treatment, doctors often need accurate measurements of the right ventricle, a core structure of the heart.
