Figure 4.

Comparison of deep learning method (top row) and 3mensio (bottom row) in key anatomical features in five representative cases with similar results. First to fifth column: LVOT, annulus, STJ, LCH, and RCH, respectively. The yellow (DL method) and white (3mensio) curves around the aortic root means the contour identified by these methods. LVOT, left ventricular outflow tract; STJ, sinotubular junction; LCH, height of left coronary ostium; RCH, height of right coronary ostium; DL, deep learning.
