From: Validation of 3D echocardiographic volume detection of left atrium by human cadaveric casts
a) Human cadaveric left atrial silicone cast (on right) and its transformed agar-agar cast without left atrial appendage, b) 3D echocardiographic volume analysis of cast no. 4 by TomTec 4D LV-Function (true volume 43 ml, measured volume 42 ml) and by c) GE 4D LVQ (measured volume 43 ml), d) cast no. 5 by GE 4d LVQ (true volume 44 ml, measured volume 45 ml), e) 3D volume measurement by GE 4D LVQ of a balloon with borderline on the inner aspect (true volume 140 ml, measured volume 136 ml) and f) on the outer aspect (measured volume 188 ml)
