Summary of ATMT steps. a) Cross-sectional view of an explanted heart submerged in a cylindrical water bath. c) Application of upper and lower intensity thresholds to eliminate bulk of signal associated with the water bath. c) By successively removing extra-cardiac features, the 3D heart voxels are isolated. d) To isolate the left ventricle an irregular region encompassing the right ventricle is manually identified for removal.
