Flow chart for automatic segmentation algorithm. Flow chart of the automatic Segment MaR algorithm from user input to segmentation result. Step 1) shows the user interface for user input, step 2) shows the intensity histogram for a short axis slice and the estimated intensity distributions for normal myocardium and MaR, step 3) shows the MaR probability function in black and the estimated intensity distributions in red, step 4) shows the sector based bulls eye plot of MaR probability, with bright colors indicating high probability of MaR, in step 5) the MaR region of connected sectors fulfilling the regional criteria is marked in red and in step 6) the interpolated shape of the MaR region is marked in red and finally in step 7) the MaR region is shown in red in a short axis view.
