Figure 1

The delineations of the ischemic area made by the physicians and by EXINI for one of the patients. The upper row shows the stress (a) and rest (b) polar plots as well as the difference rest-stress plot (c). The second row shows the delineation made by EXINI (d), the delineations made by the 11 physicians without (e) and with (f) suggestion of the delineation provided by EXINI for stress polar plots. The third and forth rows show the same delineations for rest polar plots (g, h, i) and difference rest-stress plots (j, k, l). The physicians were able to choose between stress, rest or difference polar plots for their delineations.
