The proton density maps were calculated from the set of MSE and TOMROP images (i.e. M0(T2) and M0(T1), respectively). They showed that the locular tissue had the highest proton density, followed by the outer pericarp, radial pericarp, placenta and core. The mean values ofM0(T2) for these tissuewere 0.85±0.02, 0.83±0.02, 0.78±0.03, 0.73±0.03 and 0.71±0.03, respectively. No distinct variations were observed with ripeness.
