β¦ Synopsis
One-dimensional magnetic resonance projections of pickled olives were acquired while they were travelling on a conveyor belt which passed through a 2-tesla NMR magnet and a 150-mm imaging coil. The projections were used to distinguish between pitted and non-pitted olives. The e β ect of fruit position in the coil was tested and coil end e β ects were noticed when projections were generated under dynamic conditions. Sorting of 300 pitted and non-pitted olives at various belt speeds was tested. ClassiΓcation errors (pitted olives classiΓed as non-pitted and vice versa) were 4Γ3, 4Γ7, 2Γ3 and 4Γ0% at 0, 5, 15 and 25 cm s~1 belt speeds, respectively.
