Abstract

We applied back projection method and got a 2D image of the bottle as shown in Fig.1. Two separated bright area can be seen. Each spot is corresponding to the ¹H of water. Then we applied this technology to the contaminant detection in food. Two water bottles, one with a small aluminum ball of φ1.5 mm, the other without, were prepared. Figure 2 shows the comparison of the ¹H signal intensity between with an aluminum small ball and without. In case of the existing of the aluminum ball, one dip can be observed in the spectrum. At present we don´t use MPI technology, but MPI will be applied to the system to enhance the signal in the near future.
