Abstract:
A method for inspecting a product having nuclei that can be magnetically polarized by a static magnetic field, comprising the steps of:(a) providing at least one product having said nuclei, said product being enclosed in a container including an electrically conductive barrier at least partially surrounding said product;(b) providing a MR apparatus for inspecting said at least one product in said container, said apparatus having means for generating a static magnetic field, RF transmitting means and RF receiving means;(c) positioning said container in said MR apparatus for inspection;(d) exciting said product in said container with an RF magnetic field generated by said RF transmitting means of said MR apparatus, at least a substantial portion of said electrically conductive barrier being oriented transversely to an orientation of said RF magnetic field during excitation;(e) receiving by said RF receiving means an RF signal from said at least one product in said container, said RF signal being a result of said excitation of said at least one product by said MR apparatus;(f) processing and analyzing said received RF signal to determine data of said at least one product.
