Research offers new way to see inside solids - Researchers at Yale University have developed a new way of seeing inside solid objects, including animal bones and tissues, potentially opening a vast array of dense materials to a new type of detailed internal inspection. The technique, a novel kind of magnetic resonance imaging (MRI), creates 3D images of hard and soft solids based on signals emitted by their phosphorus content. The research, "quadratic echo MRI of solids," is published in the journal PNAS.
