Abstract
The paper shows the possibilities of using a fluorine-containing liquid—the so-called dry water for the MRI of inanimate objects using the signal void imaging method. Examples of visualization of objects that cannot be immersed in ordinary water and other liquid media that can dissolve or spoil the object under study are presented. The possibilities of visualization of a radio engineering product immersed in dry water during its operation are shown. Namely, the coil, which itself is involved in the scanning process, is used to receive and/or transmit RF power. It is shown that the images of the medium surrounding the coil obtained in this case make it possible to construct sensitivity maps and B1 maps of this coil. The issues of optimization of scanning parameters based on information about the 19F NMR spectrum and measurements of relaxation times for a given liquid are discussed.
