Abstract: An imaging apparatus comprising: at least a first module comprising a trolley provided with a plate on one face of which rests a magnetic assembly intended to apply a main magnetic field in an analysis zone of a main housing of the magnetic assembly, the trolley additionally comprising two side walls supporting the plate via one of their edges, designated the upper edge; a second module of substantially parallelepipedal shape, supporting a set of electronic control elements, the console being, in particular, configured to be inserted between the side walls of the trolley; the console and the first module comprising means of identification, by the console, of the geometric and magnetic features of the magnetic assembly of the first module, the means of identification being integrated in connection means.

Abstract: This magnetic emission device includes an antenna and further includes a device configured to select one of a plurality of predefined portions of the antenna and to connect the selected portion to a current-generating device in order both to cause the current to pass through the selected portion of the antenna so as to radiate a magnetic field, and to prevent the current from passing outside of the selected portion of the antenna.
