[Low-field magnetic resonance tomography with an iron-shielded resistive magnet].
As an alternative to costly MRI systems with superconductive magnets, first experiences with an iron-shielded resistive system (Tomikon BMT 1100, Bruker Medizintechnik--Rheinstetten) are reported. The magnetic field strength is 0.235 T, corresponding to a proton resonance frequency of 10 MHz. Our system is used mainly for research, the image quality being comparable with that of superconducting systems. Especially favourable is the low magnetic stray field of the self-shielding system. It allows unproblematic handling of patients in a clinical environment. Economic aspects are not discussed.
