MR IMAGING METHOD AND MEDICAL DEVICE FOR USE IN METHOD

摘要

The invention relates to an MR imaging method for representing and determini ng the position of a medical device inserted in an examination object, and to a medical device used in the method. In accordance with the invention, the device comprises at lea st one passive oscillating circuit with an inductor and a capacitor. The resonance frequenc y of this circuit substantially corresponds to the resonance frequency of the injected high- frequency radiation from the MR system. In this way, in a locally limited area situate d inside or around the device, a modified signal answer is generated which is represente d with spatial resolution.
