Technology Roadmap for Integration of Resonant Markers in MRI Compatible Instruments

Open MR scanners with an improved patient access are well-suited for minimal-invasive interventions. Considering that instruments like catheters appear hypointense in the MR image due to their signal-loss artefact, suitable visualization techniques like passive resonant circuits tuned to the Larmor frequency are required for generating a hyperintense change of the signal intensity. Within this paper various microsystems technologies for fabricating resonant markers will be compared in order to estimate their potential for a subsequent application.
