A novel floating table enhances interventional magnetic resonance (MR) angiography by enabling real-time tracking of visualized catheters during procedures. This setup improves usability and flexibility for MR imaging-guided interventions.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Biomedical Engineering

Background:

  • Interventional magnetic resonance (MR) angiography requires precise instrument visualization and real-time imaging.
  • Current setups may face limitations in tracking actively visualized instruments during complex procedures.

Purpose of the Study:

  • To evaluate a novel floating table integrated into an interventional MR angiography setup.
  • To assess the system's capability for actively visualized catheters and biplanar real-time image fusion.

Main Methods:

  • A floating table was incorporated into an interventional MR angiography system.
  • The setup was tested through catheterization procedures in eight pigs.
  • Actively visualized instruments and biplanar MR imaging were utilized.
