Magntic Particle Imaging compatible ultrasound transducers
Magnetic Particle Imaging (MPI) is a novel tomographic method that enables real-time imaging of the distribution of magnetic nanoparticles in biological tissue with high sensitivity and spatial resolution.
A combination of this tracer-based procedure with a diagnostic and therapeutic ultrasound system offers the possibility to use anatomical and functional information simultaneously and to investigate exciting interactions.
Since strong, alternating magnetic fields are required for MPI imaging, a combination with a conventional ultrasound system is not easily possible. Induced eddy currents would lead to heating and thus to the direct destruction of conventional transducer components.
The focus of our research in this field is on the development of MPI-compatible ultrasonic transducers for diagnostic and therapeutic applications. Novel transducer components and geometries are used to ensure compatibility and to minimize mutual interference.
