Slicing Frequency Mixed Traveling Wave for 3D Magnetic Particle Imaging
Magnetic Particle Imaging is based on the nonlinear response of ferro- and superparamagnetic particles to magnetic fields . For imaging, a field free point (FFP) within a string magnetic gradient on the order of 1–5 T/m is moved through the sample. A new gradient system design allows performing dynamic imaging in a linear sampling scheme by using a traveling wave approach . We present an extension for doing 3D imaging using a traveling wave in combination with frequency mixing  and a sliced field of view (FoV). This approach provides the possibility of an arbitrarily large FoV in one direction without increasing the specific absorption rate (SAR) and allows the spatial encoding in the additional 2 dimensions.
