An x-space magnetic particle imaging scanner.
Rev Sci Instrum
This was a practical paper describing the hardware and firmware of our MPI scanners.
Magnetic particle imaging (MPI) is an imaging modality with great promise for high-contrast, high-sensitivity imaging of iron oxide tracers in animals and humans. In this paper, we present the first x-space MPI hardware and reconstruction software; show experimentally measured signals; detail our reconstruction technique; and present images of resolution and "angiography" phantoms.
