Fig. 1 MPI for high-contrast tracer imaging . (a) MPI scans with/CT overlay of two SPIO vials (at 1 and 2.8 mm deep) shows no signal change with depth. (b)…

(1) where I is the transmitted beam intensity, I 0 is the incident beam intensity, and x is the thickness of the medium. The mass attenuation coefficient, μ, expressed in…

(1) In this, and the following equations, it is important to note that we are dealing with three-dimensional vectors that describe the resulting magnetic force, as well as the magnetic…
