… ( t ) where ρ ˆ ( x ) is the “native” MPI image of nanoparticle distribution, x s (t) is the instantaneous
position of the FFP, and x s ( t ) is the instantaneous velocity of the FFP. Here we define …

… tracer H sat [A/m], the gradient field strength G [A/m/m] and the FFP slew rate x' s (t) [m/s].
The product Gx' s (t) [A/m/s] is simply the slew rate of the field used to excite the sample. …

Magnetic particle imaging is an emerging tomographic technique with the potential for
simultaneous high-resolution, high-sensitivity, and real-time imaging. Magnetic particle imaging is …

… (b) By applying an RF pulse with carrier frequency ω s and bandwidth BW, the regions with
… would be excited by a band-selective RF pulse with ω s = −20 ppm and BW = 10 ppm. Similar …

… SJ Connolly's scholarly and wide-ranging study examines these developments and sets
them in their historical context. The Ireland that emerges from his lucid and penetrating analysis …

… and we see that MPI’s bandwidth requirements increase linearly with nanoparticle properties
, gradient strength , and scanning rate [see Fig. 7(a)]. Evaluating the FWHM with realistic …

… Often the peak-magnitude limitations on one’s RF amplifier constrain the selective pulse
one may use. For example, the peak amplitude of a fixed-duration sine pulse increases linearly …

… The z frames (5.76 s per frame) are acquired at 2 mm increments, allowing for the stitching
required … by the fitting of M(H) data to a Langevin function (following Chantrell’s method (27)). …

Image-guided treatment of cancer enables physicians to localize and treat tumors with great
precision. Here, we present in vivo results showing that an emerging imaging modality, …

… rate of 15 frames/s for ∼100 s. A volume of 50 µl Halo gas vesicles in PBS was infused ∼10
s after the start of the experiment at a flow rate of 0.6 ml min −1 . After 65 s, a burst pulse …
