Projection X-Space MPI Mouse Scanner

Here we describe the construction and images of the first projection x-space MPI scanner. The scanner is a side-access quadrupole design, and generates a 2.35 T/m main field gradient. The system excites the sample and receives signal in one axis, and reconstructs full-body images using x-space reconstruction. The resulting images are of high quality, and we demonstrate linear and shift invariance of the imaging system by imaging a resolution phantom and mice injected with Resovist.
