Abstract

The combination of CT and MRI for simultaneous image acquisition has not yet been successfully prototyped. To overcome the geometric conflict and electromagnetic interference between CT and MRI hardware, low-field magnet arrays are utilized. Using 3D magnetic field modeling software, several permanent magnet array designs are proposed yielding homogeneous field magnitudes of ~0.3-0.35 T. The results demonstrate potential configurations to enable interior MRI while working synergistically with x-ray hardware for simultaneous data acquisition.
