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.
