Abstract

In human-scale magnetic particle imaging (MPI), field inhomogeneities arise because a large fraction of the bore volume is utilized for imaging. Accurate knowledge of the receive-coil sensitivity is essential for hybrid system-matrix generation and model-based system matrix reconstruction. In this work, we present an efficient approach for measuring normalized receive-field profiles using a calibration coil and a small number of measurements.
