Multi-Patch Sequences in Magnetic Particle Imaging
In this project we develop multi-patch imaging sequences and reconstruction algorithms for enlarged measuring fields in magnetic particle imaging (MPI). The regular field-of-view in MPI is limited due to physiological constraints such as tissue heating (SAR) and nerve stimulation (PNS). In practice typical FOV are in the range of 2x2x1 cm. In order to scan larger regions it is possible to shift the FOV to different positions and scan various smaller FOV, which can later be combined to a joint 3D dataset. Especially the reconstruction of multi-patch data is a computationally intensive and memory demanding task. In this project we develop algorithms for efficient reconstruction of multi-patch MPI data |
