Field Free Line Magnetic Particle Imaging [electronic resource] /
Erbe, Marlitt.author.
Marlitt Erbe provides a detailed introduction into the young research field of Magnetic Particle Imaging (MPI) and field free line (FFL) imaging in particular. She derives a mathematical description of magnetic field generation for FFL imaging in MPI. To substantiate the simulation studies on magnetic FFL generation with a proof-of-concept, the author introduces the FFL field demonstrator, which provides the world’s first experimentally generated rotated and translated magnetic FFL field complying with the requirements for FFL reconstruction. Furthermore, she proposes a scanner design of considerably enhanced magnetic field quality and efficiency. The author discusses the influence of magnetic field quality optimization on the image quality achieved using efficient Radon-based reconstruction methods, which arise for a line detection scheme, and based on this optimized design, presents a dynamic FFL scanner assembly. Contents Introduction of a Field Free Line for Magnetic Particle Imaging Magnetic Field Free Line Generation A Field Free Line Field Demonstrator Scanner Efficiency and Magnetic Field Quality Analysis Efficient Reconstruction Algorithms A Dynamic Field Free Line Imaging Device Target Groups Academics and practitioners in the fields of magnetic particle imaging, computed tomography, and medical imaging; radiologists and physicians. The Author Marlitt Erbe earned her doctoral degree at the Institute of Medical Engineering, University of Lübeck, under the supervision of Prof. Thorsten M. Buzug.
