Details about Keynote and Tutorials
Lawrence L. Wald
Professor of Radiology, Harvard Medical School
Biophysicist, Massachusetts General Hospital
Director, MGH NMR Core, Martinos Center
Functional brain imaging has played an important role in recent advances in human neuroscience, allowing traditional psychology experiments to be carried out during non-invasive imaging sensitive to the metabolic or hemodynamic effects of brain activation. This has allowed human neuroscience to move from indirect measurements such as subject responses and reaction times to direct interrogation of the brain regions and circuits used in a task. The application of functional brain imaging has become so central to human neuroscience that most major psychology/neuroscience departments at US universities now operate an fMRI facility.
While fMRI is valued for its ability to noninvasively map the hemodynamic response to brain activation, its sensitivity is relatively low. Studies typically require repeated trials and are averaged across multiple subjects to achieve statistical significance. The consequence of low CNR extends beyond the inconvenience of averaging and missing subtle effects. It prevents fMRI from impacting clinical medicine where decisions must be made for an individual, not a group average. The ability to make statements about a brain circuit’s function or dysfunction in individuals could provide means of phenotyping spectrum diseases such as the major mental illnesses; a potential breakthrough for diagnosis and treatment.
MPI offers an attractive and potentially very sensitive compliment to fMRI. We propose using a similar hemodynamic contrast mechanism; the local Cerebral Blood Volume changes during activation. Since injected SPIONs do not cross the blood-brain barrier, the direct measure of SPION concentration provided by MPI is a measure of local CBV and CBV changes (~20% during brain activation) will be directly effected in a time-series of MPI images.
Lawrence L. Wald, Ph.D., is currently a Professor of Radiology at Harvard Medical School, Affiliated Faculty of the Harvard-MIT Division Health Sciences Technology and Sara & Charles Fabrikant Research Scholar at the Massachusetts General Hospital. He received a BA in Physics at Rice University, and a Ph.D. in Physics from the University of California at Berkeley in 1992 under the direction of Prof. E.L. Hahn with a thesis related to optical detection of NMR. He obtained further (postdoctoral) training in Physics at Berkeley and then in Radiology and MRI at the University of California at San Francisco (UCSF). He began his academic career as an Instructor at the Harvard Medical School and since 1998 has been at the Massachusetts General Hospital Dept. of Radiology A.A. Martinos Center for Biomedical Imaging.
His recent work focuses on improving methods for functional brain imaging. He has worked on the benefits and challenges of highly parallel MRI and its application to faster image encoding and parallel excitation and ultra-high field MRI (7 Tesla) methodology, and also improved method for studying the Human Connectome and portable MRI technology. Recent work has included studying the feasibility of functional brain imaging with Magnetic Particle Imaging (MPI) using Cerebral Blood Volume (CBV) contrast and analysis of the instrumentation needed for fMPI of humans. This has also led to extending understanding of Peripheral Nerve Stimulation (PNS) in human MPI and MRI using electromagnetic body models with full nerve atlases and a detailed neuro-dynamic model to predict magneto-stimulation thresholds. Dr. Wald is a Fellow of the International Society of Magnetic Resonance (ISMRM) and the College of Fellows of the American Institute for Medical and Biologial Engineering (AIMBE). He will serve as President of the ISMRM in 2019.
Tobias Knopp Section of Biomedical Imaging, UKE, Germany
MPI research groups worldwide have developed custom file formats for the storage of MPI raw data and calibration data. The Magnetic Particle Imaging Data Format (MDF) has been developed with the goal to standardize these efforts. It is very flexible and allows to describe data measured with spectroscopy systems and FFP / FFL based imaging systems. It is still very easy to use and interfaces for most programming languages are available. Within this tutorial we will give an introduction into the file format and discuss various design issues that were raised during the development of the MDF. The general structure will be discussed and typical usages are outlined. We present example scripts available for various popular programming languages performing a simple image reconstruction. The data and the scripts are openly available and can be accessed during or after the tutorial.
Tobias Knopp is a professor for Biomedical Imaging at the Section for Biomedical Imaging at the University Medical Center Hamburg-Eppendorf. He investigates MPI since 2007 with a special focus on image reconstruction and sequence development. Tobias Knopp is Editor-in-Chief of the International Journal on Magnetic Particle Imaging (IJMPI) since 2015.
Tobias Kluth
Center for Industrial Mathematics, University of Bremen
Finding sufficiently accurate models for the forward operator in MPI is still an open problem. The behavior of various components in the signal acquisition chain makes modeling MPI a challenging task. We consider the problem of mathematical modeling the signal generation in MPI. For proper modeling it is necessary to take the different components (applied field, analog filter, particle's magnetic moment dynamics, etc.) into account and to discuss potential model errors. Physical models for the dynamic behavior of the particle's magnetic moment (Brownian/Néel rotation) and their influence on the MPI signal are considered in this tutorial.
Tobias Kluth is a postdoc at the Center for Industrial Mathematics (ZeTeM), University of Bremen. He studied Industrial Mathematics focusing on nonlinear inverse problems and electrical impedance tomography. In 2015 he did his PhD in computer science related to neuroscience addressing aspects of neural information processing in the human visual system. Since 2016 he is a postdoc at ZeTeM working on inverse problems in the context of MPI. His major research interests include mathematical modeling of MPI with a strong focus on image reconstruction.
This tutorial will present some aspects of 3D rapid prototyping technologies that can enhance your MPI research and speed up your system development. We will focus on the usage of iterative prototype development, structural parts, imaging phantoms, and coil frames. As 3D prototyping has a lot of very geometry specific properties and a large amount of different parameter settings, beginning is a log way via try and error. With this introduction we will make you ready for starting with 3D prototyping within your own lab.
Thomas Friedrich studied physics at the University of Bayreuth. He did his PhD on magneto hydrodynamics in the department of physics in Bayreuth. As a postdoctoral researcher he joined the institute of medical engineering at the university of Lübeck, where he is working on magnetic particle imaging until today. Besides of using rapid prototyping for the development of MPI imaging hardware and phantoms, he also observes the technological development of “3D printing” with great enthusiasm. This enthusiasm combined with three years of experience in 3D printing will be shared with the participants of the tutorial.
Matthias Gräser studied electrical engineering and mechatronics at the Karlsruhe Institute of Technology. After his exam he joined the research team of the institute of medical engineering at the University of Lübeck and worked on Magnetic Particle Imaging and Spectroscopy where he finished his PHD in 2016. Within this time he developed new hardware concepts for field generators, receivers and the analog signal processing. One key feature that pushed the research in MPI is rapid prototyping. In this context Matthias Gräser gained experience with various 3D printing technologies including SLS, FDM and STL. Since 2017 he works as postdoctoral researcher at the University Medical Center Hamburg-Eppendorf.
The Lab-Visit will take place on Saturday, March 24 from 13:30.
At Saturday afternoon after the official program of the IWMPI the MPI research group at the UKE offers a lab visit for interested conference participants. The lab visit will give an overview about the local research activities and has a special focus on presenting tools that are necessary in a preclinical research environment. The demonstration includes a live-demonstration and describes the workflow for bimodal MRI-MPI imaging sessions. In addition customizations of the MPI scanner including a tailored mouse-body coil and an online reconstruction platform are demonstrated.
