Weekend Educational Course
Physics for Physicists

Physics for Physicists: Part 3
Weekend Course

ORGANIZERS: Matthias Günther, Herbert Köstler

Saturday, 16 June 2018

N02

13:15 - 14:55

Moderators: Patricia Figueiredo, Maxim Zaitsev

Skill Level: Intermediate to Advanced

Session Number: WE-01C

Overview
This course will describe commonly used imaging pulse sequences and their building blocks, data acquisition and artifact suppression strategies, and basic image reconstruction techniques.

Target Audience
MR physicists and engineers, pulse sequence developers and clinicians who want to deepen their understanding of MRI acquisition and reconstruction methods. Individuals who will likely benefit most from the course are those who have recently completed or will complete a graduate educational program in MR physics, chemistry, applied mathematics or engineering and those practitioners of MR with extensive practical experience but seek to obtain a more systematic foundation.

Educational Objectives
As a result of attending this course, participants should be able to:
-Express a systematic understanding of pulse sequence building blocks and components;
-Show an in-depth understanding of advanced data acquisition strategies, and their potential and limitations;
-Describe common approaches to address motion;
-Describe state-of-the-art fast imaging techniques;
-Discuss advanced image reconstruction algorithms; and
-Identify common artifacts and understand how to reduce them.

	Echoes
13:15		Spin Echo, RARE, GRASE Jürgen Schneider Starting from the basic spin-echo sequence, this talk will subsequently introduce more advanced imaging sequence, which are based on multiple refocusing pulses. Advantages and technical challenges for these sequences will be discussed, and example applications will be given.
13:40		Gradient Echo Sequences Oliver Bieri The fundamental signal generation in magnetic resonance imaging (MRI) sequences is based on the principle of either spin echoes or gradient echoes or a combination of the two. This course elucidates concepts and basic properties of gradient echo methods with a special focus on fast gradient echo sequences.
14:05		Basic Preparation of Image Contrast Ute Goerke The lecture covers the basic principles of the molecular origin of image contrast, how the choice of sequence type and imaging parameters influence contrast and the implementation of additional sequence components to create a specific image contrast. The theory behind the presented concepts will be discussed and illustrated with examples from relevant applications.
14:30		RF Pulse Design Markus Barth This course part will cover the concepts to understand the theory and implementation of radiofrequency (RF) pulses including the small tip angle tip angle approximation, the Shinnar-LeRoux (SLR) algorithm and numerical methods.

	The Rest
15:15		Susceptibility, Flow, Chemical Shift, Motion Artifacts & Imaging Frederik Laun Following this lecture, the audience will understand the effect of magnetic susceptibility, flow, chemical shift, and motion on MRI. They will be able to use this knowledge to identify and minimize related artifacts or, alternatively, to measure the underlying effects.
15:40		EPI as Workhorse for Diffusion, Perfusion, fMRI.... Penny Gowland Traditionally MRI is used to produce high quality, high resolution images of the human anatomy. However it is also has the capacity to capture a range of dynamic processes in the body, and one of the best imaging sequences for doing this is EPI. This talk will consider the advantages and disadvantages of EPI as a readout scheme, its use in quantitative imaging and in imaging dynamic processes.
16:05		Arbitrary Trajectories: ACQ, Gradients, Reconstruction, Artifacts S. Johanna Vannesjo Cartesian k-space sampling on a regular grid provides optimal conditioning for image reconstruction. Yet, there are several reasons why it can be beneficial to deviate from the regular Cartesian sampling scheme. It may for example be to achieve faster coverage of k-space, to make use of self-navigating properties, to shape the point-spread function or to reduce the echo time. The most commonly used non-Cartesian acquisitions are radial and spiral sampling, but a large range of advanced sampling schemes have been explored. This presentation will cover basic considerations related to arbitrary sampling, from gradient waveform design to image reconstruction.
