Enhanced and Robust Contrast in CEST MRI: Saturation Pulse Shape Design via Optimal Control
Clemens Stilianu, Christina Graf, Markus Huemer +5
Purpose: To employ optimal control for the numerical design of CEST saturation pulses to maximize contrast and stability against inhomogeneities. Theory and Methods: We appli…
A convex penalty for switching control of partial differential equations
Christian Clason, Armin Rund, Karl Kunisch +1
A convex penalty for promoting switching controls for partial differential equations is introduced; such controls consist of an arbitrary number of components of which at most one…
Efficient high-resolution RF pulse design applied to simultaneous multi-slice excitation
Christoph Aigner, Christian Clason, Armin Rund +1
RF pulse design via optimal control is typically based on gradient and quasi-Newton approaches and therefore suffers from slow convergence. We present a flexible and highly efficie…
Nonconvex penalization of switching control of partial differential equations
Christian Clason, Armin Rund, Karl Kunisch
This paper is concerned with optimal control problems for parabolic partial differential equations with pointwise in time switching constraints on the control. A standard approach…
