Purpose To introduce new solution methods for the Bloch and Bloch-McConnell equations
and compare them quantitatively to different known approaches. Theory and Methods A new …

Magnetic resonance imaging (MRI) has evolved into an outstandingly versatile diagnostic
modality, as it has the ability to non-invasively produce detailed information on a tissue's …

Quantum optimal control (QOC) is a set of methods for designing time-varying
electromagnetic fields to perform operations in quantum technologies. This tutorial paper …

Phase contrast velocimetry relies on bipolar gradients to establish a direct and linear
relationship between the phase of the magnetic resonance signal, and the corresponding …

We analyze a recent claim that almost all closed, finite dimensional quantum systems have
trap-free (ie free from local optima) landscapes (Russell et al 2017 J. Phys. A: Math. Theor …

Optimal control theory is an effective tool to improve parameter estimation of quantum
systems. Different methods can be employed for the design of the control protocol. They can …

Conventional refocusing pulses are optimised for a single spin without considering any type
of coupling. However, despite the fact that most couplings will result in undesired distortions …

Purpose This article proposes a rigorous optimal control framework for the design of
preparation schemes that optimize MRI contrast based on relaxation time differences …

Non‐selective inversion pulses find widespread use in MRI applications, where
requirements on them are increasingly demanding. With the use of high and ultra‐high field …

We apply innovative mathematical tools coming from optimal control theory to improve
theoretical and experimental techniques in Magnetic Resonance Imaging (MRI). This …
