Abstract: An asymmetric electromagnet system, method, and method of producing an asymmetric electromagnet system, wherein the asymmetric electromagnet system is for generating an imaging magnetic field in an imaging region with an imaging isocentre, the imaging region being asymmetrically positioned within a gradient coil bore inside a magnetic resonance imaging (MRI) system during imaging, the electromagnet assembly comprising: an asymmetric gradient coil configured to generate a gradient field in the asymmetrically positioned imaging region, at least one gradient axis having the gradient field with a constant offset component such that the position at which the gradient field passes through zero is offset with respect to the imaging isocentre of the asymmetrically positioned imaging region.

Abstract: An automatic protocolling system and methods involving a processor operable by way of a set of executable instructions storable in relation to a nontransient memory device, the set of executable instructions configuring the processor to: receive information relating to an initial protocol comprising an initial ordering of a plurality of sequences, the information comprising data relating to an interaction extent value of at least one of an imaging system and a patient as a function of time corresponding to each sequence in the plurality of sequences, the data relating to a time-integrated effect of each sequence in the plurality of sequences; and dynamically determine an alternative protocol comprising an alternative ordering of the plurality of sequences based on the time-integrated effect, whereby an alternative protocol is provided.
