Transverse Field MRI Apparatus

An imaging apparatus comprising a rotatable magnet assembly, that provides a rotatable B0 imaging field, and a controller configured to control the imaging apparatus to perform a method comprising:

• obtaining a first MRI image of an object in an imaging region based on a B0 imaging field;
• rotating the B0 field to change the orientation of the B0 imaging field with respect to the object;
• obtaining at least a second MRI image of the object;
• and
• determining an orientation of a structure within the object based on the orientations of the B0 imaging field with respect to the object, and the image intensity associated with the structure in the first MRI image, and the second MRI image.

A non-transitory computer-readable media comprising program instructions configured to program a programmable processor of magnetic resonance imaging apparatus comprising a rotatable magnet assembly, that provides a rotatable B0 imaging field, and wherein the programmable processor is configured to perform a method comprising:

• obtaining a first MRI image of an object in an imaging region based on a B0 imaging field wherein the magnetic resonance imaging apparatus comprises a rotatable B0 imaging field, and a controller configured to control the imaging apparatus and the method further comprising;
• rotating the B0 imaging field to change the orientation of the B0 imaging field with respect to the object;
• obtaining at least a second MRI image of the object;
• and
• determining an orientation of a structure within the object based on the orientations of the B0 imaging field with respect to the object, and the image intensity associated with the structure in the first MRI image, and the second MRI image.
