1. A magnetic resonance apparatus comprising: a patient receiving sleeve; a thin main field magnet disposed around the patient receiving sleeve defining a thin imaging volume having a height, a width, and a thickness, which imaging volume thickness is (i) at least twice a slice thickness, (ii) less than 15 cm thick, and (iii) smaller than the imaging volume height and width; said magnet generating a main magnetic field which is uniform and temporally constant within said thin imaging volume which is transverse to a central axis of the patient receiving sleeve, which thin imaging volume is thin in a direction parallel to the axis of the patient receiving sleeve; a radio frequency coil disposed around the thin imaging volume; a patient support and transport means for supporting a patient and moving the patient axially, transverse to and through the thin imaging volume during a magnetic resonance examination.
