摘要： Magnetic resonance apparatus is provided comprising a magnet having a first pair of coils arranged in a plane. The coils are operable in a counter- running manner when in use so as to generate a sensitive volume of magnetic field spaced apart from said plane. The magnetic field in the sensitive volume is arranged to have sufficient uniformity to enable magnetic resonance signals to be obtained from a target when located within the sensitive volume. The magnetic field direction Z is oriented to lie substantially parallel to the planes. The coils are arranged such that the sensitive volume is elongate in a direction X substantially parallel to the planes. A drive system is provided to cause relative movement between the magnet and the target so as to allow the sensitive volume to be moved with respect to the target.
