Patent ID: 8847597

Claim:
A magnetic field unit of a magnetic resonance tomography (MRT) system for acquiring an image of a head region forming a region to be scanned, comprising: a plurality of axially spaced permanent magnets having a closed shape, for production of a main magnetic field; a device, including a plurality of coils, for production of a gradient field; and at least one coil for generating and receiving radio frequencies, wherein the magnetic field unit is attached to a holding device in such a manner that a longitudinal axis of the magnetic field unit encloses with a vertical axis an angle of not more than ±45 degrees such that the longitudinal axis of the magnetic field unit and a vertical axis of a seated or standing patient enclose an angle of not more than 40 degrees, wherein the magnetic field unit and the patient can be moved relatively to each other such that the magnetic field unit can be positioned around the head of the patient, and wherein the plurality of coils in the device for the production of a gradient field and the at least one coil for generating and receiving radio frequencies are disposed in one or more gaps between the plurality of axially spaced permanent magnets.
