  • Publication number: 20180199852
    Abstract: Described is an MRI machine for measuring a head area of a patient, comprising at least one primary magnetic field unit, at least one gradient coil assembly, a closed patient opening, at least one excitation coil and at least one receiver coil. In a first region, a closed patient opening of the MRI machine comprises a first inner diameter perpendicular to a center axis of the MRI machine and, in the second region, a second inner diameter, which is arranged parallel to the first inner diameter. The first inner diameter is smaller than the second inner diameter, wherein the first region at least partially comprises the head area of the patient, wherein the second region at least partially comprises a torso area of the patient. The MRI machine is arranged obliquely, wherein, in a z-direction relative to a direction of the gravitational force, the center axis of the MRI machine comprises an angle between 20° and 75°.

  • Publication number: 20160313420
    Abstract: Disclosed is a scanning device for magnetic resonance imaging for medical diagnostics, more particularly for dental-medical diagnostics or ENT diagnostics, having a main magnet for generating a static main magnetic field having a homogeneous region, and having at least one transmitting and/or receiving coil for emitting and/or receiving a radio-frequency magnetic field. Provision is made, in particular, for the main magnet to be formed by two poles of magnetically opposite polarities at the end side, such that the static main magnetic field generated by the two poles at the end sides thereof, including the homogeneous region, projects beyond the end sides of the poles.
