Abstract: Disclosed herein is an MRI machine for measuring at least a portion of a head of a patient, having at least one primary magnetic field unit and at least one patient opening. The MRI machine has a patient seat, where the patient seat has adjusting means, which are driven by at least one drive means controlled by a control unit to move the patient seat into the patient opening along a travel curve as far as an imaging position, in which the head of the patient is arranged at least partially in an imaging area of the MRI machine, wherein an adjustable element is attached to the patient seat relative to the patient seat and wherein, by means of a detector apparatus, the position of the adjustable element relative to the primary magnetic field unit and/or relative to the patient seat is automatically determined on the MRI machine.

Abstract: The invention relates to a substrate material, which is highly porous and which is provided with a mechanically stable, component-penetrating framework structure made of alpha-Al2O3, to methods for producing the substrate material, and to the use of the substrate material.

Abstract: A bite device for the correct positioning of a patient when a panoramic X-ray is taken, comprising a holder part which can be placed in a fixed direction in relation to the X-ray device, a plate which can pivot against the holder and which is provided with a bite part into which a patient bites, and means for detecting the pivoting angle A between the plate and the holder part.

Abstract: The invention proposes a dental X-ray apparatus comprising a patient-positioning system arranged on a support and having a forehead rest. A horizontally pivotable bearing arm is arranged on the support, and the forehead rest is in turn arranged thereon.

Abstract: The invention relates to a dental x-ray device comprising a mobile support structure for a system that can be displaced to produce x-ray photographs and also comprising a fixed support structure. The mobile support structure is displaceably mounted on the fixed support structure by one or more bearings. The device is provided with adjustment elements for the displacement of the support structure parallel to the bearing surface, in addition to a drive for carrying out a rotation of the support structure about an axis that is perpendicular to the bearing surface. The bearing elements are configured in such a way that they can be displaced on the bearing surface in every direction parallel to the bearing surface and can carry out a rotation about an axis that is perpendicular to the bearing surface.

Abstract: In a dental patient chair that includes a patient bearing taxonomy in which specific treatment surfaces at teeth of the upper jaw and lower jaw are allocated to specific chair positions, an operating unit having an operating area on which the tooth rows of the upper and lower jaw are displayable as a diagram. The dental diagram is subdivided into a plurality of sections which represent treatment surfaces of those teeth for whose treatment identical or approximately identical chair positions are required. The sections are optically displayable on the operating area. Operating means are allocated to the sections, the adjustment means being activated upon actuation of said operating means for the purpose of adjusting the chair parts into the appertaining, selected chair position. The allocation of the operating means to the sections is defined by their arrangement, by colored or by structured fashioning.
