| 20100025590 | COMPUTED TOMOGRAPHY GANTRY ROTOR - A rotor of a gantry of a computed tomography apparatus is produced at least in sections in a differential style from bar-shaped basic elements. Due to the differential style of the rotor, the rotation mass is reduced to a significant degree given a simultaneously maintained rigidity and stability of the rotor | 02-04-2010 |
| 20100025591 | COMPUTED TOMOGRAPHY ROTOR, AND GANTRY EMBODYING SAME - A rotor, and a gantry and a computed tomography apparatus with such a rotor, has recess to accommodate at least one component of an image data acquisition device, and the recess is dimensioned such that the component can be inserted therein in a radial direction proceeding away from a rotation center of the rotor and is positively connected with the rotor by an abutment structure provided on the component, as well as by spot connections. This positive fit thus acts in the direction of the centrifugal forces arising upon rotation of the rotor, such that an ejection of the component from the rotor is effectively prevented even given a failure of the spot connections (for example bolt connections) between the rotor | 02-04-2010 |
| 20100027757 | RIGID COMPUTED TOMOGRAPHY ROTOR AND METHOD FOR THE MANUFACTURE THEREOF - A rotor for a gantry of a computed tomography apparatus, as well as a manufacturing method for such a rotor. The rotor according to the invention is produced at least in segments from a composite material with polymer matrix that is reinforced with fibers. The rotor thus has a high strength and rigidity, such that the deformation limits to achieve a sufficiently good image quality with simultaneously low structural volume and low weight are not exceeded, even at high rotation speeds. | 02-04-2010 |
| 20100027758 | COMPUTED TOMOGRAPHY ROTOR RIGIDIFIED BY A METAL MATRIX MATERIAL - A computed tomography apparatus according to the invention ha a rotor that is produced at least in segments from a composite material with metal matrix reinforced with particles. Composite materials with a polymer matrix reinforced with particles have high specific strength properties and rigidity properties with simultaneously low material usage, such that high rotation speeds of the rotor can be achieved without negatively affecting the image quality in generated tomographical images. | 02-04-2010 |
| 20100027759 | COMPUTED TOMOGRAPHY ROTOR RIGIDIFIED BY A COMPOSITE MATERIAL WITH SHAPED BODIES THEREIN - In a rotor for a gantry of a computed tomography apparatus, as well as a manufacturing method for such a rotor, the rotor is manufactured as to contain shaped bodies (at least in segments of the rotor) produced from a composite material. By the integration of such shaped bodies with high strength and rigidity, the rotor can be stabilized in a targeted manner in the regions in which high stress values that arise upon rotation of the rotor. | 02-04-2010 |
| 20100080340 | AIR BEARING TO SUPPORT A BODY - An air bearing has a rotor having a circularly curved radial rotor bearing surface along its circumferential direction. The air bearing also has a stator having at least one radial stator bearing surface partially enclosing the rotor in the circumferential direction. The radial stator bearing surface is curved according to a profile following the circumferential direction of the rotor and is fashioned to generate an air gap between it and the radial rotor bearing surface so that, upon operation, the rotor is borne, supported by an air current in the air gap. The profile shapes the air gap such that, at a starting temperature that deviates from an operating temperature, the air gap has a smaller thickness (measured in the radial direction) in a second region of the radial stator bearing surface in comparison to a first region of the radial stator bearing surface along the circumferential direction. | 04-01-2010 |
