20080204018 | METHOD AND MAGNETIC RESONANCE APPARATUS FOR SETTING A SHIM TO HOMOGENIZE A MAGNETIC FIELD IN THE APPARATUS - In a method for determination or adaptation of a shim for homogenization of a magnetic field of a magnetic resonance apparatus, which magnetic field is provided for the generation of magnetic resonance exposures of a specific examination region, an automatic determination, of a computer and/or supported by an operator on an image output unit of the computer, is made of a three-dimensional volume that is relevant for the determination or adaptation of the shim and that is matched to the examination region and/or an examination protocol by selection from an arbitrary morphology set of selectable volumes (which morphology set is not limited to specific shapes) and/or by generation of an arbitrarily three-dimensional volume not limited to specific shapes. The computer then automatically calculates the shim for the determined or selected three-dimensional volume. | 08-28-2008 |
20130317342 | PATIENT SUPPORT APPARATUS, AND MEDICAL IMAGING APPARATUS WITH A PATIENT SUPPORT APPARATUS - A patient support apparatus for supporting and/or transporting a patient is provided. The patient support apparatus may be used, for example in an imaging device. The patient support apparatus includes a patient support couch, on which the patient can be positioned for a medical imaging examination. A carrier unit is provided, on which the patient support couch is arranged so as to be moveable. The patient support apparatus also includes at least one drive unit for generating kinetic energy for a movement of the patient support couch in respect of the carrier unit. The at least one drive unit includes a pneumatic drive unit. | 11-28-2013 |
20140060381 | SELF-CONTAINED MOBILE RAILROAD MAGNETIC RESONANCE TOMOGRAPH - A railroad car for the accommodation and operation of a magnetic resonance tomography is provided. The railroad car includes a magnetic shielding of a volume for accommodation of the magnetic resonance tomograph. The magnetic shielding is designed to limit a magnetic scatter field outside a volume surrounded by the magnetic shielding to a value which is not hazardous to the environment, when a magnetic resonance tomograph is performing an examination in the interior of the volume. | 03-06-2014 |
20140062483 | MAGNETIC SHIELD FOR MR MAGNET - A magnetic shield for a field magnet of a magnetic resonance system is provided. A magnet apparatus with a field magnet for a magnetic resonance system with active shielding and a magnetic shield, wherein the magnetic shield forms a hollow body which accommodates the field magnets is also provided. A wall of the hollow body has a first, a second and a third area, which are disposed along the axis. In this case the second area separates the first area and the third area from one another and has a smaller wall thickness than the first and the third area. | 03-06-2014 |
20140084917 | MRI Scanner - A magnetic resonance imaging (MRI) scanner includes a control device, a gradient coil for generating a gradient field, a gradient coil connector for connecting the gradient coil to the control device, and a temperature sensor. The temperature sensor is configured and disposed to detect a temperature of the gradient coil connector. | 03-27-2014 |
20140354277 | Mobile Magnetic Resonance Tomography - A method for operating a mobile magnetic resonance tomography system having magnets and/or coils generating a magnetic field and a shield surrounding the magnets and/or coils is intended to enable an optimal image quality during the examination and at the same time have a small space requirement. For this purpose, a temperature is measured at a plurality of points on the shield by a temperature measuring system, where measured data of the temperature measuring system is sent to a compensation system, and where effects of temperature differences on the homogeneity of the magnetic field are compensated by the compensation system. | 12-04-2014 |
