Patent number: 8706189Abstract: A combined PET/MRI device is disclosed. In at least one embodiment, the PET/MRI device includes an MRI unit for exciting nuclear spins in an examination volume and for receiving signals generated by the excitation in the examination volume, and a PET unit with a detector which surrounds the examination volume at least in part and is used for detecting radiation emanating from the examination volume, with, firstly, damping of the radiation emitted by the examination volume and, secondly, undesired interactions with electromagnetic fields of the MRI unit on the components of the PET/MRI device arranged between the examination volume and the detector being avoided due to the material properties and/or structural design of the components. Corresponding components such as, for example, patient couches, bearing or support apparatuses and local coils, are both MRI and PET compatible.Type: GrantFiled: July 8, 2009Date of Patent: April 22, 2014Assignees: Siemens Medical Solutions, Siems AktiengesellschaftInventors: Jürgen Hagen, Benedikt Hartinger, Volker Matschl, Rainer Paul

Patent number: 8191413Abstract: In a method for determining an NO2 concentration and/or a concentration ratio of NO2 and NO in an exhaust tract of a combustion device, such as an internal combustion engine, an NOx sensor that is sensitive with respect to NO2 and NO is utilized, which provides a NOx output signal correlating with an NOx concentration representing the sum of the concentrations of NO2 and NO. In order to determine the NO2 concentration and/or the concentration ratio of NO2 and NO, the NOx output signal of a first NOx sensor, which is arranged upstream of an exhaust gas treatment element arranged in the exhaust tract and having the capability of converting NO to NO2 and/or converting NO2 to NO, is compared to the NOx output signal of a second NOx sensor, which is disposed downstream of the exhaust gas treatment element.Type: GrantFiled: December 20, 2008Date of Patent: June 5, 2012Assignee: Daimler AGInventors: Jochen Lahr, Rainer Pauls

Patent number: 7965080Abstract: A phantom for use in quality control measurement of a fully integrated magnetic resonance/PET scanner is disclosed. The phantom features radiation activity distributed throughout an electrically conductive binder. Suitably, the binder is elastomeric and includes carbon fibers distributed throughout it to set the conductivity of the phantom to a desired level. The phantom is applicable to various multimodality integrated medical imaging systems such as MR/SPECT and MR/CT in addition to MR/PET.Type: GrantFiled: September 15, 2009Date of Patent: June 21, 2011Assignee: Siemens Medical Solutions USA, Inc.Inventors: Johannes Breuer, A. Andrew Carey, Xinli Liu, Volker Matschl, Rainer Paul

Patent number: 7768261Abstract: A phantom and method are provided for co-registering a magnetic resonance image and a nuclear medical image. The phantom includes a first housing defining a first chamber configured to receive a magnetic resonance material upon which magnetic resonance imaging can be performed in order to produce the magnetic resonance image. The phantom also includes three or more second housings configured to be attached to the first housing, where the second housings each define a second chamber configured to receive a radioactive material upon which nuclear imaging can be performed in order to produce the nuclear medical image and upon which the magnetic imaging can be performed in order to produce the magnetic resonance image. The first chamber has a volumetric capacity that is larger than a volumetric capacity of each second chamber.Type: GrantFiled: April 25, 2008Date of Patent: August 3, 2010Assignee: Siemens Medical Solutions USA, Inc.Inventors: Rainer Paul, Matthias J. Schmand, Charles H. Hayden, Jr., James Corbeil, Christian J. Michel, Ziad Burbar, Volker Matschl

Patent number: 7675028Abstract: A phantom for use in generating a normalization data set to be used in PET scanning (particularly integrated MR/PET scanning) is disclosed. The phantom features radiation activity distributed throughout a foam material. The foam—e.g., a polyurethane foam—may be produced by reacting two liquids, one of which is emulsified with water in which Ge68 has been dissolved. The foam produced thereby exhibits uniform distribution of radioactivity and a long mean free path for 511 keV gamma particles—two attributes that are important attributes of a PET phantom.Type: GrantFiled: June 23, 2008Date of Patent: March 9, 2010Assignee: Siemens Medical Solutions USA, Inc.Inventors: Johannes Breuer, Rainer Paul, Volker Matschl, A.
