Patent number: 9817095Abstract: In one embodiment, an electromagnetic shielding of a device is disclosed for a magnetic resonance system. The device is shielded via a conductive layer which surrounds an inner part of the device in such a manner that an electrical current path completely around the inner part can be formed in the layer. The layer is arranged between a housing of the device, surrounding the inner part, and the inner part. In another embodiment, an electromagnetic shielding of a device is disclosed for a magnetic resonance system, wherein the device is shielded via a conductive layer which surrounds the device in such a manner that an electrical current path completely around the device is formed. In this situation, the device having the layer is mounted by way of projections on the magnetic resonance system. Each projection has a contact surface with the layer, at which the respective projection contacts the layer.Type: GrantFiled: June 27, 2013Date of Patent: November 14, 2017Assignees: Siemens Aktiengesellschaft, Siemens Medical Solutions USA, Inc.Inventors: James Corbeil, Ralf Ladebeck, Stefan Stocker

Patent number: 9606199Abstract: An automated blood sampling system for PET imaging applications that can be operated in or very near to the field of view (FOV) of an MR scanner, such as in a combined MR/PET imaging system. A radiation detector uses APDs (avalanche photo-diodes) to collect scintillation light from crystals in which the positron-electron annihilation photons are absorbed. The necessary gamma shielding is made from a suitable shielding material, preferably tungsten polymer composite. Because the APDs are quite small and are magnetically insensitive, they can be operated in the strong magnetic field of an MR apparatus without disturbance.Type: GrantFiled: October 29, 2008Date of Patent: March 28, 2017Assignee: Siemens Medical Solutions USA, Inc.Inventors: Johannes Breuer, Ronald Grazioso, James Corbeil, Nan Zhang, Matthias J.

Patent number: 8630693Abstract: In a magnetic resonance device having a PET unit for acquiring positron emission tomography data and a gradient coil, the PET unit includes a carrier tube on which at least one PET detector is arranged. In at least one embodiment, the carrier tube is arranged inside the gradient coil and is displaceably mounted in such a way that access to the PET detector is made possible by its displacement. This allows easy access to the PET detector during maintenance activities.Type: GrantFiled: March 2, 2009Date of Patent: January 14, 2014Assignee: Siemens AktiengesellschaftInventors: James Corbeil, Stefan Stocker

Patent number: 8018717Abstract: A facility is disclosed for cooling a detection device. In at least one embodiment, the facility includes at least one first cooling unit, through which a thermal contact to the detection device is able to be established and through which heat arising during operation of the detection device is able to be removed; and at least one second cooling unit, which is arranged so that heat from the environment of the detection device can be discharged through it. In at least one embodiment, this has the advantage of largely shielding the first cooling unit from incident heat which allows the detection device to be efficiently cooled.Type: GrantFiled: April 30, 2009Date of Patent: September 13, 2011Assignee: Siemens AktiengesellschaftInventors: James Corbeil, Stefan Stocker

Patent number: 7772559Abstract: A method for stabilizing the gain of a PET detection system with a cooling unit includes: determining the temperature of at least one component of the PET detection system, comparing the actual gain with a reference value, and actuating the cooling unit to influence the temperature such that the gain tends to the reference value. In at least one embodiment, the reference value is determined by determining the temperature of the at least one component during a test measurement, determining the gain during the test measurement, determining a functional dependence of the gain on the temperature, and selecting the reference value based on the gain to be stabilized. Advantageously, in at least one embodiment the gain can be kept constant using the described method in a simple manner, with the influence of the temperature of the components being taken into account.Type: GrantFiled: September 17, 2008Date of Patent: August 10, 2010

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
