Patent number: 8788016Abstract: A device for radiation therapy implemented with image monitoring has a magnetic resonance device and an exposure device. The magnetic resonance device has a magnet and primarily serves for image monitoring an examination object of a patient in an examination volume of the magnetic resonance device. The exposure is fashioned to be static and serves to expose the examination subject in the examination volume with therapeutic beams. The patient (and therefore the examination subject) are supported by a patient positioning device such that the examination subject can be moved relative to the magnetic resonance device and the exposure device around at least one rotation axis.Type: GrantFiled: November 14, 2008Date of Patent: July 22, 2014Assignee: Siemens AktiengesellschaftInventors: Stefan Roell, Sebastian Schmidt, Anke Siebert

Patent number: 8260397Abstract: In a method to determine a kidney function parameter of kidneys of an examination person with the aid of magnetic resonance tomography, at least one magnetic resonance measurement is implemented for an examination region of the examination person that comprises a urinary bladder of the examination person, to acquire magnetic resonance data from the examination region that include at least image data. The concentration of a urophanic substance in the urinary bladder of the examination person is automatically determined based on the acquired magnetic resonance data. A volume of the urinary bladder is automatically determined based on the acquired image data. A kidney function parameter of the kidneys of the examination person is automatically determined on the basis of the determined concentration of the urophanic substance in the urinary bladder and of the specific volume of the urinary bladder.Type: GrantFiled: October 2, 2009Date of Patent: September 4, 2012Assignee: Siemens AktiengesellschaftInventors: Jan Ruff, Stefan Roell, Sebastian Schmidt

Patent number: 8238636Abstract: In a device, method and computer program product for generation of an exposure plan for irradiating a patient, at least one reference data set independent of the patient is provided, from which an attenuation of high-energy radiation upon passage through a reference body can be determined. A patient magnetic resonance image of the patient is adapted using the reference data set and an exposure plan is generated based on the patient magnetic resonance image and the patient-specific attenuation of high-energy radiation upon passage through the patient. The patient-specific attenuation of high-energy radiation upon passage through the patient is determined using the adaptation of the patient magnetic resonance image with the reference data set.Type: GrantFiled: May 23, 2011Date of Patent: August 7, 2012Assignee: Siemens AktiengesellschaftInventor: Stefan Roell

Patent number: 7610075Abstract: In a method for the operation of a medical diagnosis apparatus in an examination, a region of an examination subject to be imaged is placed in an imaging volume of the diagnosis apparatus, a first dataset of the region of interest is registered with a first set of operating parameters of the diagnosis apparatus, and the first set of operating parameters and the first dataset are stored. In a follow-up examination wherein the region of interest is again placed in the imaging volume, a follow-up dataset of the region of interest is registered with the apparatus operated with the stored, first set of operating parameters and the follow-up dataset is stored.Type: GrantFiled: December 6, 2002Date of Patent: October 27, 2009Assignee: Siemens AktiengesellschaftInventor: Stefan Roell
