Patent number: 9702950Abstract: A magnetic resonance imaging system (300) acquires magnetic resonance data (358) from a subject (318) that may include an electrically conductive object (e.g. an implant or a medical device). The magnetic resonance imaging system includes a radio-frequency transmitter (314) for generating a radio-frequency transmit field for acquiring the magnetic resonance data using a radio-frequency antenna (310). The radio-frequency transmitter has multiple transmit channels. The radio-frequency antenna comprises multiple antenna elements (312) each adapted to connect to an antenna element. The amplitude and phase values of the RF transmit field of each of the transmit channels can be selected such that the magnetic field generated by the RF antenna is minimized at the location of the electrically conductive object, thereby reducing RF heating of the object.Type: GrantFiled: August 15, 2012Date of Patent: July 11, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Hanno Heyke Homann, Ingmar Graesslin, Ulrich Katscher, Tobias Ratko Voigt, Olaf Helmut Dössel, Sebastian Alfred Seitz

Patent number: 9316710Abstract: A magnetic resonance sequence includes a repetitively applied radiofrequency pulse capable of causing a specific absorption rate (SAR) hot spot. The composition of the repetitive pulse is varied to generate versions of the repetitive pulse such that the SAR hot spot changes locations with subsequent applications of the repetitive pulse. To generate versions of the pulse, a pilot scan is performed to generate a patient model. A simulation of the SAR response to each of the versions of the repetitive pulse is performed to determine the location of SAR hot spot(s). A plurality of versions of the repetitive pulse is selected to be used in the magnetic resonance sequence.Type: GrantFiled: March 31, 2010Date of Patent: April 19, 2016Assignee: Koninklijke Philips N.V.Inventors: Ingmar Graesslin, Ferdinand Schweser, Peter Boernert, Paul Royston Harvey

Patent number: 8941380Abstract: In a method and apparatus to enable increased RF duty cycle in high field MR scans, a specific energy absorption rate (SAR) calculation processor calculates the local and global SAR or even a spatial SAR map. By incorporating additional information as, e.g. patient position, the SAR calculation accuracy can be increased as well as by using more patient specific pre-calculated information (e.g. based on different bio meshes), the so called Q-matrices. A sequence controller maybe provided to create a global SAR optimal RF pulse. After the optimal RF pulse is applied, the SAR and its spatial distribution are determined. SAR hotspots are also determined. Q-matrices within an appropriate radius around the hotspots are averaged and added to a global Q-matrix in a weighted fashion. After the global Q-matrix is updated, a new optimal RF pulse is created.Type: GrantFiled: April 13, 2009Date of Patent: January 27, 2015Assignee: Koninkijke Philips N.V.Inventors: Ingmar Graesslin, Sven Biederer, Ulrich Katscher, Ferdinand Schweser, Peter Boernert, Paul Royston Harvey, Wilhelmus Reinerius Maria Mens
