Patent number: 9103897Abstract: A method of MR imaging and spectroscopy to reduce artifacts occurring due to the motion of an object to be represented, wherein the object position is determined quasi-continuously during the runtime of the MR acquisition, which includes one or more partial acquisitions (TA), and wherein motion correction is performed, which comprises dynamic adaptation of the frequency and phase settings of the RF system of the tomograph and of the orientation and amplitudes of the gradients during the runtime of the MR acquisition according to the current object position. The motion correction is thereby applied during a signal weighting period, during a signal read-out period, or between and/or during the two stated periods and the adaptations for motion correction are performed without interrupting or slowing the temporal progression of the MR acquisition. In this way, artifacts due to motion of the object to be represented can be further reduced.Type: GrantFiled: April 16, 2012Date of Patent: August 11, 2015Assignee: Universitaetsklinikum FreiburgInventors: Michael Herbst, Maxim Zaitsev, Julian Maclaren, Matthias Weigel

Patent number: 9097777Abstract: A method of MR imaging applies a magnetic field Bgrad1 having a spatially non-linear dependence to select a volume of at least one curved slice. The slice is described by its midsurface AM, a volume of the selected slice being made up of n? partial volumes in each of which gradients of at least one pair of remaining superimposed magnetic fields Bgradi (i>1) exhibit an angle dependence of 70° to 110° with respect to one another and with respect to the normal of the midsurface AM. At least one superimposed magnetic field of the respective pair exhibits a spatially non-linear dependence and combinations of these pairs are used for spatial encoding. In this way, curved surfaces can be mapped efficiently in high resolution and the method can be adapted to the slice shape.Type: GrantFiled: April 11, 2012Date of Patent: August 4, 2015Assignee: Universitaetsklinikum FreiburgInventors: Hans Weber, Maxim Zaitsev, Daniel Gallichan, Juergen Hennig

Patent number: 9009016Abstract: A method for measuring the cerebral perfusion of a living organism (1) by means of magnetic resonance (=“MR”) imaging proposes acquisition of further MR signals in a slice (5) that is pervaded by an artery that supplies the blood to the brain in order to determine the temporal progression of the concentration of the contrast medium during the bolus passage in the artery. During acquisition of the further MR signals, a magnetic field gradient is applied in such a way that projection images of the slice are generated. In each time interval between the excitations of the further MR signals, at least one radio-frequency (=“RF”) pulse is irradiated that causes saturation of the nuclear spin magnetization in the slice. This enables simultaneous measurement of the contrast medium flow in the vessels supplying the brain and the brain tissue within the same sequence with an adapted dynamic range.Type: GrantFiled: October 15, 2012Date of Patent: April 14, 2015Assignee: Universitaetsklinikum FreiburgInventors: Valerij Kiselev, Elias Kellner

Patent number: 8829004Abstract: The present invention refers to a method for inducing tumor apoptosis by influencing the ROS (reactive oxygen species) signaling pathway in tumor cells. Increasing the level of ROS leads to the selective inactivation of a tumor cell catalase and subsequently to an apoptosis of these cells. The level of ROS can be increased by increasing the level of nitric oxide through inhibition of the enzymes nitric oxide dioxygenase or arginase. According to the present invention inhibitors of the nitric oxide dioxygenase or arginase can be used for the manufacture of a medicament for the treatment of cancer. The present invention further provides a method for identifying compounds which can be used for the treatment of cancer, wherein the method allows to specifically identify compounds which induce apoptosis through the ROS signaling pathway. The present invention also provides a kit for identifying compounds which induce tumor apoptosis by inactivating a catalase on the tumor cell surface.Type: GrantFiled: September 27, 2012Date of Patent: September 9, 2014Assignee: Universitaetsklinikum FreiburgInventor: Georg Bauer

Patent number: 8823372Abstract: A method for magnetic resonance (=MR) imaging, wherein non-linear gradient fields are applied for the purpose of spatial encoding to acquire images of an object to be imaged and wherein the magnet resonance signal radiated from the object to be imaged is sampled on grids in time, to thereby obtain sampling points, is characterized in that the object to be imaged is mapped completely in regions of stronger gradient fields by increasing the density of the sampling points in the center of k-space, and additional sampling points are specifically acquired in the outer regions of k-space according to a k-space sampling pattern depending on the desired distribution of the resolution in the measurement, wherein the MR measurement is calculated with the additional sampling points. An MR imaging method is thereby provided by means of which homogenized resolution is achieved in the MR measurements using non-linear gradient fields for spatial encoding.Type: GrantFiled: March 16, 2011Date of Patent: September 2, 2014Assignee: Universitaetsklinikum FreiburgInventors: Hans Weber, Maxim Zaitsev, Daniel Gallichan, Gerrit Schultz
