Patent number: 7557574Abstract: The present invention relates to an imaging method and device for nuclear magnetic resonance. On the one hand, the method provides an image coding by means of an additional field which has, for each point of a two-dimensional grating surface within the sample, a different field strength value that occurs only once, as is the case, e.g., in fields based on fractal, surface-filling and space-filling curves. On the other hand, the read-out of the resonance behavior of a sample along a space-filling and/or surface-filling curve can be provided. In the first variant, a magnetic resonance (MR) image with a single high-frequency excitation without a time-varying gradient can be recorded, which in turn advantageously prevents the sound generation associated therewith. In the second variant, the sounds generated during read-out are advantageously shifted to another frequency range in which the human hearing is less sensitive.Type: GrantFiled: December 17, 2004Date of Patent: July 7, 2009Assignee: Forschungszentrum Julich GmbHInventors: Richard Patzak, Daniel Gembris, Stephan Appelt, Friedrich-Wolfgang Hasing, Horst Halling

Publication number: 20070229072Abstract: The present invention relates to a method as well as a device for analyzing a sample, in particular by MR spectroscopy in weak magnetic fields. The method according to the invention for analyzing a sample provides that a hyperpolarized medium is added to a sample and that the chemical shift is determined. The hyperpolarization causes a greater extent of alignment of the nuclei, thus improving the signal-to-noise-ratio in the measurement of the chemical shift. Thus, the sample is exposed to an alternating electromagnetic field and a static magnetic field B0, and the nuclear magnetic resonance is measured. Due to the hyperpolarization, comparatively weak static magnetic fields suffice for determining the chemical shift. Weak magnetic fields within the sense of the invention are fields having a strength of less than 200 G. For example, they are very weak fields in the range of under B0=0.001, T=10 G.Type: ApplicationFiled: June 1, 2005Publication date: October 4, 2007Applicant: FORSCHUNGSZENTRUM JULICH GMBHInventors: Stephan Appelt, Daniel Gembris, Horst Halling, Richard Patzak, Friedrich-Wolfgang Haesing, Ulrich Sieling

Patent number: 7202479Abstract: A method for assigning a pulse profile, in particular a pulse profile of a scintillation detector having at least two scintillation materials with different decay characteristics, to one of a plurality of pulse types with differing decay times, encompasses the method steps of: acquiring an output pulse profile and converting the pulse profile into an electrical signal whose amplitude-time profile represents the pulse profile of the output pulse; transforming the amplitude-time profile into the frequency space in order to obtain an amplitude-frequency profile representing the output pulse; normalizing the amplitude-frequency profile in order to obtain a normalized amplitude-frequency profile; comparing the normalized amplitude-frequency profile with a predetermined reference profile; and assigning the output pulse profile to one of the pulse types on the basis of the result of the comparison.Type: GrantFiled: December 23, 2002Date of Patent: April 10, 2007Assignee: Forschungszentrum Julich GmbHInventors: Hassan Saleh, Egon Zimmerman, Horst Halling
