发明名称 Pulse train, nuclear magnetic resonance tomograph and imaging method
摘要 The invention relates to a pulse train, to a nuclear magnetic resonance scanner, which comprises means for generating this pulse train, and to an imaging method in which the pulse train according to the invention is used. The pulse train according to the invention comprises an alpha high-frequency pulse, a preceding 180° pulse or a preceding 180° and a 90° pulse that precedes the 180° pulse, as well as a slice selection and a k-space line coding as well as an acquisition module, which is subsequent thereto for purposes of generating data. This invention is characterized in that the acquisition module for generating data results from at least two slices. By means of the pulse train and imaging method according to the invention, 20 slices of an image can be acquired at 16 different points in time for a matrix size measuring 256x256 during a measuring time of 8 minutes and 28 seconds. As a result, T1 relaxation times can be used for the first time for imaging methods in medical diagnosis.
