技術說明

　本專利發明技術旨在改良傳統寬頻磁振造影中所造成的影像模糊現象，使得在寬頻磁共振造影技術中所取得的快速影像能夠保有更多細節。 　　本專利所提出改良方法是透過磁振信號後處理的方法，達到快速取得且清晰的寬頻磁振造影。 　　本發明所屬技術領域並未曾有相關學術／商業發表，且本發明中的方法並非顯而易見或可輕易達成。需要寬頻磁共振技術相關專業知識以及數學理論輔佐方能達成，且本實驗室身為寬頻磁共振技術之開創者對於此一技術的研究與知識相對的完整，才能提出本項新發明專利。 A method and apparatus for enhancing signals in magnetic resonance imaging are provided. The method includes the following steps. Applying one or more than one RF pulse, which at least carries two frqeuncy components, and a slice/slab selection gradientto a subject, so that at least two slices/slabs of the subject respectively corresponding to the at least two frequency components are excited simultaneously. Applying a plurality of spatial encoding gradients and one or more than one separation gradients for separating the at least two slices/slabs. receiving a plurality of responsive RF signals excited from theject. The respnsive RF signals are restored according to a signal restoration function.
