Conclusions References Cat.Jour.Ling. 7 001-203:Cat.Jour.Ling. 10/10/08 17:12 Página 9 On the positive side, the work by Elliott raised attention to exclamative sentences, which, when considered at all, had received a parochial and secondary role with respect to interrogative sentences. It can be said with justice that Elliott set the grounds for a fruitful devel...

An analogy for the decoding of the MR signal through Fourier Transform - ANSWER-Basilar membrane processing sound Logically each line of phase encoding data is combined to allow the FT to determine the position along the y-axis. The number of phase encoding steps determines - ANSWER-the number of pixels along the y-axis In a gradient echo pulse sequence, which flip angle will produce a T2 weighted gradient echo image. - ANSWER->20 - <45 degree flip angle In a horizontal magnet, wh...
