SPRITE acquisition

Total acquisition time has been further reduced with the development of half-ramp SPRITE. During a conventional SPRITE acquisition, phase encode gradients vary from -G to G and a full line of Ar-space is sampled during each magnetization cycle. As Ac-space data is assembled point by point. 

A centric scan SPRITE acquisition samples the central point of k-space first, such that no T1 weighting is introduced at the k-space origin. The local image intensity at any point in the image is thus given by...
