EPI in MRI
...shots used for purposes of acquiring the full image or even the length of the echo train per excitation (Ye et al, 1996, p.220). For instance, 32 shots having 256 phase encoding steps usually have an echo train length of 8.
For many years, the single-shot EPI has been the dominant class of pulse sequence in the majority of the imaging applications. Nevertheless, multi-shot acquisition, which we refer to as segmentation, has represented a viable alternative. Segmentation in EPI has brought about a number of advantages as will be discussed below (Ben, 2012). One of the key advantages...
