As I've defined my region of interest, The position may vary now (this is what i think) </span></div><div class="" style="background-color: transparent;"><span style="background-color: transparent;" class=""><br class="" style=""></span></div><div class="" style="background-color: transparent;"><span style="background-color: transparent;" class="">2. Also should I place the seed in all 63 slices to get segmentation in all slices(artery)? or multiple seeds in only one slice is enough?</span></div><div class="" style="background-color: transparent;"><span style="background-color: transparent;" class=""><br class="" style=""></span></div><div class="" style="background-color: transparent;"><span
