Marked locations in MR images on each metatarsal heads

The locations marked as the bottom of the metatarsal head are shown in the figure. Note that the slice levels at which each bottom of a metatarsal head was defined, are not the same. The slice level of the figure, on which the marked points are shown in red, is selected since the figure can show approximate locations of all the metatarsal heads in a figure. Hence, some points in the figure may not be located within the metatarsal heads.
