1. A system for medical imaging, comprising:
a bed configured to support a phantom;
a scanner configured to detect coincidence events related to the phantom; and
a motion controller configured to move the phantom along an axis of the scanner to a plurality of phantom positions;
wherein the motion controller comprises a first motion controller, the first motion controller comprising:
a first moving mechanism configured to move the bed in a first direction or a second direction; and
a second moving mechanism configured to move the phantom in a third direction, the third direction is perpendicular to the first direction and the second direction.
