Filling Notes
Typically filling these phantoms is a multi-stage process, which is made simpler by the multiple sealing/filling points designed into this phantom. First, you would fill the two separate compartments from the bottom and make sure the third screw is tightened to seal the bottom of the uniformity region. Second, you would fill up the uniformity region through the largest rod from the top with the top piece completely removed. During this time you would also make sure each rod is filled with fluid. Third you would place the top piece on with the o-ring and seal it into place with the three top screws. Fourth, and lastly, you would top off the phantom through the center hole and seal it with the final screw and o-ring.
