The whole-body lesion detection phantom consisted of a brain phantom, thorax with liver and lung compartments, and elliptical pelvis with bladder compartment. The lungs were filled with nylon mesh bags of Styrofoam beads, and the body and pelvis compartments were filled with a low water resistance open cell foam. 68Ge-infused silicone lesions were mounted in the mediastinum, lungs, abdomen, liver, and pelvis compartments. The close-up at the bottom shows an 8-mm lesion placed in the lung (black arrow), and a 12-mm lesion inserted into the open-cell foam of the body compartment (white arrow).
