… study is to develop and validate a simple and practical solution to the problem of respiratory
motion for the precise interpretation and quantitation of 18 FDG uptake of lung PET images. …

… PET/CT images of a lung phantom at rest and under simulated respiratory motion. The NEMA
2001 IEC body phantom, … 37, 28, 22, 17, 13, and 10 mm, was used in this study. To mimic …

… phantom for PET imaging that combines anatomic fidelity and a realistic breathing mechanism
with deformable lungs… to develop an anthropomorphic phantom for PET imaging, which …

… In addition to further phantom studies, the GRADIENT method needs to be validated in actual
patient PET images. An ultimate validation of any tumor-contouring method would require …
