A researcher in quantitative medical imaging whose 2012 study tested computed tomography-based attenuation correction for positron emission tomography of bone. The study compared CT-derived linear attenuation coefficients with measurements made at the 511 keV energy of PET photons. Bone segments provided a controlled test object, while patient data tested the effect on reconstructed tracer uptake. The work shows why an anatomical image cannot simply be reused as an attenuation map without accounting for photon energy and tissue composition.[ref]
