A researcher in positron emission tomography and combined PET/computed tomography instrumentation. His 1998 study demonstrated attenuation correction using registered CT data, comparing methods for converting the CT image to a map appropriate for 511 keV PET photons. Tests with tissue-equivalent objects and human scans linked an imaging calculation to measured performance. The same CT acquisition can therefore supply anatomical localization and information needed to correct the PET signal for photon losses along its path.[ref]
