Quantitative PET imaging usually requires the arterial blood sampling, which is an invasive measure and may introduce risks or other complications to patients. People are trying several non-invasive methods to obtain the quantitative tracer concentrations by measuring the reconstructed intensity of the artery in the PET imaging. However, all these methods have certain limitations for brain study due...
Current clinical PET with 4-6 mm intrinsic resolution (6-9 mm practical) limits many important brain studies. The objective of this study is to use our existing technology for realizing an ultrahigh resolution high-sensitivity PET with a lower cost for neuroimaging. This proposed neuro-PET has a 54-cm detector ring diameter, a large 21-cm axial field of view (AFOV) for capturing the whole brain and...
