3D Image Reconstruction with accurate system modeling for the jPET-D4

The jPET-D4 is a novel brain PET scanner which aims to achieve not only high spatial resolution but also high scanner sensitivity by measuring 4-layer depth-of-interaction (DOI) information. In this work, we p...

An error in cerebral blood flow measured by ¹²³I-IMP single-photon emission tomography and a microsphere model

We studied errors arising from back flow from brain to blood and blood-borne radioactivity of ¹²³I-iodamphetamine (¹²³I-IMP), both of which are neglected in the microsphere model. We used an analytical approach t...
