NEMA NU 2–2007 measurements and GATE Monte Carlo simulations of GE Signa integrated PET/MR for pure and non-pure positron emitters

, 2019
NEMA characterization of PET systems is generally done with 18F. However, other PET radioisotopes, such as 68Ga and 82Rb are gaining clinical importance as they are of specific interest for oncological applications.

Performance evaluation of a whole-body prototype PET scanner with four-layer DOI detectors

, 2019
Parallax error caused by the detector crystal thickness degrades spatial resolution at the peripheral regions of the field-of-view (FOV) of a scanner. To resolve this issue, depth-of-interaction (DOI) measurement is a promising solution to improve the ...
