Initial Performance of a Prototype Small Animal PET Scanner Consisting of Long Semi-Monolithic Scintillator Detectors [PDF]

Sensors
Semi-monolithic scintillator detectors possess not only the inherent depth of interaction (DOI) encoding capability of monolithic scintillator detectors but also reduced edge effects compared to monolithic scintillator detectors.

Temperature dependence of the LabPET small-animal PET scanner [PDF]

2012 IEEE Nuclear Science Symposium and Medical Imaging Conference Record (NSS/MIC), 2012
INTRODUCTION In quantitative PET imaging it is important to correct for all image-degrading effects, for example detector efficiency variation. Detector efficiency variation depends on the stability of detector efficiency when operating conditions vary within normal limits.

Development of a PET Scanner for Simultaneously Imaging Small Animals with MRI and PET [PDF]

Sensors, 2014
Recently, positron emission tomography (PET) is playing an increasingly important role in the diagnosis and staging of cancer. Combined PET and X-ray computed tomography (PET-CT) scanners are now the modality of choice in cancer treatment planning.

Spatial Resolution and Sensitivity of the Inveon Small-Animal PET Scanner [PDF]

Journal of Nuclear Medicine, 2009
The Inveon small-animal PET scanner is characterized by a large, 127-mm axial length and a 161-mm crystal ring diameter. The associated high sensitivity is obtained by using all lines of response (LORs) up to the maximum ring difference (MRD) of 79, for which the most oblique LORs form acceptance angles of 38.3 degrees with transaxial planes.
