A full-ring PET insert device should be able to enhance the image resolution of existing
small-animal PET scanners. Methods: The device consists of 18 high-resolution PET …

We developed a prototype system to evaluate the feasibility of using a PET insert device to
achieve higher resolution from a general-purpose animal PET scanner. Methods: The …

PET imaging of rodents is increasingly used in preclinical research, but its utility is limited by
spatial resolution and signal-to-noise ratio of the images. A recently developed preclinical …

We evaluated the performance characteristics of the eXplore VISTA dual-ring small-animal
PET scanner, a stationary, ring-type, depth-of-interaction (DOI) correcting system designed …

We developed a prototype small-animal PET scanner based on depth-encoding detectors
using dual-ended readout of small scintillator elements to produce high and uniform spatial …

The article in this issue of The Journal of Nuclear Medicine by Chatziioannou et al.(1) about
microPET, a PET scanner for small-animal functional imaging, demonstrates the successful …

We proposed and tested a novel geometry for PET system design analogous to pinhole
SPECT called the virtual-pinhole PET (VP-PET) geometry to determine whether it could …
