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 …

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 …

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 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 …

The growth of nuclear medicine at the end of the 20th century and the beginning of the 21st
has been caused mostly by recognition of the clinical value of coincidence imaging, or PET …

Objective: The purpose of this paper is to introduce technologists to the basic principles of
PET imaging and to the instrumentation used to acquire PET data. PET imaging is currently …

A whole-body PET scanner, without interplane septa, has been designed to achieve high
performance in clinical applications. The C-PET scanner, an advancement of the PENN PET …

Purpose We have developed a second‐generation virtual‐pinhole (VP) positron emission
tomography (PET) device that can position a flat‐panel PET detector around a patient's body …

Data acquisition is substantially different in PET than it is in planar nuclear medicine and
SPECT. There is an entirely different set of definitions and considerations. The objective of …

Depth-encoding detectors with single-ended readout provide a practical, cost-effective
approach for constructing high-resolution and high-sensitivity PET scanners. However, the …
