584 Objectives: Mini-Explorer II is a high-resolution, high sensitivity PET/CT scanner which
is designed for human brain imaging and companion animal imaging. It is the prototype of …

240 Objectives: Analytic reconstruction algorithm such as Filtered backprojection (FBP) was
computationally efficient and considered to be quantitatively accurate for PET imaging …

1742 Objectives: The point spread function (PSF) in PET is spatially-variant and becomes
asymmetric away from the center of the tomograph. Modeling the PSF during iterative …

319 Objectives: One of the greatest challenges facing iterative fully-3D PET reconstruction is
the issue of long reconstruction times due to the large data size as compared to 2D mode. A …

3319 Introduction: This work presents a Monte Carlo simulation study to demonstrate that
the contrast recovery coefficients (CRC) and detectability of small lesions of a one-meter …

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 …

2056 Objectives Traditional PET reconstruction methods that do not take into account the
mispositioning of the lines of response (parallax error) result in blurring images and …

The SET-2400W is a newly designed whole-body PET scanner with a large axial field of
view (20 cm). Its physical performance was investigated and evaluated. The scanner …

Materials and methods Ninety patient scans acquired on the Philips CPET scanner at our
institution were reconstructed using 2.5-D RAMLA and 3-D RAMLA with differing …
