The quality of images reconstructed by statistical iterative methods depends on an accurate
model of the relationship between image space and projection space through the system …

The introduction of fast scintillators with good stopping power for 511-keV photons has
renewed interest in time-of-flight (TOF) PET. The ability to measure the difference between the …

Purpose In this article, we discuss dynamic whole-body (DWB) positron emission tomography
(PET) as an imaging tool with significant clinical potential, in relation to conventional …

PET has the potential to perform absolute in vivo radiotracer quantitation. This potential can
be compromised by voluntary body motion (BM), which degrades image resolution, alters …

The objective of this work was to evaluate the lesion detection performance of four fully-3D
positron emission tomography (PET) reconstruction schemes using experimentally acquired …

In recent years, different metal artifact reduction methods have been developed for CT.
These methods have only recently been introduced for PET/CT even though they could be …

TOF acquisition results in additional data dimensions that significantly increase data size.
Due to the redundancy of TOF information, data can be compressed almost without loss of …

In PET-CT the axial length of image reconstruction is defined by the CT scan, which delivers
an axial extend-dependent radiation dose. The beginning and end scanning points for CT …

A novel approach to reconstructing the principal directions of a diffusion tensor field directly
from magnetic resonance imaging (MRI) data using a tensor tomography data acquisition …

Calculating attenuation correction for brain PET imaging rather than using CT presents
opportunities for low radiation dose applications such as pediatric imaging and serial scans to …
