In recent years several review articles and books have been published on the use of
porphyrin-based compounds in photodynamic therapy (PDT). This critical review is focused …

Accurate quantification in PET and SPECT requires correction for a number of physical
factors, such as photon attenuation, Compton scattering and random coincidences (in PET) …

In this paper, the authors review the field of resolution modeling in positron emission
tomography (PET) image reconstruction, also referred to as point‐spread‐function modeling …

This paper describes a statistical image reconstruction method for X-ray computed
tomography (CT) that is based on a physical model that accounts for the polyenergetic X-ray …

Images of the inside of the human body can be obtained noninvasively using tomographic
acquisition and processing techniques. In particular, these techniques are commonly used …

In emission tomography statistically based iterative methods can improve image quality
relative to analytic image reconstruction through more accurate physical and statistical …

Image reconstruction from low-count positron emission tomography (PET) projection data is
challenging because the inverse problem is ill-posed. Prior information can be used to …

A megavoltage computed tomography (MVCT) system was developed on the University of
Wisconsin tomotherapy benchtop. This system can operate either axially or helically, and …

Recent advances in technology have enabled the combination of positron emission
tomography (PET) with magnetic resonance imaging (MRI). These PET-MRI scanners …

PET is a medical imaging modality with proven clinical value for disease diagnosis and
treatment monitoring. The integration of PET and CT on modern scanners provides a …
