The basic emission process associated with positron emission tomography (PET) imaging is
Poisson in nature. Reconstructed images inherit some aspects of this-regional variability is …

An advanced spatial-unfolding technique capable of reconstructing the activity distribution
within an exclusion zone from Compton gamma imager measurements taken outside of it is …

PET imaging is an important diagnostic tool for management of patients with cancer and
other diseases. Medical decisions based on quantitative PET information could potentially …

Objectives Many molecular imaging diagnoses involve comparing two regions of interest
(ROIs) in the image or different images. Since the images are obtained by measuring a …

When a scanner is installed and begins to be used operationally, its actual performance may
deviate somewhat from the predictions made at the design stage. Thus it is recommended …

In recent years, positron emission tomography (PET) has a wide range of clinical and
research applications in oncology, cardiology and neurology (Hoh, 2007). It is a unique …

Objective Positron emission tomography (PET) enables quantitative measurements of
various biological functions. Accuracy in data acquisition and processing schemes is a …

Kinetic mapping via mixture analysis [8],[10] involves comprehensive voxel-level analysis of
dynamic PET data. Bootstrapping from the fitted mixture model gives the ability to directly …

When a scanner is installed and begins to be used operationally, its actual performance may
deviate somewhat from the predictions made at the design stage. Thus it is recommended …

Positron emission tomography (PET) is a noninvasive medical imaging tool that produces
sequences of images describing the distribution of radiotracers in the object. PET images …
