Magnetic resonance imaging (MRI) is a sophisticated and versatile medical imaging
modality. The inverse FFT has served the MR community very well as the conventional …

PET is a noninvasive molecular imaging modality that is increasingly popular in oncology,
neurology, cardiology, and other fields. 1–3 Accurate quantitation of PET radiotracer uptake …

We have constructed a three-dimensional (3D) whole body mouse atlas from coregistered x-
ray CT and cryosection data of a normal nude male mouse. High quality PET, x-ray CT and …

The problem of forming cross-sectional or tomographic images of the attenuation
characteristics of objects arises in a variety of contexts, including medical X-ray computed …

We evaluated the performance characteristics of the eXplore VISTA dual-ring small-animal
PET scanner, a stationary, ring-type, depth-of-interaction (DOI) correcting system designed …

Ordered subset expectation maximization (OSEM) is the most widely used algorithm for
clinical PET image reconstruction. OSEM is usually stopped early and post-filtered to control …

Objective Dynamic positron emission tomography (PET), which reveals information about
both the spatial distribution and temporal kinetics of a radiotracer, enables quantitative …

The addition of accurate system modeling in PET image reconstruction results in images
with distinct noise texture and characteristics. In particular, the incorporation of point spread …

MicroPET II is a second-generation animal PET scanner designed for high-resolution
imaging of small laboratory rodents. The system consists of 90 scintillation detector modules …

Emission computed tomography (ECT) is a technology for medical imaging whose
