Patient motion impacts single photon emission computed tomography (SPECT), positron
emission tomography (PET) and x-ray computed tomography (CT) by giving rise to …

Small animal research is an essential tool in studying both pharmaceutical biodistribution
and disease progression over time. Furthermore, through the rapid development of in vivo …

Positron emission tomography (PET) is a non-invasive imaging technology employed to
describe metabolic, physiological, and biochemical processes in vivo. These include …

Minimally invasive monitoring of brain activity is essential not only to gain understanding on
the working principles of the brain, but also for the development of new diagnostic tools. In …

We propose a method to compensate for six degree-of-freedom rigid motion in helical CT of
the head. The method is demonstrated in simulations and in helical scans performed on a …

Noninvasive functional imaging of awake, unrestrained small animals using motion-
compensation removes the need for anesthetics and enables an animal's behavioral …

Background In preclinical positron emission tomography (PET) studies an anaesthetic is
used to ensure that the animal does not move during the scan. However, anaesthesia may …

PET scans of the mouse brain are usually performed with anesthesia to immobilize the
animal. However, it is desirable to avoid the confounding factor of anesthesia in mouse …

A comprehensive understanding of how the brain responds to a changing environment
requires techniques capable of recording functional outputs at the whole-brain level in …

Emission imaging incorporates both the development of dedicated devices for data
acquisition as well as algorithms for recovering images from that data. Emission tomography …
