Positron emission tomography (PET) has shown an increase in both sensitivity and
specificity over computed tomography (CT) in lung cancer. However, motion artifacts in the …

This study proposes a new method to reduce respiratory motion artifacts in PET images of
lung cancer. The method is referred to as respiratory-correlated dynamic PET (RCDPET) …

We have developed a new technique to gate lung 18F-FDG PET images in synchronization
with the respiratory motion to reduce smearing due to breathing and improve quantitation of …

Motion is a source of degradation in positron emission tomography (PET)/computed
tomography (CT) images. As the PET images represent the sum of information over the …

Purpose To assess the performance of hardware-and software-gating technologies in terms
of qualitative and quantitative characteristics of respiratory motion in positron emission …

Combined PET/computed tomography (CT) is of value in cancer diagnosis, follow-up, and
treatment planning. For cancers located in the thorax or abdomen, the patient's breathing …

PURPOSE: To describe the degradation effects produced by respiratory organ and lesion
motion on PET/CT images and to define the role of respiratory gated (RG) 4D-PET/CT …

We previously reported that respiratory motion is a major source of error in quantitation of
lesion activity using combined PET/CT units. CT acquisition of the lesion occurs in seconds …

Our aim is to investigate the impact of respiratory motion on tumor quantification and
delineation in static PET/CT imaging using a population of patient respiratory traces. A total …

Positron emission tomography (PET) is a molecular imaging technique which provides
important functional information about the human body. However, thoracic PET images are …
