The development of positron emission tomography/computed tomography (PET/CT)
scanners has allowed not only straightforward but also synergistic fusion of anatomical and …

This paper reviews recent advances in 4D medical imaging (4DMI) and 4D radiation therapy
(4DRT), which study, characterize, and minimize patient motion during the processes of …

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 …

Gating methods acquiring biosignals (such as electrocardiography [ECG] and respiration)
during PET enable one to reduce motion effects that potentially lead to image blurring and …

Respiratory motion in emission tomography leads to reduced image quality. Developed
correction methodology has been concentrating on the use of respiratory synchronized …

In positron emission tomography (PET), gating is commonly utilized to reduce respiratory
motion blurring and to facilitate motion correction methods. In application where low-dose …

Hybrid PET/MR combines the exceptional molecular sensitivity of PET with the high
resolution and versatility of MR imaging. Simultaneous data acquisition additionally …

The problem of motion is well known in positron emission tomography (PET) studies. The
PET images are formed over an elongated period of time. As the patients cannot hold breath …

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 …

Respiratory and cardiac motion leads to image degradation in positron emission
tomography (PET) studies of the human heart. In this paper we present a novel approach to …
