Recently, there has been an increased interest in imaging different pulmonary disorders
using PET techniques. Previous work has shown, for static PET/CT, that air content in the …

Purpose PET/CT acquisitions are affected by physiological motion, which lowers the
quantization accuracy. Respiratory-gated PET/CT methods require a long acquisition time …

1892 Objectives Respiratory motion is known to blur tumor in thorax and abdomen in whole-
body PET imaging, and thus reduce tumor's standard-uptake-value (SUV). To alleviate this …

In PET/CT thoracic imaging, respiratory motion reduces image quality. A solution consists in
performing respiratory gated PET acquisitions. The aim of this study was to generate …

672 Objectives: We present a method to compensate for respiratory motion during whole-
body PET imaging. While respiratory gated PET/CT is now clinically feasible, there are …

Pulmonary PET imaging is still immature relative to developments and experience in other
fields, such as brain, heart, and cancer. The reasons for this are several, including …

With the recent development of high resolution time-of-flight (TOF) positron emission
tomography (PET) and resolution recovery incorporated in the reconstruction algorithm …

537 Objectives: We assess the functionality of a respiratory gated PET/CT protocol that is
both clinically feasible and applicable to whole-body imaging. There are potential benefits of …

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 …

667 Objectives: We present an analysis of respiratory tracking signals for respiratory gated
whole-body PET/CT imaging. Clinical PET/CT systems use gating triggers derived from …
