a function of gate width, lesion size, and motion amplitude. Smearing is quantified by the ratio …

… of lower SUVs, the respiratory phase during CT transmission scanning needs to be
measured or lung motion has to be regulated for imaging lung cancer in routine clinical practice. …

… a/Q) by imaging the lungs with positron emission tomography (PET) during a constant-… PET

… motion artifacts in PET images of lung cancer. The method is referred to as respiratory-correlated
dynamic PET (RCDPET). RCDPET enables the acquisition of 4-dimensional PET data …

… (2), a typical splitting artifact of a lung lesion on PET images is represented (section A).
When gating technique is applied (section B) the artifact is completely removed and the …

… synchronized gated PET images, and difficult to detect for all three motion models considered
in this work. This resulted in reduced efficiency in terms of motion compensation, as can be …

… PET data and that the clinical PET image quality can be improved using only a short additional
… present but there is a significant motion artifact at the lung–liver edge in the uncorrected …

… As respiratory motion is affecting quantification of PET images, … motion correction using
list-mode data without increasing acquisition time or reduced signal-to-noise ratio of the images. …

… The rebinned PET image by motion freeze approach was defined as PET MF . Quantitative
analysis was performed by comparing the SUV mean , SUV max⁡ , and tumor volume and …

… Our idea is to use respiratory gating for obtaining relatively motion free images of the lungs
… To correct the lung motion on the images, we need images with as less motion as possible. …
