Purpose 4-dimensional computed tomography (4D-CT)-based pulmonary ventilation
imaging is an emerging functional imaging modality. The purpose of this study was to …

Purpose Four-dimensional computed tomography (4DCT) ventilation imaging provides lung
function information for lung cancer patients undergoing radiation therapy. Before 4DCT …

The goal of this study was to present a method for physiologic validation and show results
for a comparison of the 4D-CT ventilation and SPECT ventilation or perfusion. A 4D-CT and …

Purpose A new form of functional imaging has been proposed in the form of 4-dimensional
computed tomography (4DCT) ventilation. Because 4DCTs are acquired as part of routine …

Purpose Computed tomography ventilation imaging (CTVI) is a highly accessible functional
lung imaging modality that can unlock the potential for functional avoidance in lung cancer …

RATIONALE AND OBJECTIVES: A novel ventilation imaging method based on four-
dimensional (4D) computed tomography (CT) has been applied to the field of radiation …

Purpose: Four‐dimensional (4D) computed tomography (CT) ventilation imaging is a novel
promising technique for lung functional imaging. The current standard 4D CT technique …

PURPOSE: Four-dimensional computed tomography (4DCT)-based ventilation is an
emerging imaging modality that can be used in the thoracic treatment planning process. The …

To determine the spatial overlap agreement between four-dimensional computed
tomography (4D CT) ventilation and single photon emission computed tomography (SPECT) …

A form of lung function imaging is emerging that uses phase-resolved four-dimensional CT
(4DCT or breath-hold CT) images along with image processing techniques to generate lung …
