PURPOSE: To determine whether setup margins can be reduced using cone-beam
computed tomography (CBCT) to localize tumor in conventionally fractionated radiotherapy …

PURPOSE: To implement a 3D dose verification procedure, based on in-room cone-beam
CT imaging and portal dosimetry, for lung cancer patients treated with stereotactic body …

We present treatment planning methods based on four-dimensional computed tomography
(4D-CT) to incorporate tumour motion using (1) a static field and (2) a dynamic field. Static …

Purpose: To compare tumor volume delineation using registered positron emission
tomography (PET)/CT vs. side-by-side image sets. Methods and Materials: A total of 19 …

PURPOSE: To investigate the usefulness of hardware coregistered PET/CT images for
target volume definition. METHODS AND MATERIALS: Thirty-nine patients presenting with …

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 …

Purpose: Many patients with non-small cell lung cancer (NSCLC) receive external beam
radiation therapy as part of their treatment. Three-dimensional conformal radiation therapy …

Purpose The purpose of this study was to clarify the dosimetric impact of 4-dimensional
computed tomography (4D-CT)-derived, ventilation-guided functional avoidance for …

Background: Understanding the three-dimensional (3D) volumetric relationship between
imaging and functional or histopathologic heterogeneity of tumours is a key concept in the …

Purpose: We present a validation study of CT and PET lung image registration and fusion
based on the chamfer-matching method. Methods and Materials: The contours of the lung …
