Assessment of fiducial motion in CBCT projections of the abdominal tumor using template matching and sequential stereo triangulation
Oluwaseyi M. Oderinde, Hassan Mostafavi, Daniel Simpson +3
Purpose: To assess the fiducial motion in abdominal stereotactic body radiotherapy (SBRT) using the cone-beam computed tomography (CBCT) projections acquired for pre-treatment pati…
A method for real-time volumetric imaging in radiotherapy using single x-ray projection
Yuan Xu, Hao Yan, Luo Ouyang +5
In this paper, we present a new method to generate an instantaneous volumetric image using a single x-ray projection. To fully extract motion information hidden in projection image…
Comprehensive Evaluations of Cone-beam CT dose in Image-guided Radiation Therapy via GPU-based Monte Carlo simulations
Davide Montanari, Enrica Scolari, Chiara Silvestri +6
Cone beam CT (CBCT) has been widely used for patient setup in image guided radiation therapy (IGRT). Radiation dose from CBCT scans has become a clinical concern. The purposes of t…
Extracting respiratory signals from thoracic cone beam CT projections
Hao Yan, Xiaoyu Wang, Wotao Yin +6
Patient respiratory signal associated with the cone beam CT (CBCT) projections is important for lung cancer radiotherapy. In contrast to monitoring an external surrogate of respira…
A GPU Tool for Efficient, Accurate, and Realistic Simulation of Cone Beam CT Projections
Xun Jia, Hao Yan, Laura Cervino +2
Simulation of x-ray projection images plays an important role in cone beam CT (CBCT) related research projects. A projection image contains primary signal, scatter signal, and nois…
A comprehensive study on the relationship between image quality and imaging dose in low-dose cone beam CT
Hao Yan, Laura Cervino, Xun Jia +1
While compressed sensing (CS) based reconstructions have been developed for low-dose CBCT, a clear understanding on the relationship between the image quality and imaging dose at l…
Diaphragm as an anatomic surrogate for lung tumor motion
Laura I. Cervino, Alvin. K. Y. Chao, Ajay Sandhu +1
Lung tumor motion due to respiration poses a challenge in the application of modern three-dimensional conformal radiotherapy. Direct tracking of the lung tumor during radiation the…
