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…
Effect of Statistical Fluctuation in Monte Carlo Based Photon Beam Dose Calculation on Gamma Index Evaluation
Yan Jiang Graves, Xun Jia, Steve B. Jiang
The gamma-index test has been commonly adopted to quantify the degree of agreement between a reference dose distribution and an evaluation dose distribution. Monte Carlo (MC) simul…
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…
CT to Cone-beam CT Deformable Registration With Simultaneous Intensity Correction
Xin Zhen, Xuejun Gu, Hao Yan +3
Computed tomography (CT) to cone-beam computed tomography (CBCT) deformable image registration (DIR) is a crucial step in adaptive radiation therapy. Current intensity-based regist…
Optimal Surface Marker Locations for Tumor Motion Estimation in Lung Cancer Radiotherapy
Bin Dong, Yan Jiang Graves, Xun Jia +1
Using fiducial markers on patient's body surface to predict the tumor location is a widely used approach in lung cancer radiotherapy. The purpose of this work is to propose an algo…
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…
Four-dimensional Cone Beam CT Reconstruction and Enhancement using a Temporal Non-Local Means Method
Xun Jia, Zhen Tian, Yifei Lou +2
Four-dimensional Cone Beam Computed Tomography (4D-CBCT) has been developed to provide respiratory phase resolved volumetric imaging in image guided radiation therapy (IGRT). Inade…
